Doc Type: Bug Fix
Doc Text:
Previously, DHT did not rollback directory rename operations if they did not succeed on all bricks. This resulted in duplicate directories (with both old and new names) having the same gfid on bricks where the rename operation failed. With this fix, DHT rolls back the directory rename operations if it was not successful on all the bricks.

Comment 14 Nithya Balachandran 2018-03-05 05:38:09 UTC 
As I believe the issue to be related to ACLs not being set on the new bricks,I am adding BZ# 1550315 as a dependency.
Comment 34 Prasad Desala 2018-04-20 12:11:26 UTC 
Reproduced this issue on 3.3.1 and followed the same steps for verifying this BZ on 3.4.0 (3.12.2-7.el7rhgs.x86_64).

1) Created a distributed-replicate volume and start it.
2) FUSE mount it on a client.
3) On mount point, create a directory "dir1"
4) Select a replica pair and for all the bricks in this replica pair set read-only option to on by making changes in the brick vol file. 
5) Stop and start the volume.
6) From mount point, rename the directory from dir1 to dir2.

Before fix, dir1 is not renamed on the read-only bricks and on other bricks rename is successful leading to inconsistency across the nodes and both dir1 and dir2 are having same gfid.

After fix, all the backend bricks are having the same directory.

Moving this BZ to Verified.

Hadn't this been reworded to remove all mention of DHT?
