Device file paths change between reboots

[durandguru]

Hi,

I have 4 nvme disks on my ubuntu 24.04 server. After every reboot the nvme disks have another identifier. So /dev/nvme1n1p1 can be /dev/nvme0n1p1 .

For the disk which hosts the / mount everything works fine. But the 3 data diks have every reboot another ID (apparently an known issue in ubuntu).

In Beszel the graphs are coupled to the name of the disk, so after a reboot the graphs kinda work after an time but history is wrong. My mounts are mapped by uuid.

Is there an soulution for this?

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv 914G 33G 843G 4% /
/dev/nvme1n1p1 916G 633G 237G 73% /mnt/media
/dev/nvme2n1p1 916G 108G 763G 13% /mnt/files
/dev/nvme3n1p1 1.8T 1.2T 605G 66% /mnt/photos
/dev/nvme0n1p2 2.0G 96M 1.7G 6% /boot
/dev/nvme0n1p1 1.1G 6.2M 1.1G 1% /boot/efi

Good point, I hadn't considered that.

We can use the UUID, but it would not be ideal to display something like e858d363-aaa8-4a5e-9da1-fbe0ef63af1b Usage as the chart title.

Maybe we can use the label as the identifier if it's defined?

lsblk -o NAME,LABEL,MOUNTPOINT

Labels won't stick for now on 2 drives. I will troubleshoot...

Or use the name for docker in the volume after extra-filesystems?
volumes:

• /mnt/disk1/.beszel:/extra-filesystems/sdb1:ro

NAME LABEL MOUNTPOINT
nvme3n1
└─nvme3n1p1 /mnt/photos
nvme2n1
└─nvme2n1p1 files /mnt/files
nvme1n1
└─nvme1n1p1 /mnt/media
nvme0n1
├─nvme0n1p1 /boot/efi
├─nvme0n1p2 /boot
└─nvme0n1p3
└─ubuntu--vg-ubuntu--lv /

Btw, with extra disks the title and explanation is displayed. I get why it is there but it kind off says the same :-)
