ESS bring up the GPFS in recovery group without takeover</font><br><font size=1 color=#5f5f5f face="sans-serif">Sent by:
</font><font size=1 face="sans-serif">gpfsug-discuss-bounces@spectrumscale.org</font><br><hr noshade><br><br><br><font size=3>It's been a very frustrating couple of months with our
2 ESS systems. IBM tells us we had blueflame bug and they came on site
and updated our ESS to the latest version back in middle of November. Wednesday
night one of the NSD servers in one of our ESS building blocks kernel panicked.
No idea why and none of the logs are insightful. We have a PMR open with
IBM. I am not very confident we will get to the bottom of what's causing
kernel panics on our IO servers. The system has gone down over 4 times
now in 2 months. </font><br><br><font size=3>When we tried brining it back up, it rejoined the recovery
group and the IO on the entire cluster locked up until we were able to
find couple of compute nodes with pending state in mmfsadm dump tscomm.
Killing gpfs on those nodes resolved the issue of the filesystem locking
up.</font><br><br><font size=3>So far we have never been successful in brining back an
IO server and not having a filesystem lock up until we find a node with
pending state with tscomm. Anyway, the system was stable for few minutes
until the same IO server that went down on Wednesday night went into an
arbitrating mode. It never recovered. We stopped gpfs on that server and
IO recovered again. We left gpfs down and cluster seems to be OK.</font><br><br><font size=3>My question is, is there a way of brining back the IO
server into the mix without the recoverygroup takeover happening? Could
I just start a gpfs and have it back in the mix as a backup server for
the recoverygroup and if so, how do you do that. Right now that server
is designated as primary server for the recovery group. I would like to
have both IO servers in the mix for redundancy purposes.</font><br><br><font size=3>This ESS situation is beyond frustrating and I don't see
end in sight.</font><br><br><font size=3>Any help is appreciated.</font><tt><font size=2>_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at spectrumscale.org<br></font></tt><a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__gpfsug.org_mailman_listinfo_gpfsug-2Ddiscuss&d=DwICAg&c=jf_iaSHvJObTbx-siA1ZOg&r=IbxtjdkPAM2Sbon4Lbbi4w&m=vGabwIUw-ziMAtM7VfTppRp3S16NsgGOk5qMe50gtIQ&s=eplQuGhWVZMQ3tBLeqhCKpZ0w0rIiU-2R-UuqHYSsVA&e="><tt><font size=2>https://urldefense.proofpoint.com/v2/url?u=http-3A__gpfsug.org_mailman_listinfo_gpfsug-2Ddiscuss&d=DwICAg&c=jf_iaSHvJObTbx-siA1ZOg&r=IbxtjdkPAM2Sbon4Lbbi4w&m=vGabwIUw-ziMAtM7VfTppRp3S16NsgGOk5qMe50gtIQ&s=eplQuGhWVZMQ3tBLeqhCKpZ0w0rIiU-2R-UuqHYSsVA&e=</font></tt></a><tt><font size=2><br></font></tt><br><br><BR>
