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 status > > Status 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 status > > Status 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.
