The Disk Manager user interface shows the existing file systems represented as cylinders and their current usage (in above example, the root file system is showed in black and currently is a 53% of its capacity).
The menu includes:
Show/Hide (eye icon). Show or hide the non editable file systems.
Reset (circular arrow icon). To reset the disks to their original sizes.
Submit (right pointing arrow).
To submit disk resize changes.
NAS (cloud icon). To mount or unmount a NAS
system.
DVD (CD icon). To mount or unmount a CD, DVD or USB data backup.
Selecting a cylinder displays the filesystem status. The following image show the disk summary available by clicking on the corresponding disk or hovering the mouse on top of it.

When resizing any file system all Snare back processes need to be stopped and depending on the size of the file system this could take several minutes. |
Adding a new hard disk to Snare archive
If no more disk space is available, the administrator can add another physical disk (or disks) to the server and after a system reboot the new drive will be available as free space in the Disk Manager ready to be assigned to existing files systems as described.
In the case of upgraded servers, Disk Manager will detect the new disk and ask you if you want to use the whole disk to increase Snare capacity. Click the submit (arrow) button and after a few seconds the disk will be ready for use.

Snare Disk Manager requires that the new disk does not contain any partition nor any filesystem to be correctly detected and used. In any other case the disk will be ignored. |
All new incoming data will be stored in the new disk and all previously existing data will remain in your old disk as read only.
It’s is possible to add as many disks in the future as the underlying hardware allows to but only the last disk will be writable while the others remain read only. So the advice is to add a new disk only when the last disk is reaching 80% of its capacity so its performance remains normal.
