[Ocfs-users] problem with OCFS label

[Wu, Hai]

I used this command to create volume label on OCFS:
mkfs.ocfs -F -b 128 -L data13 -m /oradata/data13 -u oracle -g dba -p 0775 /dev/emcpowerp1

emcpowerp is composed of /dev/sdad and /dev/sdk. It seems the above command created the same labels for /dev/emcpowerp1, /dev/sdad1 and /dev/sdk1. 

But when I tried to mount this ocfs filesystem by label, it gave me the following error.
# mount -L data13 /oradata/data13
mount: the label data13 occurs on both /dev/emcpowerp1 and /dev/sdad1 - not mounted

Is this a bug? Or does it mean OCFS label would not work for EMC PowerPath devices?
Thanks,
Hai
