Quoting "Buterbaugh, Kevin L" <kevin.buterba...@vanderbilt.edu>:
Hi Jaime,
Have you tried wiping out /var/mmfs/gen/* and /var/mmfs/etc/* on the
old nodeA?
Kevin
That did the trick.
Thanks Kevin and all that responded privately.

Dear group
I'm trying to deal with this in the most elegant way possible:
Once upon the time there were nodeA and nodeB in the cluster, on a
'onDemand manual HA' fashion.
* nodeA died, so I migrated the whole OS/software/application stack
from backup over to 'nodeB', IP/hostname, etc, hence 'old nodeB'
effectively became the new nodeA.
* Getting the new nodeA to rejoin the cluster was already a pain,
but through a mmdelnode and mmaddnode operation we eventually got
it to mount gpfs.
Well ...
* Old nodeA is now fixed and back on the network, and I'd like to
re-purpose it as the new standby nodeB (IP and hostname already
applied). As the subject say, I'm now facing node identity issues.
From the FSmgr I already tried to del/add nodeB, even nodeA, etc,
however GPFS seems to keep some information cached somewhere in the
cluster.
* At this point I even turned old nodeA into a nodeC with a
different IP, etc, but that doesn't help either. I can't even start
gpfs on nodeC.
Question: what is the appropriate process to clean this mess from
the GPFS perspective?
I can't touch the new nodeA. It's highly committed in production already.
Thanks
Jaime
