Vladimir,

we use OCFS2 right now. But it is highly discouraged by Oracle, to use
OCFS2 and ASM in parallel. And on the RAC, there are about 20 non-SAP
databases running on ASM, so...

Besides, every now and then we have problems with OCFS2 (some of them on
the ocfs2 mailing list ;-)), so our db team wants to switch to ASM. And
since SAP allows ASM, I'm out of arguments.

I'd prefer SAP db anyway ;-)

Regards,
Werner
