[Leap 15.1, xfce, kernel 5.2.11-1.g6385110-default] I have a machine with 2 nvme drives, 1 in the built-in motherboard m.2 slot (grub2 boots 15.1,"SX8200NP"), other in an m.2 slot on a pci-e expansion card (boots 15.0,"SX7000NP"). The dev names of the 2 nvmes seem to keep changing within the same boot. Here's an example from the logs with the mb nvme first called nvme0 by the kernel, then nvme1 by btrfs, then nvme0 by both smart and btrfs. But the device according to yast is still nvme1. Confusing, to say the least. I need someone smarter than me (which is just about anyone) to tell me what is going on here. What have I done :( Devices according to yast2 (partitioner): Device: /dev/nvme1n1 Device Path: pci-0000:02:00.0-nvme-1 Device ID 1: nvme-ADATA_SX8200NP_2I4520013773 Device: /dev/nvme0n1 Device Path: pci-0000:05:00.0-nvme-1 Device ID 1: nvme-ADATA_SX7000NP_2H4220054168 according to the journal, in chronological order: kernel: nvme nvme0: pci function 0000:02:00.0 kernel: nvme nvme1: pci function 0000:05:00.0 BTRFS: device label openSUSE-15 devid 1 transid 778057 /dev/nvme0n1p3 BTRFS: device label openSUSE-15.1 devid 1 transid 37777 /dev/nvme1n1p4 (note: if not apparent, this below is / on SX8200NP) kernel: BTRFS info (device nvme1n1p4): disk space caching is enabled kernel: BTRFS info (device nvme1n1p4): has skinny extents kernel: BTRFS info (device nvme1n1p4): enabling ssd optimizations kernel: BTRFS info (device nvme1n1p4): disk space caching is enabled smartd[1494]: Device: /dev/nvme0, opened smartd[1494]: Device: /dev/nvme0, ADATA SX8200NP, S/N:2I4520013773, FW:SVN139B smartd[1494]: Device: /dev/nvme1, opened smartd[1494]: Device: /dev/nvme1, ADATA SX7000NP, S/N:2H4220054168, FW:CB1.1.1 (note: if not apparent, this below is / on SX7000NP and the journal entry appears to be triggered by snapper. Why is snapper looking at something other than the running system?
