How to get disk name that contains a specific partition
You can observe in /sys
the block device for a given partition name. For example, /dev/sda1:
$ ls -l /sys/class/block/sda1
lrwxrwxrwx 1 root root /sys/class/block/sda1 -> \
../../devices/pci0000:00/.../ata1/host0/target0:0:0/0:0:0:0/block/sda/sda1
A script to take arg /dev/sda1
and print /dev/sda
is:
part=$1
part=${part#/dev/}
disk=$(readlink /sys/class/block/$part)
disk=${disk%/*}
disk=/dev/${disk##*/}
echo $disk
I don't have lvm etc to try out, but there is probably some similar path.
There is also lsblk
:
$ lsblk -as /dev/sde1
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sde1 8:65 1 7.4G 0 part
`-sde 8:64 1 7.4G 0 disk
and as @don_crissti said you can get the parent directly with:
lsblk -no pkname /dev/sda1
