I'm having similar issues to this bug and those described by Dmitrii in https://bugs.launchpad.net/charm-ceph-osd/+bug/1883585 specifically comment #2 and the last comment.
It appears that if I run 'udevadm trigger --subsystem-match=block', I get my by-dname devices for bcaches, but if I run udevadm trigger w/out a subsystem match, something is triggering later than the block subsystem that is removing the links. Here are the runs with --verbose to show what appears to be getting probed on each run: https://pastebin.ubuntu.com/p/VPvSKRfGt4/ This is with 5.3.0-62 kernel on Bionic. I also have core and canonical-livepatch snaps installed as did the environment where Dmitrii has run into this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
