Use the following procedure to ensure that an increase in logical drive capacity for a standard logical drive is recognized by a host running Linux Redhat 6.2 or 7.1, using ReiserFS filesystems.
If an increase in capacity for a standard logical drive is performed, the host will not immediately recognize the increase in logical drive capacity. Using the ReiserFS Resizer, the size of a filesystem may be increased (if free space is available on the device) and the increased capacity is successfully recognized by the Linux host.
Important: In this version of the storage management software, increasing a logical drives capacity has only been verified with ext2 and ReiserFS filesystems.
1 |
Start the storage management software. Result: The Enterprise Management Window is displayed. |
2 |
Launch an Subsystem Management Window using one of the following methods:
Result: The Subsystem Management Window is opened in a separate window. |
3 |
Within the Logical View of the Subsystem Management Window, select a standard logical drive and increase its capacity using one of the following methods:
|
4 |
Launch a terminal window and at the host prompt, type the following, then press Enter: df Result: A list of all the mounted partitions recognized by the host is displayed. Information about the mounted partitions, including the available space, used space, and the directory to which the device is mounted is also displayed. |
5 |
Locate the device being resized in the list, and ensure that enough free space exists for an increase in capacity. |
6 |
Specify the new ReiserFS filesystem size. At the host prompt, type the following, then press Enter: resize_resierfs -s + [size] [K|M|G] -f /dev/sdxx where -s + [size] [K|M|G] specifies the new ReiserFS filesystem size, in bytes. where -f forces an increase in filesystem size without performing any checks. where /dev/sdxx is the device being resized. Example: An increase in the size of the device "SDF1" of 500MB is required. After locating the device and ensuring that enough free space is available for an increase to occur, the following command is entered at the host prompt: resize_resierfs -s + 500M -f /dev/sdf1 |
7 |
Locate the device and ensure that the increase in capacity was successful. At the host prompt, type the following, then press Enter: df <mount-point> |
8 |
Exit all applications and reboot the host operating system. |
9 |
Launch a terminal window and at the host prompt, type the following, then press Enter: df Result: A list of all the mounted partitions recognized by the host is displayed. Ensure that the filesystem was successfully resized. |
