Resizing Proxmox zfs pool (raid1) problem

[platini76]

hello I had two nvme disks (512gb) with a zfs pool (raid1)
I copy all them to a new 2tb disks successfully
now I have to expand volume to max available space. and this is the problem.

root@pve:~# zpool status
  pool: rpool
 state: ONLINE
  scan: resilvered 158G in 00:02:18 with 0 errors on Tue Dec 10 01:28:07 2024
config:

        rpool                                                   ONLINE       0     0     0

errors: No known data errors

how to do it without losing data?

I solved with these commands:

apt update
apt install cloud-guest-utils

growpart /dev/nvme4n1 3

partprobe /dev/nvme4n1

growpart /dev/nvme5n1 3

partprobe /dev/nvme5n1

now output is:

zpool list rpool
NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
rpool  1.82T   156G  1.66T        -         -     7%     8%  1.00x    ONLINE  -

I copy all them to a new 2tb disks successfully

You didn't mentioned this, so just to give a possibly redundant hint: make sure to create all required partitions and use "proxmox-boot-tool" to maintain "bootability" as described here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_change_failed_dev
