Hi, I have a fairly new system running Ubuntu 24.04 with two sdd drives, both being 2tb in size.
Mvme0 is used for Ubuntu. Nvme1 I use basically for backups and very large media files. I auto mount
Nvme1 in fstab, with its unique uuid and all works fine as it should.

Since the initial install I kept noticing that these two SSD's filp flop the asigned devices. No errors, and
it seems like rolling the dice after a reboot, whether nvme1 becomes nvme0 and vice versa, as far as which
device it becomes assigned to. What little info i could find through searching, is that this is a timing issue during
boot. Even though the drives flip flop while being mounted, they are listed correctly in partitioning apps.

This so confuses me. It seems so odd, and I couldn't find a solution, or if this is even something I should
worry about?

System76
Thelio Mira desktop
Motherboard.... Z790 AORUS ELITE AX (rev. 1.0)
Intel(R) Core(TM) i9-14900K / 24 Cores with a ton of ram and Nvidia gpu.

I'm still catching up. My last system was so out dated using Hdd's without
uefi, before using uuid's became common in the fstab, and using the old grub as a bootloader.
I feel like a child trying to figure out linux all over again.

There is nothing to worry about, device names are not persistent and for this reason you should never use device name in fstab but UUID like you use now.

I was wondering the same however in my case I had device name set in fstab, took me a while to troubleshoot why my disk randomly doesn't mount.
