I have a system with multiple drives installed. I can see a list of all drives along with their UUIDs and labels using the blkid command (omitting some lines for conciseness):
root@ubuntu:~/avl# blkid
/dev/sdy1: UUID="F00D-78FA" TYPE="vfat" PARTLABEL="EFI system" PARTUUID="23fc9408-58b2-4905-983e-be0a4dc4adee"
/dev/sdy2: UUID="0c58da23-7ef5-4177-807c-d9164174c092" TYPE="ext4" PARTLABEL="Linux filesystem" PARTUUID="81c156e7-1113-46b4-9365-ed3a262fc475"
/dev/sdd1: UUID="ff1954fe-e8c1-4253-abbc-24d3d6c6a6c5" TYPE="ext4" PARTUUID="dae0a716-01"
/dev/sdb1: UUID="b26fadc6-cd26-4f2a-8a41-91238737ae4b" TYPE="ext4" PARTUUID="48b181eb-01"
/dev/sdu1: UUID="b9fb58ab-474c-4113-9789-c3a02ed49ddf" TYPE="ext4" PARTUUID="51d5e885-01"
/dev/sda1: UUID="08e865f9-0b47-407d-b103-b93836479de4" TYPE="ext4" PARTUUID="9bc2dad1-01"
You can see that my boot drive is assigned to /dev/sdy
. However, I'd like for this drive to be assigned to /dev/sda
instead.
My question is: Is there any way to force Linux to assign a drive with a given UUID to a given device filename?
3XY problem? Why should
/dev/sda
be better than/dev/sdy
? If you need to reliably identify a certain disk/partition/filesystem then use/dev/disk/by-id/
or/dev/disk/by-uuid/

/dev/disk
directory -- thank you for bringing this magical directory to my attention! After thinking through my question more, what I am looking for is indeed a way to reliably refer to a drive (as in a real, physical drive that is plugged into my chassis) – Paul M – 2018-04-11T19:12:51.917
