Hi All, More time for gluster; after much travel in the twisty dark tunnels of OFED, IB, card firmware & upgrades, OS compatibility, etc, I now have a distributed rdma volume over 5 bricks (2 on one server) and it seems to be working well. I would now like to force-unload one brick to emulate a disk upgrade process. Here's my vol info: --------------------------- Thu Dec 08 11:44:05 [0.08 0.05 0.01] root at pbs3:~ 522 $ gluster volume info Volume Name: glrdma Type: Distribute Status: Started Number of Bricks: 5 Transport-type: rdma Bricks: Brick1: pbs1:/data2 Brick2: pbs2:/data2 Brick3: pbs3:/data2 Brick4: pbs3:/data Brick5: pbs4:/data ---------------------------
