Looking at Gabriel's 2.16.1 patch, it looks like that is in the 2.17.2 code in Lucid and Maverick; so the question is - has this problem gone away in Lucid (or Maverick?) ?

[Bug 428318] Re: unable to mount an ext2 partition by label or uuid, unbootable system
Please consider fixing this in 9.10. I upgraded from 9.04 to 9.10 in preparation for the release of 10.04. I had no problem booting for several months. Then, all of a sudden, after updating and rebooting, I couldn't boot. Based on the error message, I created the symbolic link for my Ubuntu 9.10 partition in /dev/disk/by-uuid, rebooted and was able to use the system for another period of time. This time, I couldn't create the symbolic link and then boot (not sure why it worked the first time and after). I believe this partition was created (with gparted) as FAT32 and then changed to ext3 via gparted. The tools in the util-linux-ng package seem inconsistent. When I boot with a Ubuntu LiveCD (9.10 32-bit Desktop), I get the following: ubu...@ubuntu:~$ sudo fsck -t ext3 /dev/sda8 fsck from util-linux-ng 2.16 e2fsck 1.41.9 (22-Aug-2009) /dev/sda8: clean, 314232/3141600 files, 6959167/12611017 blocks (check after next mount) ubu...@ubuntu:~$ sudo blkid -p /dev/sda8 /dev/sda8: ambivalent result (probably more filesystems on the device) ubu...@ubuntu:~$ sudo sfdisk -l /dev/sda8 50173+ 56452 6280- 50444068+ 83 Linux If people think it's sufficient to let users just fix this themselves, then they are relegating Ubuntu Linux to the role of an O/S for developers and maybe server farm operators, but not as a desktop for home users or small businesses. To be usable by non-technical people, the partitioning tools need to convert partitions/create partitions that are acceptable to the other tools in the distribution. Replacement tools need to work with the limitations of the rest of the distribution (or there needs to be a reasonable non-technical way to fix the problem). -- unable to mount an ext2 partition by label or uuid, unbootable system https://bugs.launchpad.net/bugs/428318 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This should definitely be high priority. After upgrading from 9.4 to 9.10 I only managed to have my system working after several hours because I am knowledgeable about Linux. A normal user would have had their system unbootable without any hint of what is going wrong. Also, the fix is trivial and should definitely be backported, just use the newest util-linux package. -- unable to mount an ext2 partition by label or uuid, unbootable system https://bugs.launchpad.net/bugs/428318 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Worryingly, I've just encountered this whilst doing a dist-upgrade from 9.04 to 9.10. The 9.04 installation was a complete re-partition and install on an Acer Aspire one, so it's possible that the remains of the toy Linux distro it came with caused the confusion; also possible is that the problem is that the root filesystem is ext2. Whatever, an Acer Aspire one installed with 9.04 over the toy Linux and then upgraded to 9.10 is probably a pretty common trajectory.

I thought it might be sufficient to wipe the beginning of the disk in order to fix this. It wasn't sufficient. I finally wiped the whole disk.

[Bug 428318] Re: unable to mount an ext2 partition by label or uuid
Apologies for the delay in replying but I've been away for the last week. I fully take on board your comments and have reviewed the code in util- linux-ng-2.15, noting that libblkid now uses a completely rewritten method of probing for file systems. It's clear that this problem stems from the new detection routines in libs/blkid/src/probers/vfat.c. At the end of this file the struct blkid_idinfo is declared with some magic search strings. In particular, 2 patterns are defined to match the single byte jmp/bra opcodes at the start of a DOS boot sector. My /dev/sdb1 partition was once formatted for DOS and so matches these patterns and consequently the function probe_vfat is called. For these simple patterns the function probe_fat_nomagic is called to filter out false positives. In normal circumstances only MSDOS 2 and earlier floppies should be detected by this function. A very important feature of these disks is the boot signature - bytes 0x55, 0xaa at the end of the 1st sector which indicate to the BIOS that the disk is bootable. All MSDOS floppies have these bytes but the function probe_fat_nomagic doesn't test for them. When I used gparted to reformat this DOS partition to ext2 it overwrote the MSDOS system name (offset 3), the FAT16 magic signature (offset 0x36) and the boot signature at offset 0x1fe but left the BPB intact, which causes the confusion. To fix this I wrote a small patch which I have attached. I sincerely hope that you can add this to the 9.10 release in case it affects many other users with older systems. ** Attachment added: Fix false detection of FAT systems http://launchpadlibrarian.net/32621494/util-linux-ng-2.15.patch -- unable to mount an ext2 partition by label or uuid https://bugs.launchpad.net/bugs/428318 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 428318] Re: unable to mount an ext2 partition by label or uuid
Unfortunately it isn't a blkid bug, your filesystem type genuinely can't be determined because it contains multiple metadata. ie. it could be validly mounted as one of two filesystem types, one of which is going to be wrong and result in corruption. We generally recommend in this situation that you reformat the device involved with a tool that takes care to wipe other metadata first (e.g. parted). Since /boot is fairly small, you should be able to copy the data off to /tmp/boot, unmount, reformat, and copy back (adjusting fstab for the new UUID). If that's not possible, you can workaround the issue by changing the UUID in /etc/fstab to a hardcoded device name; however this will not work if your devices frequently change their assigned names (as can happen if you change SCSI or IDE layout, and on some machines even boot with USB devices plugged in). ** Changed in: util-linux (Ubuntu) Status: Incomplete = Won't Fix -- unable to mount an ext2 partition by label or uuid https://bugs.launchpad.net/bugs/428318 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 428318] Re: unable to mount an ext2 partition by label or uuid
I don't agree, this is a bug either in the base version of e2fsprogs used or in the Ubuntu patches. To prove this I built the latest e2fsprogs-1.41.9.tar.gz from SourceForge and ran sudo /home/lvr/e2fs/sbin/blkid -c /dev/null /dev/sdb1 /dev/sdb1: LABEL=boot UUID=41584c58-0cef-4d78-acd1-9a01ebd87833 TYPE=ext2 So the latest official tools have no difficulty in identifying the partition and type. Not only that but the line in /etc/fstab has the FS type fully specified so no excuses for not identifying it.

To prove this I built the latest e2fsprogs-1.41.9.tar.gz from SourceForge and ran While you don't agree, I'm afraid this is way things are. There are two detectable filesystem metadata on your block device. If we prioritised the one that's right for you, we would have bugs from everybody who wanted the other one. sudo /home/lvr/e2fs/sbin/blkid -c /dev/null /dev/sdb1 /dev/sdb1: LABEL=boot UUID=41584c58-0cef-4d78-acd1-9a01ebd87833 TYPE=ext2 So the latest official tools have no difficulty in identifying the partition and type. Not only that but the line in /etc/fstab has the FS type fully specified so no excuses for not identifying it. The official version of blkid comes from util-linux-ng, not from e2fsprogs.

No they don't, all the current releases might - but then the current release of Ubuntu does too. All of the development releases have standardised on the new blkid from util-linux-ng (which behaves as vol_id used to). So you'll find that ALL other major distros, in their next release, do not report the contents of your block device. This is a real killer bug for me. If Karmic ships with this bug then I will have to jump ships. Bon voyage. You'll find the same problem there too.
