Issues with Windows Clients, Samba, Virtual Box, VM Ware, RAID, Domain Controller, LDPA, iTunes

English Network/Internet
#1

Hi Penguins,

I have a number of installation and networking issues that are really confusing me and hope that you can help me untangle the web I’m in.

MY SYSTEM:

[ol]
[li]Motherboard : 760GM-E51 (MSI 7596) [/li][li]Processor: AMD Phenom II X6 2.7 GHz [/li][li]RAM: 16 GB, G.SKILL F3-10666CL7D-8GBRH [/li][li]Hard Drives[/li][LIST=1]
[li]Crucial M4 64 GB SSD [/li][li]2 x 2 TB Western Digital Red HDDs [/li][li]2 TB Seagate Barracuda Green HDD [/li][li]Plus USBs [/li][/ol]

[li]Video Card: ECS EliteGroup nVidia GT440 512 MB [/li][li]Network Cards :[/li][ol]
[li]Built-in Realtec [/li][li]PCI TrendNET [/li][li]PCI Intel [/li][/ol]

[/LIST]

MY GOAL:

Use SUSE 11.3/4 to network 2 Windows 7 PCs, 1 Windows 7 Notebook, 2 Windows XP notebooks, 1 TV and 1 PS3 while providing the following services and functionality:

[ol]
[li]Linux Primary Domain Controller [/li][li]LDPA for the TV and PS3 [/li][li]SSO and Roaming Profiles for the Windows Clients and possibly folder redirection for the Documents folder on Windows clients. [/li][li]Sharing approximately 2TB and growing of Pictures/Music/Movie sharing through Samba or may be through something else (any suggestions?); [/li][li]Sharing iTunes Library with the ability to update iPods/iPads/iPhones, possibly either via installing Windows 7 on a VM (not sure how this would work and appreciate any input) or via Samba [/li][li]Backup of systems to external 3 and 2 TB USB HDDs via AMENDA (this is probably the last step) [/li][/ol]

Wired gigabit connections will be established via CAT 6 cables, a Router and 2 Switches. Currently, everything works but there is no domain or workgroup.

ISSUES AND QUESTIONS:

SSD and HDD Setup:

[ol]
[li]I Plan to align the M4 Crucial SSD using sectors. Is this a good idea and is it recommended to use fdisk or parted? [/li][li]I would like to partition the M4 Crucial SSD as follows: /; /boot; /etc; /usr; /sbin; /bin. I would like to do this for ease of backup and to make sure that all read intensive filesystems exist on the SSD. I plan to put /tmp and /var and /swap (if needed) on a regular drive. Did I miss anything? Will there be enough space? Is there anything else that would need to go on a regular drive or vise-versa? Can anyone recommend sizes for these partitions given my goals? [/li][/ol]

RAID:

[ol]
[li]Thinking of going with software RAID 5 for the 2 x 2 TB Western Digital Red HDDs and 1 x 2 TB Seagate Barracuda Green HDD. Is this suited given the goals or would RAID 1 be better? Any suggestions? [/li][/ol]

GENERAL QUESTIONS:

I think that a lot of these issues are arising because I cannot find an iTunes replacement and just cannot figure out how it will work on Samba or Windows VM etc…

[ol]
[li]Which problem should I tackle first, setting up the domain controller or Samba? These are somewhat related given that the Domain Controller works via Samba, no? [/li][li]Is it worth it and is it possible to use a VM for Windows 7 to then install iTunes? Will it be possible for the VM to reach directly into a Samba share? Although this seems very awkward, I would like to do this so that iTunes could be updated and so that it would take care of all the metadata issues after media is imported. I would also like to do this in order to be able to connect all my apple devices. Any suggestions? Any other iTunes solutions short of having a separate server? [/li][li]Is it redundant to have Windows Folder Redirection given that everything will be backed up anyway? [/li][li]Since I am going for a Windows DC, should I use Samba or OpenLDAP or another solution? [/li][li]Since I will have a Windows DC, will that conflict with having a Windows in a VM to run iTunes? [/li][/ol]

Any help will be greatly appreciated.

