IPBrick creates 2 mount points on the file system for storage (/home1, /home2). You can add further storage locations (IPBrick refers to them as work areas) using a provided script.
ipbrick:/opt/system/scripts# php system_add_new_workareas.php X
X refers to the number of extra work-areas you want defined.
Before running this script you must have already created the mount point, formatted the disc and placed the disc in /etc/fstab. You must refer to the multipath mapper device to mount the storage see blkid command
The script only places the work area under the management of IPBrick. This means you can add additional hard discs SAN LUNS, DRDB block devices etc, and then present them to IPBrick for management.
