Thread: Is there a rollback mechanism in OpenSuse

  1. #1

    Default Is there a rollback mechanism in OpenSuse

    The reason I ask is I am faced with either a reinstall or a rollback. I don't remember seeing anything about rollback capability. I know that as of noon yesterday it ran fine but went south after a VM failed. Reinstalling is ugly as you get forced to lose all the libraries and files. So I have three questions


    1) Can I roll back the OS? And if not is it possible - I may have missed making restore points - I looked but could find how.

    2) If I reinstall and use the same username will it give me the same home dir?

    3) When the reinstall runs will it completely remake the file system. If I have to overwrite system directories that is bad but I would at least like to preserve my data and downloads

    You may try to solve the problem instead :-)

    Roll back is possible if you installed using btrfs filesystem. It is not
    that trivial, though.

    Yes.

    However, if you have several users, you have to be careful to create
    them in the same order, so that they get the same UID. Or do it manually.

    If you installed using a separate home partition, as recommended, you
    can keep all your personal files safe.

    If not, better make a backup.

    I have a separate home partition but whe20 attempt to upgrade I get a message I am almost out of disk space but it doesn't say where. So I deleted 20 GB on my home partition and told it not to install libreoffice and still I get the message when the install runs. If I don't select update will it blow away my home partition?

    I don't know if Linux is always this way but it seems as soon as it gets hard that's it. I get hung out to dry and calling them with credit card in hand was useless because they wont accept Canadian credit cards> Not much I can do at this point I am in it and have to proceed. I started this yesterday at about 3:00PM and other than sleep have been at it round the clock. Should I just reinstall and not upgrade. The upgrade is not too smart as it does not tell you where the space is needed so I am tempted to say overrite instllation but keep my home dir . I justr donrt know what options to select to do that.

    Why are you posting here ?

    Go and run windows !

    I've been using openSUSE for a couple of years - I never did regret it !

    Hi
    In YaST partitioner you can use the expert mode and tell it what to do,
    as in not format this or that. I use it all the time for my data
    partition as I leave /home alone 2...lol then using my /data partition
    I just create softlinks to the various common files and directories eg
    bin Pictures, .bashrc etc...

    You need to slow down and stop rushing, make notes on what you are
    doing, stop and think about what the system may do at the next step.

    If your the only user on the machine then if you don't format /home all
    will be fine (well until you upgrade the system to get to the latest
    apps etc).

    So go and investigate the partitioner and see what it may/may not do,
    this is probably then most important part of the install to understand.

    There is no paid support: your credit card, no matter what country it is
    from, is useless.

    There are only volunteers, and we work slowly, in our free time, and we
    also go to sleep now and then.

    So please calm down and take things slowly. Take a sleep, and come back
    tomorrow, explaining things carefully.

    You mention a VM.
    Are you running openSUSE in a Guest or is it the Host?

    If you are getting out of space errors, you need to address that first
    - Whether in Guest or Host, easiest way to display disk usage (used and free space) is to just use the File Manager of the Desktop you have installed.

    - Know there is a commonly experienced issue where the trash bin reports available space incorrectly. Search the Applications forum for trash bin posts related to the Desktop you're using to address. Usually it involves locating the metadata file that tracks the usage of the trash bin and deleting it... As a metadata file, it would be re-created but with the correct and accurate information.

    - If you're really running out of real disk space, then you may have planned your initial install incorrectly. Determine where you need additional space and use Partitioner to change if it's not the root ( / ) partition or something like gparted live to modify any partition on the disk (It's easy to use with a GUI but because its operations are low level the changes are risky. Backup or copy anything valuable)

    - Especially if this is a Guest VM, I often just trash it and launch a new instance, that's why once I have finished a base install of anything, I immediately archive a copy so I can create new Guest VMs without going through the whole install process again.

    In other threads he said that the problem started when xen failed. But at his level of understanding I'm not sure why he was playing with xen in the fist place.

    He has started about 5 or 6 threads on this.
