zpool action required - zpool upgrade

[spearox]

Hello,

I recently upgraded to Proxmox 7 and checked the zpool status. Some action required.
Its safe to use zpool upgrade? If i remember correctly i started by Proxmox 5 and i got this message after upgraded to Proxmox 6. (but i ignored)

root@node1:~# zpool status
  pool: rpool
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Its safe to use zpool upgrade? If i remember correctly i started by Proxmox 5 and i got this message after upgraded to Proxmox 6. (but i ignored)

This depends on how the system is booting (if proxmox-boot-tool is used) - see
https://pve.proxmox.com/wiki/ZFS:_Switch_Legacy-Boot_to_Proxmox_Boot_Tool

and
https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysboot_determine_bootloader_used

I hope this helps!

I'll use the proxmox-boot-tool way to boot.

I'll use the proxmox-boot-tool way to boot.

If this is already the case (if you're unsure post the output of `proxmox-boot-tool status`) then upgrading the zpools should not cause any issues.

As always when touching disk- and boot-related configuration - make sure you have a working backup of all your data!

I think it is but to be in safe side i'll post the output.

root@node1:~# proxmox-boot-tool status
Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..

Looks like the system indeed uses proxmox-boot-tool - I assume that you see a black-screen with the kernel-versions for booting (systemd-boot)

However - as always - make sure you have a working and tested backup of your data before changing your root-pool
