Hello,
Recently, I use proxmox for my company. And I have a few questions about it.

1. I use a usb device to install proxmox to servers, and when it comes to chose file system, I want to chose zfs but below the type it shows me two hard disk (one is server's disk and the other is usb) so I can not continue to next by chosing zfs file system... how can I select just my server's disk only?

2. I set up with 3 nodes as a cluster for HA, and I want to ask how can I test for HA is able to migrate VM or LXC to another node when that node is down or crash ? ( I try to reboot one of the node which already run VMs or LXCs but it only change to freeze state and wait for the node back online again then run overagain. )

3. Is it only VMs can do live migration without downtime, but LXCs can not ?

use options to select zfs...
I don't know if zfs is the right choice for an single hdd.

ha can work only with shared or distributed storage. Other nodes must be able to access the VM-hdd.

Thanks for explainning~

The last question, is it also need with shared or distributed storage so the live migration can without downtime ?

And can zfs be a distributed storage?

You can click in the second disk and choose none, so it will install only in the first disk as ZFS raid0
You are running proxmox inside VMware, is it a test environment?

I will test for chose none as second disk today... thanks for advise.

Yes, it just show you I meet with the two options when I came to this step, and the VMware just shows, I use real severs for my installation.
