Hi,  #1 Is it as easy as hitting the failover Button? Yes. Simply create a loopback replication between your original fs and the new one, then switchover the replication session.  #2 Will I have to recreate all user shares? No. You can unmount the original fs from it's mountpoint, then mount the new one on the original mountpoint. Example : # server_umount VDM -p fs01 # server_mount VDM fs01_new /fs01  You will notice a 1-2 minutes downtime, or even less. Since the shares are based on the mountpoint, and not the file system name, you don't need to recreate your shares.  #3 Will it automatically use the interface assigned to the CIFS server that is mounted under the VDM? Yes. You don't need to worry about it.   Obs.: if you want the best file system layout in your case would be to use 4 X R5 4+1, then stripe your FS across these 20 spindles. This is what AVM tries to do when there are available disks. This also will give you a future grow room.  Gustavo Barreto.
High Overview:  I have a file system for user Home Directories.  Apparently, there has been some "slowness" during Logoffs.  Roaming profiles are used with our users.  I just migrated from Physical Servers to the Celerra.  I didn't think it was Celerra related until I opened Celerra Monitor and noticed that starting at 4:00 p.m.  - 6:00 p.m. The File System is "Hit" with about 1200 - 2000 IOPS.  Which makes sense since the user community (800 Users) are logging off and Roaming Profiles are synchronizing.  I noticed the File System was created from 3 volumes within 2 Raid Groups (Raid 5 4+1).  The Raid Groups are composed of 600 GB 10K Luns.  Hence, both Raid Groups combined will offer about 1200 IOPS.  I want to perform the following:  I will create a Storage Pool composed of (3) Raid 5 (4+1) Groups.  The hard drives are going to be 300GB 15K FC Drives (180*15 = 2700 IOPS).  The Current File System is mounted under a VDM.  I will replicate to a new File System composed from the NEW Storage Pool (Which will be dedicated to HOME directories ONLY).  Mount it under the same VDM.  Once Synchronized:  #1 Is it as easy as hitting the failover Button? #2 Will I have to recreate all user shares? #3 Will it automatically use the interface assigned to the CIFS server that is mounted under the VDM?  I will test but just wanted to get some general feedback.  Thanks Everyone,  Damian
What is the proper Celerra Replicator Failover?
