YAST Bootloader configuration picking up strange device

I don’t see anything about msdos with gdisk, either.

GPT fdisk (gdisk) version 0.8.10

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present


***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format

Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.

Hi, welcome back.:wink:

I am going to read through this thread, then look over your output. I will be back as soon as I can.

23

Hi,

If that Dos partition is around 7 mb
it is created by using grub2. I saw this in a fresh install of
openSUSE 13.2 on a clean (virgin) disk.:
It wouldn’t allow me to delete. This happened in a none
UEFI system.

I’m not sure enough if this really a Dos partition, I will try to take a look at
it tomorrow.

24

These indicate an msdos partition table

25

Maybe try

df
26

Other than throwing up an error, does the system boot and run okay?

27

Now, this is strange.

Under devices, you should only have ONE pair of listings for sda, either the red-highlighted or the blue-highlighted, but not both:

28

It does. I want to solve this for my own understanding of the inner workings of my system, rather than any problems this issue is causing.

29

… which is exactly what I would want if it was my machine, so we are thinking much the same, here.

30

Well, udev is responsible for generating those persistent names, so could be a quirk of how /lib/udev/rules.d/60-persistent-storage.rules is triggered with this particular hardware?

Might be interesting to execute the following to see what keys are enumerated

/lib/udev/scsi_id --export /dev/sda
31

Further to this, ‘udevadm test <device path>’ can be used to simulate a udev event and print debug output. (It will show what rules matched for example.)
For example

udevadm test /sys/class/block/sda
32

This command output nothing for my system.

udevadm output:
