btrfs: could not do orphan cleanup -22

[Reartes Guillermo]

I booted the guest in which i was testing btrfs (transient ENOSPC
issues, etc). It booted in emergency mode.

I tried to btrfsck sdb1, the first time it

hecking extents
checking fs roots
checking root refs
found 23233744896 bytes used err is 0

Btrfs Btrfs v0.19

Since sda2 is mounted i could not check it, but from the logs it is
not clear to me if the issue is in sda2 or sdb1.

maybe the error should be something like that:
btrfs: sdaX: Error XXXXXX

I intend to reinstall the guest, since it is for testing purposes
(btrfs testing)

I booted first with 3.8.0-0.rc3.git1.1.fc19 (which has a lot of
issues) and then back with 3.7.2-201.fc18.

Cheers.

Seems sda2 from the above.

The orphan cleaning messages are harmless (and not useful to users
anyway), not like the failed mount. As a workaround, mount it read-only
and remount read write. It should be fixed after first mount cycle.

We've seen the -22 error during testing and Josef is aware of that, so
it's going to be fixed after the checksum problems.

I don't see from the messages under which kernel it happened, but I
assume with both.
