Problem: In a situation where B1 blames B2, B2 blames B1 and B3 doesn't blame anything for entry heal, heal will not complete even though we have clear source and sinks. This will happen because while doing afr_selfheal_find_direction() only the bricks which are blamed by non-accused bricks are considered as sinks. Later in __afr_selfheal_entry_finalize_source() when it tries to mark all the non-sources as sinks it fails to do so because there won't be any healed_sinks marked, no witness present and there will be a source. Fix: If there is a source and no healed_sinks, then reset all the locked sources to 0 and healed sinks to 1 to do conservative merge.

We were not passing xattr_req when doing a name self heal as well as a meta data heal. Because of this, some xdata was missing which causes i/o errors Backport of>https://review.gluster.org/#/c/glusterfs/+/23024/ >Change-Id: Ibfb1205a7eb0195632dc3820116ffbbb8043545f >Fixes: bz#1728770 >Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> Change-Id: I740ccdbfcf2667fe4a850c12ecdc4b9eeed08293 Fixes: bz#1749352 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>

EC was ignoring lock contention notifications received while a lock was being acquired. When a lock is partially acquired (some bricks have granted the lock but some others not yet) we can receive notifications from acquired bricks, which should be honored, since we may not receive more notifications after that. Since EC was ignoring them, once the lock was acquired, it was not released until the eager-lock timeout, causing unnecessary delays on other clients. This fix takes into consideration the notifications received before having completed the full lock acquisition. After that, the lock will be releaed as soon as possible.

When eager-lock lock acquisition fails because of say network failures, the local is not being removed from owners_list, this leads to accumulation of waiting frames and the application will hang because the waiting frames are under the assumption that another transaction is in the process of acquiring lock because owner-list is not empty. Handled this case as well in this patch. Added asserts to make it easier to find these problems in future. fixes bz#1699736 Change-Id: I3101393265e9827755725b1f2d94a93d8709e923 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
Problem: In an arbiter volume configuration SHD will not send any writes onto the arbiter brick even if there is data pending marker for the arbiter brick. If we have a arbiter setup on the geo-rep master and there are data pending markers for the files on arbiter brick, SHD will not mark any data changelog during healing. While syncing the data from master to slave, if the arbiter-brick is considered as ACTIVE, then there is a chance that slave will miss out some data. If the arbiter brick is being newly added or replaced there is a chance of slave missing all the data during sync. Fix: If there is data pending marker for the arbiter brick, send truncate on the arbiter brick during heal, so that it will record truncate as the data transaction in changelog.

If a fop to create an entry fails on one of the data brick, we mark the pending changelog on the entry on brick for which it was successful. This is done as part of post op phase to make sure that entry gets healed even if it gets renamed to some other path where its parent was not marked as bad. As it happens as part of post op, we should consider thin-arbiter to check if the brick, which was successful, is the good brick or not. This will avoide split brain and other issues. >Change-Id: I12686675be98f02f70a5186b3ed748c541514d53 >Signed-off-by: Ashish Pandey <aspandey@redhat.com> Change-Id: I12686675be98f02f70a5186b3ed748c541514d53 updates: bz#1672314 Signed-off-by: Ashish Pandey <aspandey@redhat.com>

Problem: When quorum count option is updated, the change is not reflected in the nfs-server.vol file. This is because in get_checksum_for_file(), when the last part of the file read has size less than buffer size, the read buffer stores old data value along with correct data value. Solution: Pass the bytes read instead of fixed buffer size, for calculating checksum.