This is to much for one thread I am afraid. Answers will trickle in by bits and pieces and discussions will simmer on about who knows what.

I will start this mess with:

There is no SUSE 11.3/4. As this is the openSUSE forums, at the moment the suppported version of it are openSUSE 11.4 and 12.1. openSUSE 12.2 is due to come out on 5 september.

About your partitions.
Not very many peolpe have a separate /boot. What is the reason you want one?
Not very many people spoil diskspace (and run the risk of one of them being full at some install) by putting things like .etc, etc. in different partitions. Normaly you do only backup files inside /etc because they contain changes configs (and that on file level, not on disk partition level). The rest of the system is best/soonest restored after a dissaster by reinstalling.
/tmp is nowadays a temporary fs in RAM, thus why put it on a disk?
/swap is not directory that is normaly in a system, but you could make such a thing, like you could make /blabla). I guess you mean a Swap partition.

In short, IMHO you have some ideas about how you want it, but you do not tell the arguments you have. Thus we can not realy understand why you want some of the things as you propose them here.
Just a few remarks to make you shiver. :frowning:

Hi there, and thank you for the response.

Yes, I meant openSUSE 11.4. Sorry for the confusion.

A while back in March I was experimenting with system backup (See: http://forums.opensuse.org/english/get-technical-help-here/install-boot-login/473113-backup-recovery-using-tar-dd-knoppix.html) using dd, tar, knoppix. The idea was to use only the standard utilities offered on the particular distribution as opposed to AMENDA or other available tools. Under that scenario I experienced a problem with GRUB not being properly restored by dd that was restoring the MBR.

It was suggested that having a small separate /boot partition that could be quickly imaged and restored may be beneficial (See http://forums.opensuse.org/english/get-technical-help-here/install-boot-login/473113-backup-recovery-using-tar-dd-knoppix-3.html (stating "> kbdeamon;2446053 Wrote:

If /boot is a separate, small partition, and grub is also installed there,
you could then dd the entire disk (because it is small) and restore it with
another dd. You should also backup and restore the mbr sector.

(from 11.4 x86_64 “Celadon” at Telcontar)"). In that case I was able to restore my system by rewriting grub, so avoiding this issue seems like a good reason to have /boot.

I do not understand:(. According to UNIX and Linux System Administration Handbook, Ch. 8 Pg. 232 (2010, 4th Ed.), it is a good idea to break out parts of the filesystem including /var, /usr, /tmp, /share and /home. Since the recommendation is to also have a backup root partition that has to be small, I thought that separating /etc is a good thing. I also thought that it could be beneficial in the scenario you describe above: running out of space. If I have it all in separate partitions I can add another disk, duplicate the partition and install no?

According to UNIX and Linux System Administration Handbook, Ch. 8 Pg. 232 (2010, 4th Ed.), putting /tmp on a separate filesystem puts a cap on temp file size and eliminates the need for backup. Although, I do intend of having /tmp in memory, I was not sure that 16 GB would be enough if I go the Windows 7/VirtualBox route and wanted insurance.

Correct I meant Swap area, the one that can be created during install. Sorry I did not know how to properly designated.

Yea I think the main problem is that I’m loosing sight of the big picture because I’m not sure how it all fits together particularly with respect to iTunes. I’m pretty comfortable installing the system and creating a basic Samba share on a 6 TB software RAID 5 (not sure if this is the correct way to say it). What I am not comfortable with yet is how do I have a Windows DC, Samba, VirtualBox Windows 7 and iTunes all running on the same system without issues.

May be I need to go back to the drawing board and split up the problem. Any suggestions. Thank you for the help.

GENERAL QUESTIONS:

I think that a lot of these issues are arising because I cannot find an iTunes replacement and just cannot figure out how it will work on Samba or Windows VM etc…

  1. Which problem should I tackle first, setting up the domain controller or Samba? These are somewhat related given that the Domain Controller works via Samba, no?

