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.
