[Ocfs-users] OCFS write/read across 2 nodes

[Dermot Reynolds]

Hi,

If I have ocfs on 2 nodes should I be able to do the following:

t=0
    Node A
        echo "1" > /ocfsmount/a

    Node B
        cat /ocfsmount/a

>>>>Question 1: At this point should I see "1"?

t=1
    Node A
        echo "2" > /ocfsmount/a

    Node B
        cat /ocfsmount/a

>>>>Question 2: At this point should I see "2"?

The problem is that at t=1 I am still seeing "1", however when I run
ocfstool on node B I can see "2".

Assuming that this is correct behaviour this must imply that Oracle writes
and reads to/from the filesystem in a different manner.
Is this where o_direct comes in?

Thanks
Dermot
