I have a gluster distributed volume that has been running nicely with gluster-3.2.7 for the past two years and I now want to upgrade this to gluster-3.5.0. What is the recommended procedure for such an upgrade? Is it necessary to upgrade from 3.2.7 to 3.3 to 3.4 to 3.5, or can I safely transition from 3.2.7 directly to 3.5.0?
nobody responded so i decided to wing it and hope for the best. i also decided to go directly from 3.2.7 to 3.4.3 and not bother with 3.5 yet. the volume is distributed across 13 bricks. formerly these were in 13 nodes, 1 brick per node, but i recently lost one of these nodes. i've moved the brick from the dead node to be a second brick in one of the remaining 12 nodes. i currently have this state: gluster volume status Status of volume: scratch Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick 172.16.1.1:/1/scratch 49152 Y 6452 Brick 172.16.1.2:/1/scratch 49152 Y 10783 Brick 172.16.1.3:/1/scratch 49152 Y 10164 Brick 172.16.1.4:/1/scratch 49152 Y 10465 Brick 172.16.1.5:/1/scratch 49152 Y 10186 Brick 172.16.1.6:/1/scratch 49152 Y 10388 Brick 172.16.1.7:/1/scratch 49152 Y 10386 Brick 172.16.1.8:/1/scratch 49152 Y 10215 Brick 172.16.1.9:/1/scratch 49152 Y 11059 Brick 172.16.1.10:/1/scratch 49152 Y 9238 Brick 172.16.1.11:/1/scratch 49152 Y 9466 Brick 172.16.1.12:/1/scratch 49152 Y 10777 Brick 172.16.1.1:/2/scratch 49153 Y 6461 what i want to do next is remove Brick 172.16.1.1:/2/scratch and have all files it contains redistributed across the other 12 bricks. what's the correct procedure for this? is it as simple as: gluster volume remove-brick scratch 172.16.1.1:/2/scratch start and then wait for all files to be moved off that brick? or do i also have to do: gluster volume remove-brick scratch 172.16.1.1:/2/scratch commit and then wait for all files to be moved off that brick? or do i also have to do something else, such as a rebalance, to cause the files to be moved? how do i know when everything has been moved safely to other bricks and the then-empty brick is no longer involved in the cluster? thanks, tp _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users
