Cannot open master raw device '/dev/rawctl' (No such file or directory)
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.
Newbie. So no shortforms pls.
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.
