[SOLVED] error: /dev/sdb/: no medium found - Fresh Install

Greetings All,

I've got a fresh arch install with some error messages on boot. Never seen anything like this in over 20 arch installs. Scanned the webs but no substantial search results, nothing in the journal. Keeping in mind that the machine in question has only one hdd, these are the error messages:

error: /dev/sdb/: no medium found
error: /dev/sdc/: no medium found
error: /dev/sdd/: no medium found
error: /dev/sde/: no medium found

I don't know if this is a correlation, but in BIOS I can select to turn on up to 6 SATA drives. Other than that, everything works absolutely fine. I guess one option is to disable loglevel messages, but I'd really like to know what's going on. Anywho, I could really use some help on this one. If you guys have any questions feel free to ask, and sorry that I can't provide more information.

Okay, seems like whenever you make a post, two minutes later you find an answer. Turns out this machine has a card reader, four to be exact, so problem solved.

Start with fstab and then check any automounting setup you're using.

fstab just has /dev/sda1 and /dev/sda2, other than that there's no automounting that I'm aware of. Any ideas how grub is able to detect those drives?

Are you sure it's not boot order or something similar in BIOS?

Just checked, 1 is USB/DVD 2 is HDD, so it's not the boot sequence.

you can access to fdisk -l ??

Well, I suppose that this is somekind of signature, no?

Disk /dev/sda: 232.9 GiB, 250000000000 bytes, 488281250 sectors

/dev/sda3  41947136 488281216 446334081 212.8G Linux filesystem

Should have thought of this before, but I unplugged the card reader, a Dell TEAC CA-200 USB Flash Card Reader, and the error messages go away. I also found this thread:

You can prevent lvm2 from scanning the card reader by using the global filter.  Instead of using drive letters for the filter, like  'sde' which is liable to change,  use the id of the device(s).

E.g.:
# ls -l /dev/disk/by-id/ | grep sd[e-h]

lrwxrwxrwx 1 root root    9 Apr 13 11:06 usb-Generic_USB_CF_Reader_058F312D81B-0:1 -> ../../sdf
lrwxrwxrwx 1 root root    9 Apr 13 11:06 usb-Generic_USB_MS_Reader_058F312D81B-0:3 -> ../../sdh
lrwxrwxrwx 1 root root    9 Apr 13 11:06 usb-Generic_USB_SD_Reader_058F312D81B-0:0 -> ../../sde
lrwxrwxrwx 1 root root    9 Apr 13 11:06 usb-Generic_USB_SM_Reader_058F312D81B-0:2 -> ../../sdg

Since all card reader slot device ids contain the unique 'Reader_058F312D81B',  you can use the following global filter in lvm.conf.

"r|/dev/disk/by-id/.*Reader_058F312D81B.*"     # filter out card reader slots

Good luck!

I really doubt they're looking for more help nearly 6 years later.
