View Full Version : Cannot open master raw device '/dev/rawctl' (No such device or address)

It seems that I simply can't do anything with raw devices on FC3 Test1:

[root@SRV root]# raw -a
Cannot open master raw device '/dev/rawctl' (No such device or address)

Adding alias char-major-162 raw to /etc/modprobe.conf didn't change anything:
[root@SRV root]# modprobe raw
FATAL: Module raw not found.

The strange thing is that all the files are there:
[root@SRV raw]# which raw
/usr/bin/raw

[root@SRV raw]# ls -l /dev/raw
total 1024
crw-rw-rw- 1 root disk 162, 1 Jun 24 13:58 raw1
crw-rw---- 1 root disk 162, 10 Jun 24 13:58 raw10
crw-rw---- 1 root disk 162, 100 Jun 24 13:58 raw100
crw-rw---- 1 root disk 162, 101 Jun 24 13:58 raw101
crw-rw---- 1 root disk 162, 102 Jun 24 13:58 raw102
crw-rw---- 1 root disk 162, 103 Jun 24 13:58 raw103
crw-rw---- 1 root disk 162, 104 Jun 24 13:58 raw104
.............. (until 255)
lrwxrwxrwx 1 root root 11 Jul 24 12:25 rawctl -> /dev/rawctl

Is it something related to kernel and I need to recompile or is it some permissions issue or is it something else?

Well, it does not look llike a missing kernel module or something. Although I can't say that with confidence. I have just rebuilt 2.6.7 kernel from source (from kernel.org - not Fedora) and I simply could not find any references to support for raw devices in kernel configuration. Anyone knows where to find it in 2.6.7?

Or am I barking at the wrong tree?
