Can 2 File Systems sit on the same MetaVolume ?
I have a NS700G which takes storage from a DMX with 17 GB HVs.
I have a user that wants 2 x 10 GB NFS "exports" from the Celerra NAS.
So, I want to create a "striped metavolume" that consists of 2 x 17 GB disks (34 GB).
Can I put the 1st file system on the "top" of the "Striped Metavolume", and then put the 2nd file system on the bottom half of the SAME "striped metavolume"?:
# nas_fs -name firstFS create size=10G mtv1
# nas_fs -name secondFS create size=10G mtv1
i.e. - can 2 x FileSystems sit on 1 x MetaVolume?

Hi,
yes, you can. If you want to use MVM ( Manual Volume Management ), create two slices of 5GB on each dvol, then stripe them togehter, then create a metavolume, then the filesystem. You will be able to use the free space to create the second filesystem.
Another option is to use the AVM ( Automated Volume Management ), and enable the default_slice_flag on the system pool ( possibly symm_std ). It will automatically slice the disks before create the filesystems, so you will use all the capacity of the disks.

These are two different ways to create two filesystems on the metavolume:
- create two slices out of the metavolume and create therein the filesystems
or
- create a storage-pool (with nas_pool) with the metavolume and create your
filesystems within that pool.
The second one is the way I'm working on my boxes.

A Celerra Metavolume is only used by one FS.
If you want to create two FS you have to create/use two Celerra Metavolumes.
