Ubuntu 18.04 kernel 5.4 btrfs bug prevents btrbk from running #352

Open protree opened 3 years ago

protree commented 3 years ago

Just wanted to inform other users of btrbk that there is currently a bug in Ubuntu 18.04 with kernel 5.4 that prevents btrbk from running because of sporadic segfaults on "btrfs subvolume list", which is still unfixed. Btrbk then fails on affected drives with log message:

!!! Target "/mnt/mountpoint" aborted: Failed to fetch subvolume detail

Bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901755

Workaround: Install current mainline kernel (Description: https://wiki.ubuntu.com/Kernel/MainlineBuilds)

According to the bug report, this is now fixed upstream. Can you confirm this?

Sorry I can’t tell, I‘m not on 18.04 any more...

Same here. I consider Ubuntu versions older than 20.04 unsuitable for btrfs because it's got radically less buggy in the last couple of years.
