Certain RAID controllers (PERC H730P) require physical disks
to be switched from non-RAID (JBOD) mode to RAID mode to be
included in a virtual disk. When this conversion happens,
the available free space on the physical disk is reduced due
to some space being allocated to RAID mode housekeeping.
If the user requests a virtual disk (a RAID 1 for example)
with a size close to the max size of the physical disks when
they are in JBOD mode, then creation of the virtual disk
following conversion of the physical disks from JBOD to RAID
mode will fail since there is not enough space due to the
space used by RAID mode housekeeping.
This patch works around this issue by recalculating the RAID
volume size after physical disk conversion has completed and
the free space on the converted drives is known. Note that
this may result in a virtual disk that is slightly smaller
than the requested size, but still the max size that the
drives can support.
