sda turns to sdb or sdc after install PVE over Debian 12.

[Gilberto Ferreira]

Hi everybody

Don't if someone can help out.
I was able to install Debian 12 over a Dell R650xs using 3 NVME.
Strangly enought, the NVMe's appears to me as sda, sdb and sdc.
During the Debian installation, everything goes good.
After install Proxmox over Debian 12 and reboot, sda turns into sdb or sdc.
I have another Dell R650xs that works fine and after install PVE sda remains as sda!

Anybody knows how can I prevent this to happens?

Thanks

This is normal, depending on speed of disk initialization they may have change order, once second disk will be faster, then third or first. That's why in fstab you should use UUID or path (/dev/disk/by-path)

In fact, I am using UUID in /etc/fstab.
The Debian installer to that normaly.
I don't get it why the other same server with the same set of NVMe don't happen the same issue.

This is not an issue, this is normal behaviour. This may depends of many factors , e.g.: bios version, motherboard, bpn firmware version, disks (and it's firmware), hba/raid controller (and it firmware version), bios settings (e.g. disk spin up parameter), cable length or even a simply luck that "first" disk initialized as first.
