Which one is not true "I had used common storage" or "On both the nodes
data is not in sync" - if it is a common storage the data is the same?

if you are using GFS2 without a cluster and dlm locking i.e. local_locking
then it is possible both to be true

GFS2 has nothing to do with syncing the data between two storages - if
that's what you are after, check DRBD

if you are using improperly configured GFS2 on a shared storage i.e.
without cluster and dlm it is no different than any other local filesystem
and corruption is guaranteed on simultaneous use

how did you create the GFS2 filesystem? Also please show your cluster.conf
and relevant storage details