I suggest using Samba. Have a look at these blogs:

Samba S.W.A.T. - Samba Web Administration Tool Setup for openSUSE - Blogs - openSUSE Forums

AND

SWAT - Samba Web Administration Tool - Setup & Creation Script - 1.03 - Blogs - openSUSE Forums

  1. Is it worth it and is it possible to use a VM for Windows 7 to then install iTunes? Will it be possible for the VM to reach directly into a Samba share? Although this seems very awkward, I would like to do this so that iTunes could be updated and so that it would take care of all the metadata issues after media is imported. I would also like to do this in order to be able to connect all my apple devices. Any suggestions? Any other iTunes solutions short of having a separate server?

VirtualBox works well and worth a look for Windows programs:

http://forums.opensuse.org/content/59-how-install-virtualbox-opensuse-11-4-12-1-tumbleweed.html

  1. Is it redundant to have Windows Folder Redirection given that everything will be backed up anyway?

Not sure I understand the question. Its OK to use Windows NTFS partitions in openSUSE and to use Samba to access remote copies of Windows. I use Windows to backup Windows and Linux to backup Linux.

  1. Since I am going for a Windows DC, should I use Samba or OpenLDAP or another solution?

Setting a Windows Domain may be required for a business, but not required for home or even a small Office usage as Samba provide good file sharing.

  1. Since I will have a Windows DC, will that conflict with having a Windows in a VM to run iTunes?

Not as far as I am concerned. It should not create a problem.

Any help will be greatly appreciated.

Thank You,

I do not know if pointing to a book which few of us have read will help in clarification why to do the partitioning like you suggest. We are not going to read that book because you used it. You have read it and hopefully understood it such that it’s recommandations are not something to follow blindly, but according to your situation. That means IMHO that you yourself should at least have an idea why you would make a separate /usr and /bin and /sbin (where /sbin is a particular bad idea IMHO), not because some book (or, most often today, because somewhere on the Internet) it says so, but because you , reading Pros and Cons here and there, decided that in your case it is the best thing to do. Of course you can ask here, but then we want to know why you propose to do it this way. Thus we can add Pros/Cons, or explain why your’s are less important then you thought.

Same for your question about RAID. We can not decide if one solution would be better then the other. Better for what? Are you going for 9999? Are costs important? It seems that you are designing something that is more then a home system, but the real message is not understood by me.

The above because I do know something about sytem design in conjunction with partitioning. I have no comment about anything in connection with Windows because I have no knowledge there.

Hi jdmcdaniel3,

thank you for the reply. I will give all these a look.

I was thinking of redirecting the My Documents to Linux (i.e., actually saving all the documents to a Samba share) but I’m not sure whether it will be useful.

Thanks again!!!

Hi Henk, and thank for your reply. I really appreciate you engaging in this dialogue for it is helping me figure out how exactly I should partition my system and it is making me think about things that I have not previously considered.

Now, I do not have much Linux experience so I have to resort to certain educational materials to set things up. That does not mean that I follow the advice blindly as I’m asking questions here. The title I listed is a reputable one but I do not keep a tally on how many people have read it. Neither do I expect that many or all have read it. What I do expect is that the reasoning offered by the title is clear: maintaining separate partitions for /, /usr, /var, /tmp and /home leads to an organized, scalable system that is easier to maintain. That is what I took away from the book and that is the principle that I am adhering to in proposing the partition scheme above.

In particular,

/ should be separate to ease backup and to have a fallback in the event that the primary/normal / gets corrupt. Thus it makes sense to me to have a separate small root to boot from on a separate disk.

/boot may be separate to ease backup and restore. I’m on the fence with this one, but given my previous backup/restore experience above, it seems that it will be easier with respect to GRUB.

/usr may be broken out into a separate partition so it would be easier to duplicate /. Plus, it makes sense to breakout /usr, at least for me, where /usr contains most standard programs and is likely to grow.

/var should be separate and on a regular HDD as opposed to an SSD because it holds many logs that will be written to. Placing it on a separate spindle HDD will save on writes to the SSD, will contribute to the goal of having a small /, and will limit the space used by logs and other accounting information thus preventing /var from filling / and bringing the system to a halt.

