Re: [Linux-cluster] disabling DLM and GFS kernel modules

It said something about an out of memory condition. This was logged just prior to where it would have panicked:

groupd[9639]: found uncontrolled kernel object rgmanager in /sys/kernel/dlm
groupd[9639]: local node must be reset to clear 1 uncontrolled instances of gfs and/or dlm openais[9625]: [CMAN ] cman killed by node 1 because we were killed by cman_tool or other application
fenced[9647]: cman_init error 0 111
dlm_controld[9653]: cman_init error 0 111
gfs_controld[9659]: cman_init error 111

There were 2 runaway processes related to GFS / DLM before I tried to shut it down. We had not encountered any issues like this until now. The only changes to our setup were a superficial change to some cluster services, and an upgrade of the DRBD kernel module.

Is there an easy way to disable GFS and related kernel modules if one does not need GFS? We are running the 5.1 Beta 1 version of the cluster and had a mysterious crash of the cluster suite. There were issues with the GFS and dlm modules. The kernel panicked on shutdown.

Do you have any details on the panic?
