Adding and Moving a 
Data Stripe Group
2
New functionality has been added to the snfsdefrag utility to support 
operations on multiple stripe groups.
Use the following procedure to add new stripe groups, and then move 
data off of the old stripe group.
1
Label disks for the new stripe groups you want to add to the file 
system.
2
If your StorNext configuration includes a failover environment, you 
must first shut down any standby FSMs that would start when you 
shut down the primary FSM. The move procedure will not complete 
successfully unless all FSMs are shut down.
3
(Optional) Run the cvfsck command on the file system. See 
.
4
Add the new stripe groups to the file system configuration and mark 
the old stripe groups as read-only. (Make sure the old stripe group is 
write disabled.)
5
Stop the File System Manager (FSM) for the desired file system.
6
Run cvupdatefs. 
7
Restart the FSM.
Note:
During Stripe Group Movement, affinities are preserved when 
files are moved from one stripe group to another. When you 
create a new stripe group to use with the Stripe Group 
Movement feature, the new stripe group must include 
sufficient space for its affinities. (You must add any affinities 
from the source stripe group to the new stripe group.)
Caution:
If you do not shut down standby FSMs, file 
system corruption or data loss could occur.
