I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:

I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there.

Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!

View 2 Replies View RelatedHow do you find the device (e.g. /dev/*) for a mounted USB drive in Linux (Ubuntu 10.04)? I'm trying to format a Cruzer USB flash drive, and when I plug it in, the icon for the mounted filesystem appears on my desktop. However, when I open GParted, it doesn't list the filesystem as an option to partition.
The recommendations I've found through Google include monitoring tail -f /var/log/messages, which they claim should list the device name when the drive is mounted, but this never happens for me. I've also read that the USB drive would usually be linked to /dev/sdb, but this appears as a broken link on my filesystem. How else would I find the device?
Found the below from RedHat Knowledgebase
The Completely Fair Queuing (cfq) scheduler in Red Hat Enterprise Linux 5appears to have worse I/O read performance than in version 4. It appears as though the Completely Fair Queuing I/O scheduler (cfq) has a regression and thus exhibits reduced read-side throughput which can affect performance for both local and NFS mounted file systems.
One way to mitigate this is to set the cfq's slice_idle parameter to zero. To change this value, execute the following command echo 0 > slice_idle in the /sys/block directory appropriate for your situation, as shown below:
echo 0 > /sys/block/hda/queue/iosched/slice_idle
We are using NFS file systems in RHEL 5.3. I would like to know how to find which /dev/Device is being used by the NFS file systems, so that I could try setting the slice_idle to '0' to see if there is any difference in performance? In /etc/fstab I only see the actual NAS volumes for the NFS file systems.

No problems, I let it search and it found the printer right away. When I ran XSane it could not find the device. I clicked help and it gave some steps. The first being to try as root. I opened a root terminal and entered xsane, it found and opened after a warning about running it as root. I checked and my user name and root are entered in the scan group.

I have this software I want to use to extract data from a Polar heart rate monitor. Everything related to sound is working flawlessly. I just need to know the device name of the front microphone ("microphone" 2" in sound properties) so that I can insert it in the following cli command for a script: "rs200_decode -m /dev/XXX -b -o /home/user/dumb.bin"
I checked the forums but I only see references to /dev/dsp, /dev/audio, etc. I don't have any of those but rather /dev/snd/controlC0, hwC0D2, pcmC0D0c, pcmC0D0p, pcmC0D1p and pcmC0D2c.
I'm using Ubuntu 10.10 32-bit. The sound card is a generic HDA Intel audio chip. Lspci outputs: Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller.
How do I find the device that a usb stick is tied to (eg. /dev/sdc)
