[Gluster-users] What does this error mean?

[Burnash, James]

Does anybody have any clue as to why this is happening? The problem has persisted for several days now, but I can't find anything at all in the logs to possibly explain why this is so.

Hello.

After purposely crashing (via ' echo b>/proc/sysrq-trigger ) node jc1letgfs6 to test mirroring, even after the node has rebooted and is back online I am still seeing the statement "Disconnected" for that node when I execute the following command on the first storage node:

root at jc1letgfs5:/etc/glusterd/vols# gluster peer status
Number of Peers: 3

Hostname: jc1letgfs6
Uuid: cd590fad-022c-4b9a-97f5-3262080d772d
State: Peer in Cluster (Disconnected)

Hostname: jc1letgfs7
Uuid: c5f40de4-9bb1-47ad-93b6-d52c6689ee29
State: Peer in Cluster (Disconnected)

Hostname: jc1letgfs8
Uuid: 13f4ce3f-042e-4144-a76c-d2b1b91676bd
State: Peer in Cluster (Connected)

This is running on 4 servers with CentOS 5.5 (x86_64), GlusterFS 3.1.1

Here is the volume info:

# gluster volume info

Volume Name: test-pfs-ro1

Options Reconfigured:

Even with this error, mirroring functions as expected, and the node is recognized and utilized, as can be seen in this log fragment from jc1letgfs5: /var/log/glusterfs/etc-glusterfs-glusterd.vol.log

Any pointers or help would be appreciated.
