[Ocfs-users] problems creating ocfs filesystem

[Sunil Mushran]

mkfs.ocfs, as well other ocfs userspace tools, use the raw interface
as a way to perform o_direct operations. They do so because of a
limitation in 2.4.9 (RHAS21).

What it is doing is, mapping /dev/sdf1 to /dev/raw/raw41.
It scans the /dev/raw/rawXX from 0 to 255 and uses the first
available.

Do,
raw /dev/raw/raw41 /dev/sdf1
See what the error is. Maybe that raw device is not in /dev/raw.
If not, mknod it.
