Bug 966845

Summary:	DHT - remove-brick - data loss in remove-brick because in DHT 'remove-brick start' makes hash - layout 0000000000000000 for some other brick, no migration and data written after start operation also goes to that brick so on commit it ends in data loss

Comment 7 Niels de Vos 2014-04-17 13:12:53 UTC

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-3.4.3, please reopen this bug report.

glusterfs-3.4.3 has been announced on the Gluster Developers mailinglist [1], packages for several distributions should already be or become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.

The fix for this bug likely to be included in all future GlusterFS releases i.e. release > 3.4.3. In the same line the recent release i.e. glusterfs-3.5.0 [3] likely to have the fix. You can verify this by reading the comments in this bug report and checking for comments mentioning "committed in release-3.5".
