No medium found errors

Message

I receive this message at boot time:

journalctl -xb | grep medium
Error was encountered while opening journal files: Invalid argument
Mai 14 16:58:33 genkosta systemd-udevd[4352]: error: /dev/sdd: No medium found
Mai 14 16:58:33 genkosta systemd-udevd[4352]: error: /dev/sdb: No medium found
Mai 14 16:58:33 genkosta systemd-udevd[4352]: error: /dev/sde: No medium found
Mai 14 16:58:33 genkosta systemd-udevd[4352]: error: /dev/sdc: No medium found

I want to get rid of this annoying message.

Are these a multi-slot card reader with no cards plugged in?

JKosta · Post by **JKosta** » Fri May 15, 2015 4:51 pm

Maybe.
I don't know what media belongs to /dev/sdb, /dev/sdc and /dev/sdd.
My hard drive is located at /dev/sda.

JKosta,

dmesg will tell. Put your dmesg on a pastebin.

NeddySeagoon,

The dmesg's output is here:

Thats a four slot card reader. At least, its a four slot chip. If you are an a laptop, not all the slots may be fitted.

There are its 4 LUNs on the same device.

No medium found in not an error for a removable media device, its a normal operating state ... unless you know it has media inserted of course.

The error message is in error by classifying a normal operating state as an error.

NeddySeagoon,

My PC is a desktop.

There is no way to hide these messages in gentoo?

eccerr0r · Post by **eccerr0r** » Sat May 16, 2015 4:55 pm

I'd imagine these are benign. Probably have to hack the code to make it go away, but first: do you have any special rules in your udev.conf that perhaps accesses the drives?

On the other hand, I do not seem to receive these errors in systemd or openrc for my USB multislot readers - I don't have special configs for udev to view these disks.

JKosta,

Are you trying to auto mount these devices?
The errors are harmless.

JKosta · Post by **JKosta** » Sat May 16, 2015 5:49 pm

eccerr0r,

I have no special rules in my udev.conf:

Code: Select all

jribeiro@genkosta ~ $ cat /etc/udev/udev.conf 
# see udev.conf(5) for details

#udev_log="info"

I dont know if the message is benign but I do know that it's completely futile.

NeddySeagoon,

I'm not trying to auto mount these devices. I never use them.

I want a truly silent boot.
I want to use plymouth but its hard to make it.

Post by **NeddySeagoon** » Sat May 16, 2015 5:59 pm

JKosta,

There is a kernel command line parameter for a silent boot. You get nothing on the console after Unpacking the kernel ....
Try quiet
Its intended for a framebuffer console, so the messages do not disturb the graphic.

JKosta · Post by **JKosta** » Sat May 16, 2015 6:08 pm

NeddySeagoon,

I have this parameter set:

Code: Select all

jribeiro@genkosta ~ $ grep -v "#" /etc/default/grub 

GRUB_DISTRIBUTOR="Gentoo"
GRUB_TIMEOUT=10
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_VIDEO_BACKEND="vbe"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_GFXMODE="1920x1080x32"

The graphic is completely disturbed by the messages, it lasts about two seconds.

Post by **NeddySeagoon** » Sat May 16, 2015 6:19 pm

JKosta,

Something is probing those devices.
There are no errors in dmesg.

I suspect its a systemd set up thing but I don't use systemd, so I can't help further.
If it was the kernel there would be more in dmesg.

NeddySeagoon,

Thank you.

Post by **NeddySeagoon** » Sat May 16, 2015 7:51 pm

JKosta,

Long shot ...
Do you have those devices listed in /etc/fstab ?

JKosta · Post by **JKosta** » Sat May 16, 2015 7:54 pm

NeddySeagoon,

Negative:

Code: Select all

jribeiro@genkosta ~ $ grep -v "#" /etc/fstab
