Virtual TapeServer 8.4 Configuration Guide

16 | Virtual TapeServer Configuration Guide
This file system requires approximately 1.25GB of free memory to run the gfs_fsck command.
Note that if the block size was 1K, running the gfs_fsck command would require four times the
memory, or 5GB.
l All data on a partition that is resized will be lost.
Keep in mind that performance and system operations will be slow when vaults are at maximum
capacity.
To add a vault to VTS
1. If necessary, connect the external storage device to VTS. Make sure that the cable is plugged
in and the link light is illuminated (for Fibre Channel) on the VTS server. The port to which the
external storage device is attached must be set to “physical”. See "Configuring Ports" on page
25 for more information.
2. Set up a partition on the external storage device (if necessary, ask your storage area network
administrator for assistance). The maximum size supported by VTS is 5TB.
3. Identify the disks.
a. Log in to the VTS server.
b. Become root:
su -
c. Enter the following command to determine the disk partitions:
fdisk -l
