[SOLVED] replacing an rpool disk , question on grub-install

[RobFantini]

Hello

I replaced a disk in an rpool. Per my notes the last step is to run this on the new disk::

grub-install /dev/nvme0n1

However that returned:

grub-install is disabled because this system is booted via proxmox-boot-tool, if you really need to run it, run /usr/sbin/grub-install.real

Is grub-install still needed these days for a replaced rpool disk?

I am having trouble with the 2ND step.

here is the disk layout:

# fdisk -l /dev/nvme0n1
Disk /dev/nvme0n1: 894.25 GiB, 960197124096 bytes, 1875385008 sectors
Disk model: Micron_7450_MTFDKBA960TFR               
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 262144 bytes
I/O size (minimum/optimal): 262144 bytes / 262144 bytes
Disklabel type: gpt
Disk identifier: 7CB0D5D6-A5E1-49FD-B77D-9810D431CA09

Device           Start        End    Sectors   Size Type
/dev/nvme0n1p1      34       2047       2014  1007K BIOS boot
/dev/nvme0n1p2    2048    1050623    1048576   512M EFI System
/dev/nvme0n1p3 1050624 1562824334 1561773711 744.7G Solaris /usr & Apple ZFS

first seems Okay:

# proxmox-boot-tool format /dev/nvme0n1p2
UUID="" SIZE="536870912" FSTYPE="" PARTTYPE="c12a7328-f81f-11d2-ba4b-00a0c93ec93b" PKNAME="nvme0n1" MOUNTPOINT=""
Formatting '/dev/nvme0n1p2' as vfat..
mkfs.fat 4.2 (2021-01-31)
Done.

then:

# proxmox-boot-tool init  /dev/nvme0n1p2
Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..
UUID="" SIZE="536870912" FSTYPE="" PARTTYPE="c12a7328-f81f-11d2-ba4b-00a0c93ec93b" PKNAME="nvme0n1" MOUNTPOINT=""
E: '/dev/nvme0n1p2' has wrong filesystem (!= vfat).

strange that the 1st step shows 'Formatting '/dev/nvme0n1p2' as vfat..' .


then proxmox-boot-tool init : E: '/dev/nvme0n1p2' has wrong filesystem (!= vfat).


what am I doing wrong?

I think there was probably a glitch due to not following the documentation . i ended up using

/usr/sbin/grub-install.real  /dev/nvme0n1

.

I'll mark this closed

There must be something not in the docs for us old legacy guys with no 512 partition. Just went thru the same adventure I posted in this thread.. https://forum.proxmox.com/threads/proxmox-boot-tool-resize-or-go-back-to-grub.139682/

I just now ran the same command to get the system back running..
/usr/sbin/grub-install.real /dev/sdg
/usr/sbin/grub-install.real /dev/sde

Hello. Can you confirm me that if Proxmox is installed on Legacy BIOS I should run /usr/sbin/grub-install.real on each disk ?

I did this through several upgrades and in fact run it on all drives upon "any" upgrades. Worked so far for me. However, I've just begun wiping the systems and reinstalling for the first time in years as there were some other things to do as well...
