Thread: Won't detect disk partitions

  1. #1

    Default Won't detect disk partitions

    Long time SuSE / openSUSE user. I was looking forward to installing Leap 15 this morning, but quickly hit a problem.

    I have 4 hard drives in my system (all SATA, all pre-partitioned, all MBR partition table not GPT). However, the SuSE Partitioner only detected the partition tables for 1 of these 4 hard disks (sdc), and this disk was not the disk containing the partition I intend to install OpenSuSE Leap 15 on (sdd). The other 3 disks just listed a single device for the whole disk in the Partitioner.

    How do I get the Partitioner to read the partition table for a specific disk I specify (or for all disks, which IMO should have been the default)?

    I know this disk I want to install Leap 15 on is partitioned properly and working just fine as it contains the OpenSuSE 13.1 install that I'm posting from now!

    Did you check the downloaded iso?

    You haven't told us what you did. So I'm just guessing here.

    Did you try the expert partitioner?



    Use the "start with existing partitions" option. That should show all partitions that are found.

    Yes. And selected "Start with Existing Partitions". Here's more data as well: I unplugged every single hard drive in my system "except" the one I want to install SuSE 15.0 on (sdd), which is the same one that I am currently booting and running SuSE 13.1 on from a different partition. Expert Partitioner -> Start with Existing Partitions still wouldn't detect "any" partitions on that disk, despite the fact that it's a working disk that's already pre-partitioned. So, I flipped over to a shell (Ctrl-Alt-F2) and ran "fdisk /dev/sda". The partition output looked fine! All 8 partitions reported properly. ... however at the end of the partition report it said:

    Code:
    Partition 1 does not start on a physical sector boundary. < repeated for partitions 2..8 >

    After that, I tried "parted /dev/sda print", but it didn't work properly, reporting only a single partition of 1000GB (entire disk) of type fat16, giving all the appearances of seeing it as an unpartitioned disk (which it's not). That's strange considering that in SuSE 13.1, both fdisk and parted report the partition table properly. Here's the SuSE 13.1 output for parted and fdisk:

    Code:
    # parted /dev/sda print

    Do you mean did I generate the sha256 checksum and verify the integrity of the ISO I downloaded? Yes. EDIT: What is wrong with the editor on these forums? It just took out all the newlines in my entire post, so the code blocks are almost unreadable.

    I'm not having that problem. I'm using firefox. However, I have had similar problems with other browsers.

    I'm not sure what browser you are using.

    At the top left of the browser window, there's something that looks like A/A. If you click that, it will change the edit box to just show plain unformatted. You might have less problems with that. In particular, what you paste into the edit box will be text with no formats. Even with firefox, I sometimes find that useful.

    Now that I've got that fixed (Forum software quirk), let me repost that SuSE 13.1 parted and fdisk output for that disk I'm trying to install Leap 15 to:

    I'm not sure what browser you are using.
    Firefox 59.0.2. I post to another VBulletin Forum-based site every day and have never had this problem.

    However, playing with these forums, I found I had to disable the WYSIWYG editor in my General settings. Then the forum software here stops deleting all of my newline characters. But that's just weird. I post to another VBulletin-based forum every day and I've never had this problem there. EDIT: The problem may have been related to not giving opensuse.org and suse.org perms to run Javascript in my browser.

    I see what you're talking about now. Thanks for the tip. I'll keep that in mind for the future.

    And here is the Leap 15 parted and fdisk output for that same disk, which I just snagged from the DVD install using a shell and a USB flash drive:

    Partition 6 does not start on physical sector boundary.
    Partition 7 does not start on physical sector boundary.
    Partition 8 does not start on physical sector boundary.
    It seems like parted in Leap 15 has taken a step back from it's capability in SuSE 13.1. I wonder if that has something to do with the Leap 15 Partitioner's problem detecting the partitions on this disk.

    As YaST is based on libparted this likely explains why YaST does not see partitions. Please show full output of parted in Leap 15 for this disk.
