[SOLVED] zfs zpool not showing in webUI, but fine in shell

[p3ter_b]

Hi everyone

I've created a 200 TB zpool "tank" on the commandline. Works fine and is reboot-safe.
However, it does not show up in the proxmox web-UI (in the left "Datacenter"-tree view).

Another zpool "ma1" I've created with the web-UI, shows up nicely.

Where does pve UI store which pools it lists, and how can I fix this?

Grateful for any suggestions.

Proxmox does not automatically check for filesystems (that you create using command-line tools or otherwise). Go to Datacenter -> Storage and click Add and then ZFS. There you can select your new ZFS pool and give it a name and tell PVE how you would like to use it.

EDIT: You can also manually edit /etc/pve/storage.cfg or use the command-line: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_using_the_command_line_interface

thank you @leesteken !
Worked perfectly!

ID: tank
ZFS POOL: tank

It should actually show up in node > Disks > ZFS. I'd recommend you enable the Thin provision option when adding it as storage. It's named a bit counter intuitive but it affect the refreservation property preventing you from over-allocating storage and easily seeing the "real" used storage. This is a default option when installing with ZFS.

@Impact : Thanks for the tip regarding `thin provision`. I know about that from LVM, but hadn't related that term for ZFS.