/tmp may be broken out to a regular HDD but I’m not sure that it has to be given that it will be in RAM. I do not have any particular reason for breaking out /tmp since I do not fully understand the consequences of placing /tmp in RAM. In other words, will /tmp exist in / on the SSD if it is RAM?

/home should be separate to keep / small and to separate user data from the system. I think we all agree on this.

I though of breaking out /etc /bin and /sbin due to their significance within the system. Its a poor reason and the more I consider it the more I lean towards leaving them alone.

Thus, it seems that I’m left with
/ (on SSD)
/etc
/bin
/sbin
…
/boot (on SSD)
/usr (on SSD)
/var (on separate HDD not SSD)
/tmp (on separate HDD not SSD and in RAM)?
/home (separate HDD not SSD)
Swap (just in case)?

I am not sure to what other costs you are referring other than hardware costs. That said all I am concerned with is having a Windows DC for my windows clients, a backup solution for my Windows and Linux, and a way keeping iTunes on Linux while sharing the iTunes libarary with all clients and making sure that any apple devices connected to any of the clients can be updated and maintained. That is the big picture I suppose.

Thoughts on partitioning? Any other thoughts? I really appreciate the help. Thank you very much!!!

#8

Let me say first that using an SSD does really speed up your boot times and helps with anything that reads the disk a lot. That being said, we know that SSD’s are much lower capacity AND, the more partitions you use, the more what little free space you have is split and perhaps ends up in the wrong place, thus causing your copy of Linux to stop running after one of the partitions gets full. So, with that in mind, I would put ALL of root /, except for /home and swap, on a single SSD with a single partition. That way, all of the folders you mention, share the same free space pool. On the two SSD’s I use, system one, running openSUSE 12.1 is using 17.3 GB while system 2 running openSUSE 12.2 RC2 is using 16.7 GB. System 1 was reloaded under a year ago when my first SSD went bad. System 2 was reloaded just after 12.2 RC2 came out. IN both cases I use a seperate /home partition and the same disk contains the SWAP partition. In both cases I could have put SWAP on the SSD with little trouble, but I have lots of memory and only hibernate seems to use it. I suggest you make it easy on yourself and stick with a single / root partition on your SSD. IF you get a large one, like a 256 GB, you would have no problem keeping /home there as well, but this depends on what you put in /home. I use a 500 GB /home + SWAP drive myself on both systems.

Thank You,

#9

Thank you so much!!! This makes a bit more sense now:) Question, the SSD is a 64 GB Crucial M4 and the system does not have any more room for more drives. However, I like your setup. In your opinion, do you think I’ll be OK if I split the SSD into 2 partitions of 32 GB; one to hold openSUSE 11.4 and the other to try openSUSE 12.2? I’m thinking that I would transfer to 12.2 once I feel comfortable and I guess what I’m looking for is to get some sort of idea of the types of things that are fitting into 17.3 GB.

#10

So, if this was me, I would forgo installing openSUSE 11.4 and go for 12.2 is just a few days. OR, install 12.2 RC2 now, then do this:

su -
password:
zypper up
zypper dup

This will put you at the GM point I think. The basic problem between 11.4 (or 12.1) and using 12.2 is the grub boot loader. 12.2 uses Grub 2 while 11.4 uses Grub Legacy and there are many other reasons I feel. Further, instead of splitting your time setting up two, go for just one and get it just the way you want. Finally, if you have another drive with enough room, consider using VirtuallBox to run 11.4 if there is a real good reason to do so. For 64 GB, I really feel I would give it all to openSUSE 12.2 and find other ways to play around with different Linux Distros like using VirtualBox.

Thank You,

#11

Thank you. I will definitely get 12.2. The only issue I have with it is Gnome. I just installed 11.4 though and almost went with your advice (this was before your post). I split the SSD up into 2 partitions but I feel that I will redo everything the way that you are suggesting once I get 12.2.

