This patch is removing some of the "tier" code in dht xlator, as it is no longer being used. Not all of the not-needed code is removed at once, so reviewing is easier. Follow up patches removing additional unused code will follow. This is based in the work done in https://review.gluster.org/#/c/glusterfs/+/23935/ Change-Id: I3cb6a0c5d8f14afcd87cf021ef8f74b91c0f908a updates: #1097 Signed-off-by: Barak Sason Rofman <bsaonro@redhat.com>
When bringing back a downed brick and performing lookup from the client side, the permission on said brick aren't updated on the first lookup, but only on the second. This patch modifies permission update logic so the first lookup will trigger a permission update on the downed brick. LIMITATIONS OF THE PATCH: As the choice of source depends on whether the directory has layout or not. Even the directories on the newly added brick will have layout xattr[zeroed], but the same is not true for a root directory. Hence, in case in the entire cluster only the newly added bricks are up [and others are down], then any change in permission during this time will be overwritten by the older permissions when the cluster is restarted. fixes: #999 Change-Id: Ieb70246d41e59f9cae9f70bc203627a433dfbd33 Signed-off-by: Barak Sason Rofman <bsasonro@redhat.com>
Support for gluster volume heal <volname> info healed/heal-failed was removed by commit bb02cfb56ae08f56df4452c2b948fa962ae1212b in release-3.6. cli parser will display the usage message in all the supported versions whenever these clis are run, leading to some dead code in the latest branches. Since support for these clis were removed long back, this should not give any backward compatibility issues as well. Hence removing the dead code from the code base which will lead to better code coverage by the regression runs as well.

...if pending xattrs are zero for all children. Problem: If there are no pending xattrs and a metadata heal needs to be performed, it can be possible that we end up with xattrs inadvertendly deleted from all bricks, as explained in the BZ. Fix: After picking one among the sources as the good copy, mark pending xattrs on all sources to blame the sinks. Now even if this metadata heal fails midway, a subsequent heal will still choose one of the valid sources that it picked previously.

Currently even though gf_defrag_fix_layout fails with ENOENT or ESTALE, a subsequent call is made to gf_defrag_process_dir leading to rebalance failure. fixes: #1102 Change-Id: Ib0c309fd78e89a000fed3feb4bbe2c5b48e61478 Signed-off-by: Susant Palai <spalai@redhat.com>
Current implementation assumes that ping-event will come after connect event but that may not be the case in the cases where after socket connection fds need to be re-opened which would consume more time. So handle any order of the ping/child-up events. fixes: bz#1800583 Change-Id: I6bcdc0caa503bdc039ef2b4739fbf4afae121f05 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

The was a problem when self-heal was sending lookups at the same time that one of the bricks was coming up. In this case there was a chance that the number of 'up' bricks changes in the middle of sending the requests to subvolumes which caused a discrepancy in the expected number of replies and the actual number of sent requests. This discrepancy caused that AFR continued executing requests before all requests were complete. Eventually, the frame of the pending request was destroyed when the operation terminated, causing a use- after-free issue when the answer was finally received. In theory the same thing could happen in the reverse way, i.e. AFR tries to wait for more replies than sent requests, causing a hang.
