Hi
Our setup looks like:
- 2 clusters in 2 different site connected with 10GBit LAN
- Storage based on FC SAN replicated on both site and available for both
site (The LUNs are available over 4 pathes, 2 from each site)
My observation:
In case one site goes down and this site owned SPM is it not possible to
move or force SPM on the second site.
It could be a sanlock issue.
The SPM uses sanlock on the storage domain, so once the SPM host will
be rebooted and sanlock will be released from the storage domain (IINM
after 80 seconds) another Host can obtain a lock on that storage
domain and become the new SPM.
What is the message in the logs that you get when you try to do that?
On the site which is down it's possible to reset all VMs that
crashed using
the "Confirm Host rebooted" menu on the oVirt Host but this does not reset
SPM.
The only solution I found was to bring the Host which owned SPM up again to
be able to move it to the other site and then reactivate the storage
domains.
I would try to attach the storage domain ( detach it first if it is
already attached) so you could register any VMs/Templates/Disks that
were added in the original env.
Is this a normal behavior?
Is there any way to force SPM reelection ?
Thanks for your help or idea...
Regards,
Arsène
