Here's the scenario:
- local NSD cluster with 7 manager nodes serving filesystem fs0.
- remote GPFS cluster mounting cluster fs0.
I'd like to set a callback when a softQuota violation is detected. I've done all of the dirty work, and verified things are called appropriately, but I have a question about which nodes to run this on.
Since this type of callback is a local event, which nodes should it be running on?
From The Fine Manual:
: Triggered when the file system manager detects that a user or fileset quota has been exceeded.
So if a user on a remoteCluster exceeds their soft quota, should this callback be set on ALL of the local NSD cluster manager nodes (-N managernodes), or just the filesystem manager node (from mmlsmgr)?
If the primary filesystem manager node (from mmlsmgr) goes down, does the callback need to be moved?
I guess I'm just not fully understanding the significance of 'local' callbacks with which node the callback would indeed be local to.
Thanks in advance.
