[Ocfs2-users] Get error on mount.ocfs2 "No such file or directory while mounting ...."

[Zosen Wang]

I try to install 2 nodes RAC in Linux 2.6.9.-22.EL by using Jeffery Hunter’s paper. I am getting problem to mount the ocfs2 file system. The following is mount command error output:
  [root at b30-rh1 ~]# mount -t ocfs2 /dev/sda2 /u02
  mount.ocfs2: No such file or directory while mounting /dev/sda2 on /u02. Check 'dmesg' for more information on this error.
   
  I can not get any error msg from dmesg or syslog. 
   
  Please help and thanks in advance.
