Description Kotresh HR 2018-05-28 05:36:10 UTC
Description of problem:
Changelogs are not capturing renames and hence dependant applications like geo-rep and glusterfind are failing.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set distributed gluster volume
2. Enable changelog
3. Mount the volume and do rename of a file
4. Check the backend changelog for the rename record.

Actual results:
Rename is not getting recorded by changelog

Expected results:
Rename should be recorded by changelog.

Additional info:
    The changelog would journal the rename of files only when the DHT sends a special key on the hashed subvol. The key is not being set.

Comment 2 Kotresh HR 2018-05-28 07:03:38 UTC
This is happening only one single dht subvolume. There is a new change in DHT which just does default rename if there is single subvol and this missed the changelog key to be set in xdata.

COMMIT: https://review.gluster.org/20093 committed in master by "Kotresh HR" <khiremat@redhat.com> with a commit message- cluster/dht: Fix rename journal in changelog

With patch [1], renames are journalled only
on cached subvolume. The dht sends the special
key on the cached subvolume so that the changelog
journals the rename. With single distribute
sub-volume, the key is not being set. This patch
fixes the same.

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-5.0, please open a new bug report.

glusterfs-5.0 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
