Storage fencing with full NVME based setup #27

Closed cu12 closed 5 years ago

cu12 commented 5 years ago

Hi all,

I can see you use fence_scsi here, although I couldn't find any equivalent to do the same with NVME. Actually, I found that there's no fencing agent for NVME :/ https://bugzilla.redhat.com/show_bug.cgi?id=1700165

Any ideas for this?

I have a two VMs setup with physical disks presented to them for ZFS.

I'm not sure what the design of your solution is. Can you describe it in better detail?

cu12 commented 5 years ago

Hi @ewwhite I'm planning two create a simple two node setup, but instead of having scsi or ssd disks, mine are all nvme disks, where fence_scsi (or scsi equivalent translation methods) doesn't apply. Hope this made it a bit more clearer :)

How do you expect this to work?

For fencing I'm using fence_ipmilan, described here https://github.com/efschu/AP-HA-CIAB-ISER/wiki btw thanks @ewwhite for your guide, without yours mine would never have get written ;)
