There are several enhancements in ReadyNAS OS 6.7 relating to Flex-RAID volume management.
Factory Default on ReadyNAS with larger than 12 bays
From a factory defaulted state, ReadyNAS creates a volume based on the following table.
Note: ReadyNAS chassis with 6 bays and 6 populated disks will factory default with RAID 5. Any ReadyNAS with more than 6 bays that factory defaults with 6 bays will be a RAID 6.
If you destroy and re-create the default volume, the updated volume management appears during the creation stage. The volume manager will allow you to customize your volume for performance, reliability, and capacity.
You'll need to select the RAID level. If this is an expanded array, you will need to specify the more finite details, such as how many stripes and how many global spares.
RAID Group (stripe)
RAID Group expansion, or striping, allows you to add more RAIDs to an existing volume. This can be configured at volume creation or later on.
When adding a new RAID group, the drives need to match the existing amount of drives in a RAID group.
Expansion for RAID0 stripe and concatenated will be an option in an expansion wizard.
We allow converting between both concatenated and RAID 0 Stripe.
