* New status constant:
Disk.STATUS_FREE
LSM_DISK_STATUS_FREE
* In code document(Both in C and Python code):
New in version 1.2, indicate the whole disk is not holding any data or
acting as a dedicate spare disk.
This disk could be assigned as a dedicated spare disk or used for
creating pool.
If any spare disk(like those on NetApp ONTAP) does not require
any explicit action when assigning to pool, it should be treated as free
disk and marked as STATUS_FREE|STATUS_SPARE_DISK.
* Future design consideration for sliced RAID system(LVM RAID and EMC VMAX):
1. Introduce Disk.STATUS_FREE_PARTIAL
2. Introduce new class:
DiskSlice
properties:
id
owner_disk_id # Disk.id
block_size
block_count
start_block
status # FREE or SPARE or/and OK
