[SOLVED] Remove leftover boot UEFI boot environments

[enoch85]

I recently changed the whole rpool mirror to two new disks. All went well and the new disks are now running instead (SSD--> NVME).

The problem is that I now have the old boot environments left, as they weren't removed automatically with the proxmox-boot-tool. Situation is like this:

root@pbs-offsite:~# proxmox-boot-tool status

Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..

        nvme-redacted_X300_256GB_TP2redacted-part3  ONLINE       0     0     0

errors: No known data errors

How do I find which boot environments that are in use, and how do I safely remove them?

There's no man page, but:


proxmox-boot-tool --help


Invalid/unknown command '--help'.

USAGE: /usr/sbin/proxmox-boot-tool <commands> [ARGS]

  /usr/sbin/proxmox-boot-tool format <partition> [--force]
  /usr/sbin/proxmox-boot-tool init <partition> [grub]
  /usr/sbin/proxmox-boot-tool reinit

  /usr/sbin/proxmox-boot-tool kernel list
  /usr/sbin/proxmox-boot-tool status [--quiet]
  /usr/sbin/proxmox-boot-tool help

You might try clean --dry-run and see what it recommends; I usually use efibootmgr and delete obsolete/unwanted boot entries but don't know if that applies for ZFS boot/root

Well that was an easy one:

root@pbs-offsite:~# proxmox-boot-tool clean

Checking whether ESP '3EC4-BA68' exists.. Not found!
Checking whether ESP '6211-173B' exists.. Not found!
Checking whether ESP '95D7-D59E' exists.. Found!
Checking whether ESP 'D423-C9D6' exists.. Found!

Strange because I ran clean before but it didn't change anything. Problem solved anyway. :+1:
