uptime for a server <=> security or stability. Long uptimes also means
a lot of active kernel bugs fixed in more resent kernels.

For your claim of been able to recover a node from crash quickly as a
consequence of using ZFS this can be easily achieved with the current
default install of Proxmox when sticking to these three rules:

1) A node is simply used as runtime for VM's/CT's.
2) All virtual disks for VM's/CT's resides on shared storage.
3) Backups are stored on shared storage as well.

Then to recover a node is simply a matter of reinstall from backup.
