Thread: Cannot open master raw device '/dev/rawctl' (No such file or

  1. #1

    Unhappy Cannot open master raw device '/dev/rawctl' (No such file or

    I'm trying to create shared raw devices on opensuse 10.3. 1) I created raw partitions but when i try #raw -qa i receive the mentioned error. I tried all options but does not work.
    2) I would like to know how to check / access raw partitions from a different system within the network. may be some example commands to view raw partitions from system 2

    I created 5 logical partitions (under the extended partitions option on my second hard drive) of 150M each with fdisk /dev/sdb and i created the binding file as well. Any help is extremely appreciated.

    problem solved.

    make sure you have the following lines in /etc/raw file
    raw5:sdb5
    raw6:sdb6

    mkdir /dev/raw
    cd /dev/raw
    mknod raw5 c 162 5
    mknod raw6 c 162 6
    modprobe raw (this command creates the /dev/rawctl file)
    raw /dev/raw/raw5 /dev/sdb5
    raw /dev/raw/raw6 /dev/sdb6
    /etc/init.d.raw start
    chkconfig raw on

    SUSE Linux Lifetime - openSUSE

    You should upgrade, who knows what else has changed since 10.0 not only in kernel configuration but also in how to configure raw devices (not even mentioning that there were no more security updates for nearly 1.5 years now, although the kernel version clearly shows, that you didn't even care about updates at all).
