62 Section 3 Menu Functions
3.6.6 Function “Units Assigned ” Figure 3.23
This is a list of the units [Raid LUNS] assigned to current volume group.
3.6.7 Function “Share Volume/Logical Manager” Figure 3.23
With this function you can create a Logical Volume ( lv ) inside a Volume Group.
The Logical Volume is the equivalent of partitions, which is the storage space available for
network shares. You can increase the capacity of an existing Logical Volume.
Depending on the needed capacity, the administrator can add more capacity to a particular
Logical Volume. Using Share Volume/Logical Manager function you can add disk space to a
new lv, or increase size on existing lv’s (you can’t decrease lv size). To set needed lv size use
scrollbar, next to which, on the right side is shown size available to use.
This function can be also be used to reserve disk space for “snapshots” and “swap”.
Usually for “snapshots” you need about 10% of new Volume Group.
The SWAP is additional disk space used by the system as system RAM cache..
3.6.8 Function “Snapshot definition” Figure 3.24
This feature takes so-called snapshots of the file system. The Snapshot function of Rorke
GalaxyLX NAS enables the system administrator to freeze the data content of the network
drive unnoticed from the users at a certain time. From this moment on, the users work on a
virtual data volume, all changes to the volume are stored in a different partition. The storage
of all changes is independent of the file-system Rorke GalaxyLX NAS uses on block-level.
