Subject: [PATCH manager 0/1] pve8to9: warn about an unmounted ESP
Date: Mon, 21 Sep 2026 15:26:03 +0200 [thread overview]
Message-ID: <20260921132604.303143-1-s.rufinatscha@proxmox.com> (raw)
A UEFI system may fail to boot after upgrading from PVE 8 to PVE 9
if its EFI System Partition (ESP) was not mounted at /boot/efi during
the GRUB update [0].
Warn if /boot/efi is not mounted on a UEFI system. Ask the user to
mount it before upgrading and to make sure it mounts at boot. Skip
systems managed by proxmox-boot-tool, which mounts the ESPs itself.
Testing:
Tested the patched pve-manager package on a PVE 8 VM that was updated
to the latest packages from the enterprise repository. The ESP warning
appeared with /boot/efi unmounted and was no longer shown after mounting
it.
