I'm trying to migrate a few file systems used for cifs to a new larger storage pool. Is there an easy way to do this other than using robocopy and recreating the cifs shares? I was hoping there was a command within the celerra to migrate the file system across the storage pools without losing or recreating the cifs information.
- are you just using CIFS ? - do you have a Replicator license ? - is the CIFS server part of a VDM ? - how much downtime is acceptable ? - why do you move the file systems ? - what DART version ? - moving meaning copying onto another file system that is mounted on the same data mover ? - do you have a modem or ESRS dialin ?
We did this just 3 weeks ago to move from DMX storage to CLARiiON. We presented the new storage and used fs_copy to copy the file systems, unmount the old, name shuffle, remount the new with the same mount name and you are done. You will need to stop customer access during the fs_copy. We used replication for any non replicated volumes, so the cutover was fast. We kept the fs_copy short, by doing daily incremental copies till the cutover. If you have 5.6 you can replicate the replicated volumes as well due to 5.6 repl v2 supporting one to many replication.
Let me know if you need specifics on how we did this or more info.
system defined pools are a just a collection of LUNs that have the same performance criteria so you cant merge them.
Even if you could, just changing the pool wouldnt affect file systems that were already carved from that pool.
If you need to merge a file system then you have to use file-based tools
Replicator or fs_copy/nas_copy works on a block level for one *complete* file system - thats why its fast and convinient and copies all the security attributes of file/dirs So you cant use it to "merge" two or more file systems into one - its only one-to-one and src and dst have to be exactly the same size
for file-based tools your options are: - client side copy with emcopy/robocopy/rsync/SecureCopy/... - server_archive - NDMP backup and restore
Here's the background. When we first setup the NAS, we got some 500GB ATA drives, they had to be setup in a raid3 (this was a few years ago) I just got some more ATA drives but they are 1TB drives, which I was told should be configured in a raid6. My raid3 pool is about 98% used. So I want to migrate the file systems from that storage pool to the new larger raid6 storage pool. Then I will take the 500GB and recreate them as a raid6 group so they are in the same storage pool. I'm running 5.5.35-0 code.
