Converting from dlm to lock_nolock?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
I am in the process of migrating a lot of data off of a 2-node GFS2 cluster (RHEL5) via rsync. There isn't a lot of data (only about 500GB), but there are a *lot* of files (about 5.4 million inodes). As such, secondary rsync runs still take a lot of time walking the GFS2 file system tree looking for differences. I'm exploring some options for speeding that up -- the main one being dropping my cluster to only one node. Is this doable for a file system that was greated with the dlm lock manager instead of lock_nolock? Perhaps simply failing one node out of the cluster would be sufficient? I imagine some cluster.conf changes might be necessary? I am less concerned about maintaining resiliency in the cluster than I am in reducing the downtime when I shut the current live server off, do a final rsync and bring the new service online.