There is an oddity with this installation though. I did everything that you have suggested except for the SSD part. I put /home and swap space on a separate External HDD enclosed and hooked up via SATA. Everything is working except for the Swap: the system refuses to Hibernate and sometimes it seems to attempt to mount the the swap sapce.

fstab reads as follows

@linux-5b3g:~> cat /etc/fstab
/dev/VolGrp00/LogVol01 swap                 swap       defaults              0 0
/dev/disk/by-id/ata-M4-CT064M4SSD2_000000001201032F429D-part1 /                    ext4       acl,user_xattr        1 1

/dev/VolGrp00/LogVol00 /home                ext3       acl,user_xattr        1 2
proc                 /proc                proc       defaults              0 0
sysfs                /sys                 sysfs      noauto                0 0
debugfs              /sys/kernel/debug    debugfs    noauto                0 0
usbfs                /proc/bus/usb        usbfs      noauto                0 0
devpts               /dev/pts             devpts     mode=0620,gid=5       0 0

My /home and Swap exist as logical volumes on the external drive. The Swap is 32 GB. When I log into Gnome, I a disk/device Icon that reads 32 GB Filesystem. Exploring it only leads to a lost+found directory. The 32 GB Filesystem is presumably the Swap space. I have never seen this before and it does not seem to always get mounted after a reboot.

Thoughts? Is this supposed to happen? If not, how can I fix it? Is it because it is an external drive? I configured it this way because I have 3 2 TB drives in the box setup for RAID 5 and did not want to use it for swap.

so it seems that swap is working. But why am I getting that icon? May be i’m doing something wrong with Hibernate?

#13

So the device name looks kind of odd for SWAP “/dev/mapper/VolGrp00-LogVol01” and is not in the normal format of disk/by-id or even UID. When you saw there is an icon, where is this icon showing up? It is certainly true that SWAPO should be mounted like a normal partition. I recently posted a blog on SWAP you can read about here:

Setting up the Proper Size SWAP File in openSUSE - Blogs - openSUSE Forums

Thank You,

#14

I’ll give the blog a look.

I generally see the device on the desktop. Just restarted the system and the device is not there. However it is listed in Natilus.

I still get the same thing when I run the commands above.

linux-5b3g:~ # swapon -s

I I click on the device in Natilus I get an authentication request after which the devices appears on my Desktop as mounted.

The output from the above commands remains the same and I would venture to say that Swap is activated.

linux-5b3g:~ # swapon -s
Filename                Type        Size    Used    Priority

I think I figured it out. I believe that this device refers to the partitioned but unused space on the SSD but I can’t confirm this because I just corrupted my file system. This gives me a chance to go back and follow your recommendations.

Please keep us abreast of your progress and we wish very good luck.

Thank You,

Impossible. You can not put /etc on a separate partition.

Even having /usr as a separate partition is becoming inconvenient, many devs do not want to support
that, and it does have issues (emergency mode, for instance). So much for your book :stuck_out_tongue:

Not yet. The point is argued but there is no consensus on it, yet. Some temporary spaces are put in
RAM, but not /tmp as a default for every system.

No, having / separate from the rest will not help in emergencies, you can not boot it without the
rest. Emergency mode without /usr becomes useless nowdays.

If you want to have a rescue system for emergencies, install another openSUSE complete in another
partition. A small Linux, but complete. 8 GiB suffice.

Only if grub is installed in that partition and the MBR is generic.

(Notice that many people here prefer to do a reinstall instead of a bare bones restore)

You are not giving any valid reason for /usr in a separate partition, and I’m one of the people that
defends using a separate /usr, so I know advantages and disadvantages (and I’m not talking).
You told none :stuck_out_tongue:

In other words, do not do it unless you really know why and what you are getting into.

Well… I will not comment on the SSD issues. As for needing this separation on a home system… I
doubt it.

It will not be in RAM in 11.4 unless you do it manually. Nor in 12.1, nor in 12.2 AFAIK.

Of course not.

It is impossible to separate them. If you think it can be done, read that book of yours again. If
then you still think you can, throw that book to the garbage!

Thanks, I’ll give this some thought.
