Hi all:
I had an unplanned power outage (generator failed to start, power failure lasted 3 min longer than UPS batteries). One node didn't survive the unplanned power outage.
By that, I mean it kernel panic's on boot, and I haven't been able to capture the KP or the first part of it (just the end), and so I don't truely know what the root cause is. I have validated the hardware is just fine, so its got to be an OS corruption.
Based on this, I was thinking that perhaps the easiest way to recover would simply be to delete the host from the cluster, reformat and reinstall this host, and then add it back to the cluster as a new host. Is this in fact a good idea? Are there any references to how to do this (the detailed steps so I don't mess it up)?
My cluster is (was) a 3 node hyperconverged cluster with gluster used for the management node. I also have a gluster share for VMs, but I use an NFS share from a NAS for that (which I will ask about in another post).
Thanks for the help!
