Hey all! To those who celebrate; Happy (day before) Thanksgiving!
I’m currently running a lab consisting of 2 XCP-ng hosts in a pool with an iSCSI SR hosted on TrueNAS. This pool currently runs 12 VMs, a few of which I would consider ‘home production’ and while it wouldn’t be the end of the world if they died or I had to rebuild them, it would be very time consuming and frustrating. Right now everything is humming along happily, but the two XCP-ng hosts are custom builds and getting old. I recently purchased two identical (used) HP servers that I plan on upgrading to.
Now for the dilemma:
I know you can’t have multiple pools connected to a single iSCSI LUN, so my thought was to shut down the old hosts, configure the new, attach the iSCSI SR to the new pool, then re-build the VMs and attach the VHDs from the SR. I know this is a niche scenario, but do you think this would work? Can anyone think of an easier way to migrate?
As stated, this is a lab only running a few ‘production’ VMs so down time isn’t a huge deal, but I would prefer not to have to rebuild from the ground up. If nothing else, I’m seeing this as a learning opportunity on how not to configure your storage for production. Hope to hear from you soon!
