Dear all,
I am running GFS 6.1 with dlm on a cluster (4 nodes + front-end) of
dual-headed Opterons and RHEL4U3. Because of some problems (kernel
panic...) I had to hard boot some nodes of the cluster. Now, some gfs
partitions won't mount. They will simply keep waiting forever for the
"join" of the GFS group:
So... three questions:
- What is the join exactly doing ? Cluster status is fine, everybody is
member ...
- What does the status code mean in the cman_tool output ?
- What can I do to restart this cluster ?
NB: Before testing this (below) I rebooted the complete cluster and
gfs_fsck'ed /all nodes /with everything unmounted.
