Bug 149707 – udev-100-r2 does not create /dev/hda

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Xake 2006-10-01 03:59:45 UTC]

I have had two SATA discs and a PATA DVD+/-RW in my computer for about a year now, and only have had the /dev sd# and /dev/hdc devices to care about. Since last week I have the need to try and collect info from a PATA-HDD I know only has one partition with the ext3 fs.
The problem: /dev/hda never got created. dmesg finds the HDD, identifies it and tells me that hda exist, but udev seems to never create its node or any nodes for its partition.

could you please include the output of /proc/partitions, as well as your dmesg boot log (please attach it here).

/proc/partitions

[Comment 4 Robin Johnson 2006-10-03 14:41:40 UTC]

This is not a udev problem.
Something else is wrong with your system.
hda doesn't appear in /proc/partitions. 

maybe dig in /sys/bus/ide/devices or /sys/block/hdX and try to figure out why.

if you make the devices nodes manually with mknod, you'll probably find that the kernel will give you errors when you try to access them.

[Comment 5 Xake 2006-10-03 15:55:53 UTC]

I can find the disk in /sys/bus/ide/devices/0.0/ but not in /sys/block/
Trying to make the node by hand I have not since I'm not sure in how to use mknode.

[Comment 6 Robin Johnson 2006-10-03 16:23:19 UTC]

this will make all of the device nodes for you:

mknod /dev/hda b 3 0
for i in `seq 1 15`; do
mknod /dev/hda$i b 3 $i
done

see /usr/src/linux/Documentation/devices.txt for other numbers.

but something is definetly wrong with your hardware or kernel, this is not a udev issue.

maybe check if support for IDE disks is compiled into your kernel?

[Comment 7 Greg Kroah-Hartman (RETIRED) 2006-10-03 21:54:26 UTC]

Even creating those device nodes by hand will not fix the issue here.

This is a kernel configuration issue, not a udev one.  closing...
