Using the Dynamic Resource Allocation Feature
StorNext User’s Guide 374
8 Run snfsdefrag -G <n> -m 0 -r /filesystemroot
where <n> is the zero-based number of the source stripe group from
which the move starts, and filesystemroot is the file name of the file
system tree’s root. You can specify multiple -G options to use
multiple source stripe groups.
9 Verify that no data remains on the original stripe groups.
10 Edit the file system configuration to mark the old stripe groups as
“Down.”
11 Stop the FSM.
12 Restart the FSM.
Moving a Metadata/
Journal Stripe Group 3
Metadata movement is performed on a LUN level, meaning you must
specify the source LUN and the destination LUN. The new sndiskmove
command that accomplishes metadata movement has two arguments: a
source and destination LUN.
After movement is complete, the physical source disk can be removed.
Note: The old stripe groups marked “Down/Readonly” must be
left in the file system configuration file.
Note: Although a stripe group can consist of multiple disks or LUNs,
the sndiskmove command moves only a single disk or LUN.
Consequently, references to “stripe group” in this section refer
to a single disk or LUN when migrating metadata with
sndiskmove.
