If you are performating a manual partion in 9.0-RC2 bsdinstall and
you delete any created partition except the most recently created
one, the total remaining space will be miscalculated. Reproducable
as shown below.
Workaround: if you delete a partition that is not the last
partition that was created, delete all partitions created after that
partition before continuing. Order does not seem to be important.
The results are similar with other hard drive sizes, with the i386
or amd64 distributions, and with either 9.0-RC2 or 9.0-RC1 (I did
not go back and check install discs prior to RC1)
Reproducing the miscount:
A 114 GB drive is used for this example:
Select Manual Partitioning
Perform the first Create on the drive and select GPT
Creating the first partition: "Add Partition" "size" shows 114GB
Change size to 4GB, set mountpoint to / and tab to OK
(agree to the boot partition creation)
Create a second partition: "Add Partition" "size" shows 110GB
Adjust size to 10GB, set mountpoint to /usr and tab to OK
Create a third partition: "Add Partition" "size" shows 100GB
Adjust size to 20GB, set mountpoint to /var, and tab to OK
Create a 4th partition: "size" shows 80GB remaining
Adjust size to 40GB, set mountpoint to /data, and tab to OK.
There is 40 GB remaining on the drive. Now change the
size of /var. First, delete the currently configured /var
partition.
In the Partition Editor, adding up all the lines on the screen shows
54GB (plus a 64K boot) as allocated, so there should now be 60GB
remaining. But the deleted /var space has not been added back into
the total.
Select Create again: "Add Partition" "size" shows 40GB
Adjust size to 30GB, set mountpoint as /var, tab to OK
A subsequent "Create" will show that 20GB is remaining, rather than
the actual remaining 30GB. Selecting any size 20GB or larger for
/home will give you a 20GB partition, and then an additional create
will show the 10GB.
