While developing the change that I posted in koverstreet/bcachefs-tools#245 I ran into the following:

This is a virtualbox test environment. The FS has no data on it. I was simply working on getting a multi-device bcachefs to mount at boot via an entry in the fstab. I still have the 2 virtual disk drives which comprise the FS and which I'm unable to mount. I have other virtual disks that I'm using at the moment, and those are all still working with repeated mount/unmount/reboots.

Notes:

  • F39 - current kernel
  • Latest bcachefs-tools built against util-linux release candidate

Are you still able to reproduce this? Sorry for the long delay; just got through a whole bunch of urgent repair code.

We'll want to look at journal transactions for that bucket, command to start with would be
bcachefs list_journal -a -t alloc:1:0

bcachefs list_journal -a -t alloc:1:0

As requested. Let me know if you need anything else.

I was able to get the FS to mount after a fsck, see full output below
