http://bugzilla.suse.com/show_bug.cgi?id=1139948 Bug ID: 1139948 Summary: LVM LV cannot be used as Bcache cache device (and possibly backing device) Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 Assignee: yast2-maintainers@suse.de Reporter: ancor@suse.com QA Contact: jsrain@suse.com CC: ancor@suse.com, luizluca@tre-sc.jus.br, snwint@suse.com Depends on: 1139783 Found By: --- Blocker: --- +++ This bug was initially created as a clone of Bug #1139783 +++ I decided to keep the original one to track the AutoYaST issue (which ignores an LV been used as part of a bcache setup) and create this clone to track the problems with bcache triggered by using the Expert Partitioner. Using such tool, the user can use LVM LV for bcache. It accepts nicely until it actually do partitioning. It tries to run: # /usr/sbin/bcache set-cachemode /dev/system-slow/home-back writethrough Error:Wrong device name found While this one works: # /usr/sbin/bcache set-cachemode $(readlink -f /dev/system-slow/home-back) writethrough It accepts /dev/dm-* but not /dev/system-slow/home-back. The same goes with "bcache attach" that does not follow symlinks. After installation finish, it works as expected. The only caveat (probably related) is that systemd waits until it times out for a resume= device (kernel cmdline resume=/dev/disk/by-id/ata-VBOX_HARDDISK_VB4e22b7b1-3df6870d-part3) while my disks have 2 partitions or less and swap is a LVM LV at /dev/system/swap. Fixing that at /etc/default/grub and updating grub.cfg fixes the problem. In summary (for this particular bug report): 1) Since the bcache tools seem to not follow symlinks, libstorage-ng should follow call them with the proper file name (or with any flag that makes the tools follow the symlinks). 2) yast2-bootloader should not write the wrong (non-existing) device into /etc/default/grub:GRUB_CMDLINE_LINUX_DEFAULT -- You are receiving this mail because: You are on the CC list for the bug.

I just notice package bcache-tools-1.1.0 is in Tumbleweed already, which includes the fix to follow symbolink. Hmm, should we close this report ? -- You are receiving this mail because: You are on the CC list for the bug.

In general, I agree with closing it as it is, but... there is no plan to release it as a maintenance update or even a installer update for SLE-15-SP1? It was originally reported for Leap 15.1 and we may get similar reports from customers doing similar tests with SLE-15-SP1 in a near future. -- You are receiving this mail because: You are on the CC list for the bug.

SLE15-SP1 is released for a while, I guess product team won't update the package version. But I can do a backport for SLE12-SP4/SLE12-SP5/SLE15-SP1/SLE15-SP2. So let's keep this report open, until the backport packages are accepted into our products. -- You are receiving this mail because: You are on the CC list for the bug.

bcache-tools for SLE12-SP4 and SLE12-SP5 are based on bcache-tools-0.1.g71, too far from 1.0.9. So the backport will be only for SLE15-SP1 and SLE15-SP2.
