I had a catastrophic failure of the IB switch that was used by all my storage domains. I had one data domain that was NFS and one that was iSCSI. I managed to get the iSCSI LUN detached using the docs [1] but now I noticed that somehow my master domain went from the NFS domain to the iSCSI domain and I'm unable to switch them back.
How does one change the master? Right now I am having issues getting iSCSI over TCP to work, so am sort of stuck with 30 VMs down and an entire cluster inaccessible.
Thanks,
