Hi guys. Ive been using gluster for a while now and despite a few hiccups, i find its a great system to use. One of my more persistent hiccups is an issue with one brick going offline.
My setup is a 2 brick 2 node setup. my main brick is gfs1 which has not given me any problem. gfs2 however keeps going offline. Following http://www.gluster.org/pipermail/gluster-users/2014-June/017583.html temporarily fixed the error but the brick goes offline within the hour.
This is what i get from my volume status command :
sudo gluster volume statusStatus of volume: gfsvolume
Gluster process Port Online Pid
------------------------------------------------------------------------------
Brick gfs1:/export/sda/brick 49153 Y 9760
Brick gfs2:/export/sda/brick N/A N 13461
NFS Server on localhost 2049 Y 13473
Self-heal Daemon on localhost N/A Y 13480
NFS Server on gfs1 2049 Y 16166
Self-heal Daemon on gfs1 N/A Y 16173
Task Status of Volume gfsvolume
------------------------------------------------------------------------------
There are no active volume tasks
doing sudo gluster volume start gfsvolume force gives me this:
sudo gluster volume statusStatus of volume: gfsvolume
Gluster process Port Online Pid
------------------------------------------------------------------------------
Brick gfs1:/export/sda/brick 49153 Y 9760
Brick gfs2:/export/sda/brick 49153 Y 13461
NFS Server on localhost 2049 Y 13473
Self-heal Daemon on localhost N/A Y 13480
NFS Server on gfs1 2049 Y 16166
Self-heal Daemon on gfs1 N/A Y 16173
Task Status of Volume gfsvolume
------------------------------------------------------------------------------
There are no active volume tasks
half an hour later and my brick goes down again.
This is my glustershd.log. I snipped it because the rest of the log is a repeat of the same error
