[SOLVED] New rpool is not bootable

[damian418]

Greetings - I replaced my two sas hard drives that were in a zfs mirror with two new ssds. Everything went fine with the zpool replace and resilvering. Below is the zpool status and list.

BUT.... it is not bootable. I have to put one of the old drives back in during boot to get it to move on to GRUB and actually boot.

How do I make the new rpool bootable?

If you only did a simple "zpool replace" you now ended up without any boot partitions. Correct way would have been to clone the partition tables and syncing the bootloaders first and then doing a "zpool replace" with only the partition 3 partition of that cloned disk. See "Changing a failed bootable device" and not "Changing a failed device": https://pve.proxmox.com/wiki/ZFS_on_Linux#_zfs_administration

Awesome. Thank you very much. I followed this process and I am up and running with a bootable set of ssds!
