[Ocfs-users] problems creating ocfs filesystem

[Sunil Mushran]

One solution would be to...
rm /dev/raw
mkdir /dev/raw
mknod --mode=+660 /dev/raw/raw1 c 162 1

I mean, you could clean out all the /dev/rawXX and create the
same an /dev/raw/rawXX.... raw1 to raw255.

Maybe better if,
raw -qa
shows no active raw mappings before you attempt this.
