Re: [Linux-cluster] want to use GFS2



Thanks All for your reply,
 
I treid it with lock_nolock and its working fine with me, But only in one server at a time
But I want to take a benafit of GFS2 to use this storage with two servers as a central storage.
So each one can write easily on it.
My point is this can we use it without making cluster UP?
 
or is there any other filesystem through which I can fullfill my requirment?

Just two cents, I believe Red Hat does support GFS2 on single server using lock_nolock, because we do SAN "snaps" of actively clustered GFS2 volumes (simple flatfiles, no databases) and present the snap luns to a media agent server to backup the data oob.  RHN was okay with that configuration and we have been running it this way on GFS and GFS2 for 5-years without issue.

Hi,

Well, technically you can use GFS2 without a cluster setup.
I believe Red Hat doesn't support it, and the storage can't be mounted by more than a single computer (with "lock_nolock"
locking protocol), but it can be done.
