Bug#509875: extended partition is too small when creating logical partition at end of volume
Package: partman-base
This issue was encountered using a lenny i386 CD, the CD was
downloaded/burnt around 2008-09-05
Consider the following volume:
total capacity: 80GB
Primary partitions: 128MB (/boot), 10GB (FAT32), 10GB (NTFS)
The user now chooses to create another 10GB partition, and when
prompted, chooses:
- type: logical (not primary)
- location: end (not beginning)
The partitioner creates a 10GB extended partition at the end of the
disk, and a 10GB logical partition within this space.
The other 50GB, between the end of the third primary partition (NTFS)
and the beginning of the logical partition is unusable.
I believe the correct behaviour would be something like this:
- warn the user in any situation where unusuable gaps will exist after
partition
and/or
- ask the size and location questions twice: once for the extended
partition, and again for the logical partition within the extended partition
and/or
- force the user to do things like this with cfdisk (bug 274290)
and/or
- automatically create an extended partition that uses all available
space (although this is assuming that the user won't replace or resize
the NTFS partition later)
Workaround:
- use gparted to resize the extended partition after installation of
Debian, leaving the logical partition in the same place
