Disk Manager also allows the administrator to have transparent access to data backups in CD, DVD or USB media created with the Snare Central Data Backup utility directly, without needing to restore data to the local hard drive.

IMPORTANT: Please note that in order for Disk Manager to be able to access iSCSI disks (typically used in Snare central cloud based installations), it is necessary to first configure the internal Snare firewall to open the default TCP port 3260 |

IMPORTANT: The disk manager functions described in this section will only work with systems that have a base install of 400GB disk or larger as this created additional disk partitions that can be resized. If systems are installed using the minimum sizing as detailed in the installation guide then Disk Manager can not resize the disks as it would require unmounting the root file system which is not possible within the application. For sizing options, please refer to the Installation Guide for Snare Central > Minimum Requirements. |

Resizing a local file system

IMPORTANT. Before changing the sizes on any file system, unmount any NAS, DVD, CD or USB device from the server as it may interfere with the resizing process and lead to unpredictable results. DO NOT JUST INCREASE THE SIZE OF AN EXISTING DISK WHEN USING VIRTUAL BASED SYSTEMS, ADD A NEW DISK OF THE EXTRA SIZE CAPACITY YOU NEED TO THE SYSTEM. Due to the way the disks are managed and allocated there is no support for extending the size of a disk, it has to be a new disk for the Snare Disk Manager to manage the disk and slice up the space for partitions to use. If you want to use a new contiguous larger disk for storing the data then you will need to build a FULL new Snare Central and then do a side by side migration if you want to keep the existing data to use this newer larger disk space. Or you can rebuild the existing system if you are ok to wipe all the data in the existing system. |
Each of the local file systems on the server is represented by a cylinder in the Disk Manager user interface. Another cylinder represents the amount of “Free Space” available on the server.
