Shared Mounted Logical Volume

NTMG — Fri, 20 Sep 2002 08:17:57 GMT

Hi,

I have an OPS cluster with RAC and 3 shared VGs.
I am using raw lvols apart from 2 which are mounted.
If I create a file in the mounted lvols (which are shared) then I cannot see it on the other node straight away.
I have to unmount, fsck and mount to see it on the other node.
Is this the case with shared mounted lvols?

Thanks in advance

Yes, you cant mount/use shared lvols like this. If you want to share have it mounted on one server and use something like nfs to mount it on another unix server, or samba for a windows server.

You must not share filesystems between nodes. THis will lead to data corruption.

When using SGOPS, only raw logical volumes that are under control of RAC can be kept consistent (i.e. the raw lvols).
