Failed Drive

[matthew]

I have Proxmox 5.3 installed on 4 drives configured in a raid6 like array. Say one drive is throwing errors. How do I remove and replace just that single drive?

When I installed proxmox were all drives in array configured to be bootable? How can I insure the replacement is also?

i am assuming you are using zfs ? if yes see the commands under 'Administration' on https://pve.proxmox.com/wiki/ZFS_on_Linux (search for 'replace')
and https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Replacing_a_failed_disk_in_the_root_pool
