So, this looks like the bug to me: Apr 21 14:15:43 ubuntu-focal systemd-udevd[1916]: bcache0: /usr/lib/udev/rules.d/60-persistent-storage.rules:112 LINK 'disk/by-uuid/30b28bee-6a1e-423d-9d53-32c78ba5454a' Apr 21 14:15:43 ubuntu-focal systemd-udevd[1916]: bcache0: Updating old name, '/dev/bcache/by-uuid/1522715e-a390-40db-8d47-06fb728014e5' no longer belonging to '/devices/virtual/block/bcache0' Apr 21 14:15:43 ubuntu-focal systemd-udevd[1916]: bcache0: No reference left, removing '/dev/bcache/by-uuid/1522715e-a390-40db-8d47-06fb728014e5' Apr 21 14:15:43 ubuntu-focal systemd-udevd[1916]: bcache0: Handling device node '/dev/bcache0', devnum=b251:0
In Focal, the second event is valid, but 60-persistent-storage.rules has no rules that touch /dev/bcache/by-uuid; they don't even use the same ENV value ... so why would the by-uuid symlink rule in 60-persistent-storage.rules remove a link it doesn't have a rule for? -- 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/linux/+bug/1861941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
