* glusterd: delete source brick only once in reset-brick commit forceAtin Mukherjee2017-10-311-1/+1
| | | | | | | | | | | | | | While stopping the brick which is to be reset and replaced delete_brick flag was passed as true which resulted glusterd to free up to source brick before the actual operation. This results commit force to fail failing to find the source brickinfo. > mainline patch : https://review.gluster.org/#/c/18581/ Change-Id: I1aa7508eff7cc9c9b5d6f5163f3bb92736d6df44 BUG: 1507880 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 0fb8acaa6ff80c43e46deac0ce66b29ae0df0ca4)
* glusterd: Make reset-brick work correctly if brick-mux is onSamikshan Bairagya2017-05-121-46/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reset brick currently kills of the corresponding brick process. However, with brick multiplexing enabled, stopping the brick process would render all bricks attached to it unavailable. To handle this correctly, we need to make sure that the brick process is terminated only if brick-multiplexing is disabled. Otherwise, we should send the GLUSTERD_BRICK_TERMINATE rpc to the respective brick process to detach the brick that is to be reset. > Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> > Reviewed-on: https://review.gluster.org/17128 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 74383e3ec6f8244b3de9bf14016452498c1ddcf0) Change-Id: I69002d66ffe6ec36ef48af09b66c522c6d35ac58 BUG: 1449934 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17253 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
* xlators/glusterd: fix unused variable warnings/errorsKaleb S. KEITHLEY2016-09-131-7/+0
| | | | | | | | | | | | | | | | | | | | http://review.gluster.org/14085 fixes a "pragma leak" where the generated rpc/xdr headers have a pair of pragmas that disable these warnings. With the warnings disabled, many unused variables have crept into the code base. And 14085 won't pass its own smoke test until all these warnings are fixed.

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-0/+430
The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.
