Dear all I'm testing Gluster in a cluster of compute nodes, based on Rocks. The idea is to use the scratch of each nodes as a big volume for scratch. It permit to access to this scratch system file on all the nodes of the cluster. For the moment, i have installed this gluster system on 4 nodes, ona distributed replica of 2, like this: # gluster volume info Volume Name: scratch1 Type: Distributed-Replicate Volume ID: c8c3e3fe-c785-4438-86eb-0b84c7c29123 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: compute-2-0:/state/partition1/scratch Brick2: compute-2-1:/state/partition1/scratch Brick3: compute-2-6:/state/partition1/scratch Brick4: compute-2-9:/state/partition1/scratch # gluster volume status Status of volume: scratch1 Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick compute-2-0:/state/partition1/scratch 24009 Y 16464 Brick compute-2-1:/state/partition1/scratch 24009 Y 3848 Brick compute-2-6:/state/partition1/scratch 24009 Y 511 Brick compute-2-9:/state/partition1/scratch 24009 Y 2086 NFS Server on localhost 38467 N 4060 Self-heal Daemon on localhost N/A N 4065 NFS Server on compute-2-0 38467 Y 16470 Self-heal Daemon on compute-2-0 N/A Y 16476 NFS Server on compute-2-9 38467 Y 2092 Self-heal Daemon on compute-2-9 N/A Y 2099 NFS Server on compute-2-6 38467 Y 517 Self-heal Daemon on compute-2-6 N/A Y 524 NFS Server on compute-2-1 38467 Y 3854 Self-heal Daemon on compute-2-1 N/A Y 3860 All of this run correctly, i used some stress file to advise that configuration could be runnable. My problem is when a node reboot accidentaly, or for some administration task: the node reinstall itself, and the gluster volume begin to fail.... I detect taht the UUID of a machine is generated during the instalation, so i develop some script to get back the original UUID of the node. Despote this, the node could not get back in the volume. I miss some special task to do. So, it is possible to do a such system with gluster? or maybe i have to reconfigure all of the voluem when a node reinstall?
