Ocfs2 users - May 2010 - tunefs.ocfs2 resize issue,

Hello

Sorry if ask a question already seen before but  i'm new to ocfs2 and 
was not able to find a proper answer on the web.
We re using ocfs2 on a two nodes system with SAN disks.
We need to extend 3 of our partitions so we added 3 LUN of 10g on each , 
then restart powerpath, then recreate the partition table using fdisk in 
order for it to see the newly added space.
All went ok and fdisk shows us the proper size for the devices.
But when it comes to resize the fs using tunefs.ocfs2 -S <device>
we encountered this error :
tunefs.ocfs2: I/O error on channel while initializing the cluster group 
starting at block n
we then ran the tool
fsck.ocfs2 -f /dev/emcpowerc1
which returned with all passes ok, but we are still not able to resize 
our fs.
NB: the fs were not mounted when we ran the tunefs.ocfs2 tool

Thanks for the help.

Stephane.
