I've seen the docs to create Custom Resources for Local Storage: https://docs.openshift.com/container-platform/4.5/storage/persistent_storage/persistent-storage-local.html#local-volume-cr_persistent-storage-local
But not sure how to populate the spec.storageClassDevices.devicePaths
field.
I've tried the lsblk
command in one of my nodes and got this response:
sh-4.4# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 252:0 0 250G 0 disk
|-vda1 252:1 0 384M 0 part /boot
|-vda2 252:2 0 127M 0 part /boot/efi
|-vda3 252:3 0 1M 0 part
`-vda4 252:4 0 249.5G 0 part
`-coreos-luks-root-nocrypt 253:0 0 249.5G 0 dm /sysroot
vdb 252:16 0 200G 0 disk
vdc 252:32 0 200G 0 disk
On Linux and other Unix-like systems your block devices are represented in the filesystem as files so each block device has its unique path, the same way as regular file.
Instead of running
lsblk
you can rundf
command which will show you those paths however it will show you only the devices which are already mounted.All block devices on your system start with
vd
so you can simply run:to list them all.
So if you want to mount e.g. your
vdb
andvdc
disks, the values forspec.storageClassDevices.devicePaths
will be/dev/vdb
and/dev/vdc
