[Ocfs2-users] problem compiling ocfs2-tools v 1.4.1 on RedHat el5

[Sunil Mushran]

The mount option has precedence. As in, if you set it to datavolume,
the database will do odirect ios. As in, atleast odirect. It will do
odirect+async if that filesystemio_option is set to setall.

In your case, moving the script to a non-datavolume is easiest as you
could do it without having to remount the volume.

BTW, if you do remove the datavolume mount option, do remember
to set the filesystemio_options to atleast odirect (or directio) if not
setall. Do not leave it at async.

So which of these two has precedence over the other? Is it the mount option or init.ora parameter that decides what will be done?
