Such problems can be "fixed" by running 'btrfs-zero-log' on the device, and this will supposedly make your filesystem mountable again but there may be some filesystem changes lost (not longer than last 30 seconds worth). Thank you for the report, I have passed it upstream, and the fix is being worked on. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'll send out a request for update, you can use the factory package in the meantime. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I looked into your log (comment 7) again and saw the same error which was reported via other bug and I'll continue there. Closing this one. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
