I'm thinking in use iSCSI, exported from the NetApp filer. I think
this will be the best solution with RHEL3, because I have the same
problem with the service data partition (I think that actual cluster
suite don't support service data over nfs).

The RHEL3 I have installed in this servers is Update 3. But I haved
read in someplace that to support iSCSI you need Update 4. Are you
sure that U3 support iSCSI? This will be great ;)

hmmm... This means that RHEL4 cluster suite will support all the
things I need? ;) (that it's: no shared disk between servers, and
aplication service data over nfs)
Wouu... ;) 

I think I will try tomorrow with iSCSI, and maybe reinstall all the
things in 1 month when rhel4 is avalaible (14-feb I think).

Thanks
