Re: Shared Volume between 2 non-clustered nodes
Trying to mount a VG on 2 servers at once is very dangerous and you have the potential for filesystem corruption if both are trying to run operations on the same file at the same time.

Re: Shared Volume between 2 non-clustered nodes
You might look at veritas (www.veritas.com); they have a distributed filesystem that might be of interest to you.

Re: Shared Volume between 2 non-clustered nodes
NFS or Samba on top of NFS is the only solution here.
Full SG as noted does not allow for simultaneous sharing.
Next.

Re: Shared Volume between 2 non-clustered nodes
I have a similar question,I have a pair of rp5470s which are hooked up to an EVA3000 (Veritas DFS not supported) and also hooked up via the same Brocade switch of the SAN to a Engenio Storagetek DS with SATA drives which we installed as cheap & fast backup solution. Now were adding an rp2470 to the SAN environment which is running our test instance. The plan is, in case of disaster , i run my test instance from the backup on the SATA drives. The trick is how to share the volume between the 2 servers, the direct solution that i deduced from the above comments is to create volume on the rp5470 node and export the volume to the rp2470 and make the volume on the rp2470 as RW until i do have an actual disaster.
What do u think??
thanks
vic

Re: Shared Volume between 2 non-clustered nodes
I would recommend you to go for the NFS or SAMBA mount and purge those files which ever needs to be cleaned. As Clay said, u can even allocated the same LUNs to both servers and import the VG in the second server with a map file taken from first server(with VGID). But going for this may create a possible filesystem corruption, we have tried it here. It worked for some time, but went into hung state after some time.
Hi victor, We would request you to rise another thread, since two questions by two different autoers will create lots of confusions. What you can do in ur case, is to give reference to this particular thread in ur thread if u find both of ur problems are simliar.

Sunil
