Are you using OCFS2 to store Oracle database files? What database
version do you use?<br>
<br>
Thanks,<br>
Herbert.<br>

<div>thanks for quick response, so does this
mean, we can even remove that option on
current 1.4 OCFS2 and prepare new host also
without this option and we swing the storage
and we should be fine?

The datavolume option didn't really
do much. It just changed the
filesystem identifier from OCFS2 to
OCFS V1, so some programs which
shall not be named would detect it
as OCFS and do something special.
Those programs have long since been
fixed. And there's absolutely no
other functional behavior change
with or without the parameter.<br>
<br>
Thanks,<br>
Herbert.

1.6 could

after moving
