3-Administering the MaxNAS R8
4.2.2 Expanding NAS volumes
To expand the network accessible space of a RAIDset to take over unused space, select the
desired RAIDSet and click | on the RAID information screen (see above, section 4.2.) |
The RAID Configuration | page will |
appear. Select the “Expand” tab in the tab bar (see illustration.) The Expand RAID Space screen will appear. Select the new percentage of the resulting volume to be used for network access. Remaining space may be allocated for
iSCSI targets. Click Apply to complete the operation.
4.2.3 Migrating RAIDSet
The MaxNAS R8 allows RAIDsets to migrate on to unused disk modules as well as change the RAID level to fully utilize resources or to afford user flexibility. Online RAID level/stripe size migration can prove helpful during performance tuning activities as well as at the addition of physical disks to the MaxNAS R8. For example, in a system using two drives in RAID level 1, you could add capacity and retain fault tolerance by adding one drive. With the addition of third disk, you have the option of adding this disk to your existing RAID logical drive by migrating from RAID level 1 to 5. The result would be parity fault tolerance and double the available capacity without taking the system offline. To migrate a RAID 0, RAID 1, or RAID 5 volume,
Select the desired RAIDSet and click 
on the RAID information screen (see above, section 4.2.) The RAID Configuration page will appear. Select the “Migrate RAID” tab. A list of possible RAID migration configurations will be listed. Check
the “available disk” checkboxes corresponding to the disk(s) you wish to add, Select the desired migration scheme and click Apply . Not all migration options will be available depending on the current RAID configuration.
