Re: How to mount a EVA Snapshot/MirrorClone on RHEL5.3
You would not be able to get this far with a bad copy of a vDISK.
Is it possible you created the snapshot before there was any data in the filesystem? Or you snapped the wrong vDISK.

Re: How to mount a EVA Snapshot/MirrorClone on RHEL5.3
I took the snapshot of the correct Vdisk after i mounted & copied some data on the FS.
Do i need to export VG from the Source host after i mount the FS ? and then import from the second host where i presented snapshots ?
Thanks

Re: How to mount a EVA Snapshot/MirrorClone on RHEL5.3
The only thing I can think of is that the data you wrote to the disk wasn't actually flushed to disk when you did the snapshot so I still showed the filesystem as empty.
I don't know if linux has a flush command to ensure all the stuff in memory is actually written to disk. If so you might want to do that before creating the snapshot. if not try to unmount the filesystem before creating the snapshot.
Once you create the new snapshot you can re do the pvscan, vgimport, etc.
If you want to do this everyday, a mirror might be a better method than a snapshot. You can then simply fracture and resync the mirror.

Re: How to mount a EVA Snapshot/MirrorClone on RHEL5.3
we dont need to import VG or anything
once we do vgs or vgscan, we see the VG , need to just mount it . It doesnt shows as Exported VG on the target host.
Thanks everyone for the help.
