[gpfsug-discuss] Remove a client node from one cluster and add to a different one

[Felipe Knop]

Marcy,

I believe this should work.  The mmshutdown is crucial in ensuring the operation is successful, even though mmdelnode checks to ensure the node is no longer up. I?d probably wait a few mins between the delete and the add to the other cluster, to ensure the cluster membership and config files get properly propagated.

  Felipe

Is it as simple as ? stop gpfs on client with mmshutdown mmdelnode from cluster A go to new cluster B mmaddnode and then mmstart it? This is on Linux. Wondering if anything needs to be cleaned up in /var/mmfs or /tmp/mmfs Marcy ? ? ? ? ? ? ? ? ? ? ?

mmdelnode from cluster A

go to new cluster B mmaddnode and then mmstart it?

This is on Linux.   Wondering if anything needs to be cleaned up in /var/mmfs or /tmp/mmfs
