Hello Mauricio, or anyone else affected, Accepted util-linux into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/util- linux/2.31.1-0.4ubuntu3.5 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: util-linux (Ubuntu Bionic) Status: In Progress => Fix Committed ** Changed in: util-linux (Ubuntu Xenial) Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1858802 Title: libblkid: no bcache UUID due to ambivalent detection of bcache and xfs_external_log for regular xfs in bcache backing device Status in util-linux package in Ubuntu: Fix Released Status in util-linux source package in Xenial: Fix Committed Status in util-linux source package in Bionic: Fix Committed Status in util-linux source package in Disco: Won't Fix Status in util-linux source package in Eoan: Fix Committed Status in util-linux source package in Focal: Fix Released Status in util-linux package in Debian: Unknown Bug description: [Impact] * Users with an XFS filesystem on top of bcache (this is seen on some ceph, cloud deployments) might fail to reference the bcache device by UUID or other udev properties. * The journal of the regular XFS filesystem in the bcache device is incorrectly detected as an XFS external log; so two superblocks are detected (bcache and xfs_external_log). * Thus blkid fails with ambivalent superblocks detected then doesn't provide the usual udev properties (UUID, etc.) * The fix improves the probe function for XFS external log so it detects it's regular XFS and bails out. [Test Case] * See test steps detailed in comment #7 and later. - Create an XFS filesystem with the journal/log in the beginning of the bcache device (< 256K). - Stop the bcache device. - Run '$ blkid -o udev -p $BCACHE_BACKING_DEVICE'. $ sudo make-bcache -B $BACKING_DEV $ sudo mkfs.xfs -d agsize=16m -l agnum=0 -f $BCACHE_DEV $ echo 1 | sudo tee /sys/block/$(basename $BCACHE_DEV)/bcache/stop $ sudo blkid -o udev -p $BACKING_DEV [Regression Potential] * The patch only changes the detection function for XFS external log to be more general about the sector where the magic of regular XFS may be found (which is shifted inside the bcache.) * It still checks at sector zero (the only one checked previously), so this behavior didn't change. * Possible regressions are actual XFS external log devices that are not anymore detected as such. (Although that would probably indicate a different bug in libblkid.)
