My server died and I want to use my drives in the new computer

[GaryK4]

I have a Dell 99K5t Optiplex 3050 that died but the drives are working. I purchased an identical computer and put the old drives in the new computer, The MAC address is different of course, When booting, I get [FAILED] Failed to start zfs-import2Oldsda.service - Import ZFS pool Oldsda.
I get to the prompt and can login. I have the new MAC address and assigned it the the previous IP, However I don't see it connecting in the router.
Is what i am trying to do possible? I don't want to lose my VM's and have to recreate them.

At the pve console, do:

zpool import -a -f -d /dev/disk/by-id # If that doesnt work, try by-path

The pool(s) are likely not importing bc they were not exported properly from the old system.

You'll likely need to edit /etc/network/interfaces and correct any entries that still have the old NIC with the new NIC name, then issue:
systemctl restart networking

I have the new MAC address and assigned it the the previous IP, However I don't see it connecting in the router.

It appears you've allocated that IP in the router as an assigned address. I'd remove that address reservation in the router - reboot the router - and THEN turn on the node.
