ZFS Pool

[camilohto]

Hello there

I have two or three servers to do virutalization with Proxmox. Two of them are unused but the other one has some virtual machines in vmware. My intention is to have high availability using the internal storage of each server and having ZFS file systems. My question is this:

To do the initial installation, do I have to have all three servers available? Or I can do the Proxmox installation on one or two of them, pass the virtual machines that I have in vmware and, after that, incorporate the third server.

Thank you

ZFS shouldn't be that great as a HA VM storage because it can't be shared. You can setup a replication but if one server goes down you will always loose some data because the 3 servers can't be in perfect sync. If you want the advanced features like with ZFS but a storage that actually can be shared you should look if CEPH might be an option for you.
