Title:
btrfs: regression in 3.16 with renaming of directory in between two
snapshots
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Utopic:
Fix Released
Bug description:
SRU Justification: (Utopic)
[Impact]
If between two snapshots we rename an existing directory named X to Y and
make it a child (direct or not) of a new inode named X, we were delaying
the move/rename of the former directory unnecessarily, which would result
in attempting to rename the new directory from its orphan name to name X
prematurely.
[Fix]
upstream commit bf8e8ca6fd4ac6e8edc58b92cffb2ffd51933138
"Btrfs: send, don't delay dir move if there's a new parent inode"
this is a simple one-liner, risk is low to zero.
[Testcase]
As from the commit:
$ mkfs.btrfs -f /dev/vdd
$ mount /dev/vdd /mnt
$ mkdir -p /mnt/merlin/RC/OSD/Source
$ btrfs subvolume snapshot -r /mnt /mnt/mysnap1
$ mkdir /mnt/OSD
$ mv /mnt/merlin/RC/OSD /mnt/OSD/OSD-Plane_788
$ mv /mnt/OSD /mnt/merlin/RC
$ btrfs subvolume snapshot -r /mnt /mnt/mysnap2
$ btrfs send /mnt/mysnap1 -f /tmp/1.snap
$ btrfs send -p /mnt/mysnap1 /mnt/mysnap2 -f /tmp/2.snap
$ mkfs.btrfs -f /dev/vdc
$ mount /dev/vdc /mnt2
$ btrfs receive /mnt2 -f /tmp/1.snap
$ btrfs receive /mnt2 -f /tmp/2.snap
The second receive (from an incremental send) failed with the following
error message: "rename o261-7-0 -> merlin/RC/OSD failed".
This is a regression introduced in the 3.16 kernel.
