This patch limits itself to only handling the case where no file (data or linkto) exists on the subvol. Additional cases to be handled: 1. A linkto file was found on the only child subvol. This currently calls dht_lookup_everywhere which eventually deletes it. It can be deleted directly as it will not be pointing to a valid subvol. 2. Directory lookups - locking might be unnecessary in some cases. > Change-Id: I940ba34531f2aaee1d36fd9ca45ecfd46be662a4 > BUG: 1546620 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I940ba34531f2aaee1d36fd9ca45ecfd46be662a4 BUG: 1548271 Signed-off-by: N Balachandran <nbalacha@redhat.com>

With Gluster 4.0 we will not provide the server components for EL6 and older. At one point Gluster 4.x will get GlusterD2, which requires Golang tools in the distribution. EL6 does not contain these at the moment. With this change, it is possible to `./configure --without-server` which prevents building glusterd and the xlators for the bricks. Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

With brick multiplexing, to attach a brick to an existing brick process
the prerequisite is to have the compatible brick to finish it's
initialization and portmap sign in and hence the thread might have to go
to a sleep and context switch the synctask to allow the brick process to
communicate with glusterd. In normal code path, this works fine as
glusterd_restart_bricks () is launched through a separate synctask.
In case there's a mismatch of the volume when glusterd restarts,
glusterd_import_friend_volume is invoked and then it tries to call
glusterd_start_bricks () from the main thread which eventually may land
into the similar situation. Now since this is not done through a
separate synctask, the 1st brick will never be able to get its turn to
finish all of its handshaking and as a consequence to it, all the bricks
will fail to get attached to it.
Solution : Execute import volume and glusterd restart bricks in separate
synctask. Importing snaps had to be also done through synctask as
there's a dependency of the parent volume need to be available for the
importing snap functionality to work.

With https://review.gluster.org/#/c/12363/ being merged, we no longer send client's lk-version to server side and the corresponding check on server is also removed. But when clients are upgraded prior to servers, the check for lk-version at server side fails and is reported back to clients resulting in disconnection. Since we don't have lock-recovery (lk-version and grace-timeout) logic anymore in code base our best bet would be to add client's default lk-version i.e, 1, into the dictionary just to make server side check pass and continue with remaining SETVOLUME operations.

tier-enabled flag in volinfo structure was introduced in 3.10, however while writing this value to the glusterd store was done with a wrong op-version check which results into volume checksum failure during upgrades. >Change-Id: I4330d0c4594eee19cba42e2cdf49a63f106627d4 >BUG: 1544600 >Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Change-Id: I4330d0c4594eee19cba42e2cdf49a63f106627d4 BUG: 1544638 Signed-off-by: hari gowtham <hgowtham@redhat.com>
Non-privileged users cannot delete linkto files. However the failure to unlink a stale linkto causes DHT to fail the lookup with EIO and hence prevent access to the file. > Change-Id: Id295362d41e52263790694602f36f1219f0646a2 > BUG: 1542318 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: Id295362d41e52263790694602f36f1219f0646a2 BUG: 1543487 Signed-off-by: N Balachandran <nbalacha@redhat.com>
Because of some crazy race in volume start code path because of friend handshaking with volumes with quorum enabled we might end up into a situation where glusterd would start a brick and get a disconnect and then immediately try to start the same brick instance based on another friend update request. And then if for the very first brick even if the process doesn't come up at the end sign in event gets sent and we end up having two duplicate portmap entries for the same brick. Since in brick start we mark the previous port as free, its better to consider a sign in request as no op if the corresponding port type is marked as free. >mainline patch : https://review.gluster.org/#/c/19263/ Change-Id: I995c348c7b6988956d24b06bf3f09ab64280fc32 BUG: 1543711 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 9d708a3739c8201d23f996c413d6b08f8b13dd90)
