I've got more information on the following error :
At subvol /mnt/ArchPri/backup/primary/thinkcentre/root/backup.0.2
At snapshot backup.0.2017.04.21.03.11.40
ERROR: rename o3528-7220-0 -> usr failed: Directory not empty
I've filed a bug report with additional details at:
https://bugzilla.kernel.org/show_bug.cgi?id=195619
This error occurs during a series of "btrfs send" invocations. It does
not occur on all of them, but always at the same point in the operation,
and so appears to be specific to (dependent on) the data being sent.
I have a test case down to the following:
su -
btrfs send --no-data temp/backup.0.2017.04.17.07.57.17 | btrfs rec temp/test
sync
btrfs send --no-data -p temp/backup.0.2017.04.17.07.57.17
temp/backup.0.2017.04.21.03.11.40 | btrfs rec temp/test
The error should be something like:
At subvol temp/backup.0.2017.04.21.03.11.40
At snapshot backup.0.2017.04.21.03.11.40
ERROR: rename o3528-7220-0 -> usr failed: Directory not empty
I will probably need to provide the data somehow, or at least the output
from "btrfs send". The original data is several GB in size.
