I followed what you did and i was able to get my rpool SSD disk 2 - sdb back up again! I destroyed rpool sdb on purpose by fdisk D, W and left only my Proxmox sda working. I was going to do a fresh install but this worked for me perfectly but only after a reboot. I used the same exact disk I destroyed. (This really helped me with partitions #sgdisk /dev/sda -R /dev/sdb,) #sgdisk -G /dev/sdb, #cfdisk /dev/sdb, #cfdisk /dev/sda (perfectly compared and matched partitions afterwards) I had some weird checksum errors and was able to clean them #zpool clear rpool scsi-35000c500302XXXX-part3. Looks like I learned something. Thanks

[@kras_mazov]

This is pretty scary stuff. I'm not having failing drives yet, but is there some way to prepare by making it more foolproof? Some scripts or tools, perhaps?

[@matthiasdiehl4305]

Hi Chriz, thanks for the video. I will try it tomorrow and let you know if everything worked :)

[@DoozyBytes]

dont forget to do 'zpool online -e rpool /dev/disk/by-id/ ... ' if not your zpool will not autoexpand even if set to autoexpand

[@sysopstv]

it won´t autoexpand if any partition is behind. if its not autoexpanding anyway, try to reboot for a new import

Disk klonen: sgdisk /dev/sda -R /dev/sdc sgdisk -G /dev/sdc Bootmanager neu installieren: proxmox-boot-tool format /dev/sdc2 --force proxmox-boot-tool init /dev/sdc2 --force proxmox-boot-tool status bei mir zeigt es jetzt eine Platte mit grub an anstatt alle 3 mit uefi, was hat das zu bedeuten? 3E20-2A29 is configured with: uefi 3E20-6D08 is configured with: uefi DFC0-DBD0 is configured with: grub

Proxmox's is booting from a mirror pool located in 3rd partition of each disk. However Proxmox is only allocating some 10+ GB of OS files. How can I efficiently use the available disk space of partition 3?

[@sysopstv]

First and Second is Grub/EFI Image, Third Partition is the OS and Datastore on ZFS

[@74cmonty]

@@sysopstv Understood, but that means I have ISO, templates etc. on a mirror disk although I don't need this data to be redundant because I can download ISO, templates, etc. at any time.

[@santoshshanker7305]

it is bios boot -- blue screen

[@santoshshanker7305]
