Hello Team, I have several clusters on KVM and we are using ISCSI as a shared storage. We have built PCS cluster with GFS2 file system. We have been troubling since 2-3 days and my shared mouth point is going in I/O error. It happens very randomly, sometime it shows I/O error on 1 hosts and sometimes on multiple hosts. We have mounted 2-3 LUN on KVM hosts and it randomly occurs on any of the mount points. It works after running the command i.e fsck.gfs2 /dev/mapper-x/vol-x. But I/O error occurs on any of the hosts after some time.
Can someone share experiences on PCS with GFS2 ? is it worth using it or not What we have observed so far that adding Shared LUN on KVMs hosts via PCS cluster is very complex and messy and it requires so hell lot of configuration while adding a simple LUN on KVM hosts. Do we other atlernatives if we have only ISCSi as primary storage. Vivek Kumar
