Hallo Philipp, seems, your nodes can not clearly communicate ?!? ..
can you check , that gpfs.gskit is at the same level ..if not, .... pls update to the same level
I've seen similar behavior , when reverse lookup of host names / wrong entries in /etc/hosts ... is breaking you setup ..
if DNS and gskit is correct... please open a PMR

Hello,
we have a gpfs v4 cluster running with 4 nsds and i am trying to add
some clients:
mmaddnode -N hpc-storage-1-ib:client:hpc-storage-1
this commands hangs and do not finish
When i look into the server, i can see the following processes which
never finish:
root 38138 0.0 0.0 123048 10376 ? Ss 11:32 0:00

/var/mmfs/ssl/stage/tmpKeyData.mmremote.38169.priv --out
/var/mmfs/ssl/stage/tmpKeyData.mmremote.38169.keystore --fips off
The node is an AMD epyc.
Any idea what could cause the issue?
ssh is possible in both directions and firewall is disabled.
Kind regards
Philipp Rehs
