Quad Disk Layout

By default the LSQuad comes with 4 disks with each partition as part of a raid array.

$ fdisk -l /dev/sda

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         125     1004031   83  Linux
/dev/sda2             126         748     5004247+  83  Linux
/dev/sda4             749      121601   970751722+   5  Extended
/dev/sda5             749         873     1004031   82  Linux swap / Solaris
/dev/sda6             874      121478   968759631   83  Linux

Note that the above table is for a 1TB disk. All disks use the same size for all partitions other than /dev/sda6, which simply fills any remaining space.

Raid Levels


Boot drive. It is mirrored across all drives. The stock firmware will automatically synchronise all sXa1 partitions across all disks when it starts. Note that UBoot is not raid-aware - it simply boots from sda1, which is the first drive on the first disk (i.e. highest in the physical machine).


Root partition, /. Mirrored, just like sda1. Again stock firmware will automatically synchronise with other partitions upon boot.


This is simply an extended partition to hold other logical partitions.


Swap partition, and is striped across all the drives.


Data Partition. By default is RAID 5 (striped-with-parity) across all drives. Web interface lets you switch between RAID levels or simply turn it off for these drives.
