grub-probe -t abstraction /usr
show only:
lvm
and not something like this:
cryptodisk
luks
...
lvm
the OS is: Debian testing, the version of grub-probe is: (GRUB)
2.06-7
the relevant part of the filesystem looks like this (with lsbkl):
nvme0n1 259:0 0 953.9G 0
disk
├─nvme0n1p1 259:1 0 487M 0
part /boot/efi
├─nvme0n1p2 259:2 0 954M 0
part /boot
└─nvme0n1p3 259:3 0 952.5G 0
part
└─nvme0n1p3_crypt 254:9 0 952.4G 0
crypt
├─vg0-usr 254:10 0 39.8G 0
lvm /usr
calling 'grub-probe -t abstraction /usr' with a SSD works fine:
cryptodisk
luks
gcry_rijndael
gcry_rijndael
gcry_sha256
lvm
layout at that computer:
sda 8:0 0 476.9G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
├─sda2 8:2 0 244M 0 part /boot
└─sda3 8:3 0 476.2G 0 part
└─sda3_crypt 253:0 0 476.2G 0 crypt
├─vg0-usr 253:2 0 23.6G 0 lvm /usr
