Use this procedure to make sure that an increase in capacity for a is recognized by a running the Linux Red Hat 6.2 or 7.1 operating system, using ReiserFS file systems.
If an increase in capacity for a standard logical drive is performed, the host does not immediately recognize the increase in logical drive capacity. Using the ReiserFS Resizer, the size of a file system might be increased (if free space is available on the ), and the increased capacity is successfully recognized by the Linux host.
start increaseVolCapacity logical drive=<"logical driveLabel"> incrementalCapacity=<capacity> disk drives=<(disk drive list)>;

df
resize_reiserfs -s + [size] [K|M|G] -f /dev/sdxx
In this command, -s + [size] [K|M|G] specifies the new ReiserFS file system size, in bytes, -f forces an increase in file system size without performing any checks, and /dev/sdxx is the storage subsystem being resized.
For example, an increase in the size of the storage subsystem "SDF1" of 500 MB is required. After locating the storage subsystem and ensuring that enough free space is available for an increase to occur, enter this command at the host prompt:
resize_reiserfs -s + 500M -f /dev/sdf1
