Bug#934218: cdrom: grub-install fails with "failed to get canonical path of /dev/nvme0np1"
Package: cdrom
Severity: important
Tags: d-i
-- System Information:
Debian Release: 9.9
APT prefers oldstable
APT policy: (500, 'oldstable')
Architecture: amd64 (x86_64)
Foreign Architectures: i386
Kernel: Linux 4.9.0-9-amd64 (SMP w/8 CPU cores)
Locale: LANG=ca_ES.UTF-8, LC_CTYPE=ca_ES.UTF-8 (charmap=UTF-8), LANGUAGE=ca:en_US:es:en_GB (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash
Init: systemd (via /run/systemd/system)
Since the problem prevents me from installing the system, I'm writing the bug report from another system, so the automatically gathered data above is not correct.
The correct values (those that I know) are:
Debian Release: 10.0
Architecture: amd64 (x86_64)
Kernel: Linux 4.19.0-5-amd64
I'm trying to install Debian Buster on a system with 1 500GB NVMe disk (intended to be the system and boot disk) and 4 12TB disks intended to store data.
When partitioning the NVME disk, I create a 1GB EPS partition and a 1GB grubbios partition. The rest of the disk is configured as a RAID1 partition (it will only have one component, but I may be able to add a second disk later, so I prefer configuring it as a RAID from the beginning). The RAID partition is then configured as an LVM physical volume which ends as the only physical volume of a LVM volume group, which is further partitioned into several logical volumes to be mounted on some system directories (/, /tmp, /usr, /var, swap, ...).
The 4 12TB disks are partitioned with just one Linux raid partition, and the 4 of them are configured as a RAID6 device, that again is configured as an LVM physical volume which ends as the only component of another volume group, with just one logical volume.
The whole installation seems to work flawlessly, but when installing the grub boot loader, I get the error:
grub-install dummy failed
In the syslog, I can find the message
grub-install: error: failed to get canonical path of `/dev/nvme0n1p1`
Executing manually:
chroot /target grub-install --force "dummy"
results in exactly the same message. As a result, I am unable to install the system.
This bug seems to have appeared in some Ubuntu forums, and there is a sort of workaround in this comment:
https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1507505/comments/25
but I would prefer avoiding creating the eps partition on the 12TB disks (I would have to do that on all the disks to keep the raid partitions the same size).
Regards,
Josep Guerrero
