Adding and Moving a
Data Stripe Group 2New 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.
1Label disks for the new stripe groups you want to add to the file
system.
2If 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 Checking
the File System.
4Add 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.)
5Stop the File System Manager (FSM) for the desired file system.
6Run cvupdatefs.
7Restart 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.
