> Greetings all,
> We've got a 4 node cluster running RHEL 6.2. As part of the
> cluster, we've got several gfs2 filesystem. We've often noticed that
> when we reboot a single node in the cluster, the gfs2 mounts take a
> long
> time -- eventually getting the 120 second delay messages. When we
> migrated to 6.2, the default mount script echoed the filesystem being
> mounted, and we discovered that the long delays were
> filesystem-dependent. In particular, two filesystems were causing all
> of the problems, both of which had >1M files in them. We also noticed
> that dlm_recoverd on one of the other nodes accumulates a lot of time
> when this is happening. Is this expected? Are there non-ilnear
> handshaking algorithms between the mounting node and the cluster that
> are dependent on the number of files?

> Thanks in advance!
