158 SANRAD V-Switch User Manual
Expanding a Volume
If you are working in
a V-Switch cluster, a
volume must be
expanded on both V-
Switches.
You must expand a volume’s actual capacity, its capacity as identified by
the file server, to match its resized potential capacity using the CLI
command volume expand. If you do not expand the resized volume, its
resized capacity will not be available for storage use. After expanding a
volume, its host’s file server will show its new capacity but the disk
partition will not expand automatically. The host must expand the disk
partition.
In Figure 90, a concatenated volume is expanded from two terabytes to an
actual capacity of three terabytes to match its resized potential capacity of
three terabytes.
