I recently set up proxmox on a Dell T420. Proxmox is installed to the dual redundant 16gb SD cards, and I have a ZFS pool consisting of 4 3 tb drives in raidz where everything else is going to live.

When I add the zfs filesystems to Proxmox, the upload button is live for a moment, then greys out. I can't upload disk images or create vms. What did I do wrong?

Code:
root@pve:~# zfs list -r mypool
NAME         USED  AVAIL  REFER  MOUNTPOINT
mypool       854K  7.65T   140K  none
mypool/ISO   140K  7.65T   140K  /mnt/ISO
mypool/VMs   140K  7.65T   140K  /mnt/VMs

To upload ISO and LXC templates, you need a directory so you should add a storage as Directory

I'm pretty sure the storage has a directory. when I df -h i have

Code:
root@pve:/mnt# df -h

udev                   24G     0   24G   0% /dev

Yes, zfs assign a directory to every zvol, however in pve storage.conf you don't have have defined them, in fact you have

zfspool: ISO
pool mypool/ISO
content rootdir,images
nodes pve
sparse 0
If you want a storage dir, you have to add it as directory (in Datacenter - Storage - Add choose directory)

Thanks all. Now I'm wondering: Where are my VM's going when I have ZFS pool mypool/VMs chosen for the storage. If I browse that via SSH i see no vm's. how do i know where my vms' are living?

OK. I see this now:

Code:
> zfs list                                                                ~@pve
NAME                       USED  AVAIL  REFER  MOUNTPOINT
mypool                     181G  7.48T   140K  none
mypool/ISO                5.76G  7.48T  5.76G  /mnt/ISO
mypool/VMs                 175G  7.48T   140K  /mnt/VMs
mypool/VMs/vm-100-disk-1  72.2G  7.54T  4.90G  -
mypool/VMs/vm-101-disk-1   103G  7.56T  13.8G  -
If mypool/VMs is mounted to /mnt/VMs, why don't the disks show there?

Zfs can directly provide a volume (block device) to be used as disk for virtual machines. You can't see files because there is no file
