http://bugzilla.opensuse.org/show_bug.cgi?id=1130273 Bug ID: 1130273 Summary: Snapper / BTRFS rollback resulting in "Segmentation fault" Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: novell@regproctor.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I installed an update to plex server with zypper as I have done many times before but in this case the server wasn't working. I tried to downgrade and it didn't do that properly. No problem, I'll just rollback the OS but when running: snapper rollback 224 I get the following: Creating read-only snapshot of current system. (Snapshot 253.) Creating read-write snapshot of snapshot 224. (Snapshot 254.) Segmentation fault (core dumped) When I looked at the version of Plex it didn't change so the rollback failed. This is critical IMHO as I'm left not knowing the state of the OS. E.g. has some of it rolled back? is it about to fail and be unbootable? and left with no way to rollback if anything else goes wrong such as things starting to compound from this problem.

I rebooted my computer with a USB and checked the file system with btrfsck and it reported no errors, I just hope that lasts. zypper lr give me: Repository priorities are without effect.
