I have an ubuntu desktop system (VM guest), whose partitions were created by the install media. I wanted to expand the disk, so I shutdown the guest, and increased the disk size of the guest in the host. Now I need to expand the partitions in the guest - and here's the problem:
If I print the original table, this is what I get:
$ sudo fdisk -l /dev/sda
Disk /dev/sda: 37.6 GB, 37580963840 bytes
255 heads, 63 sectors/track, 4568 cylinders, total 73400320 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 499711 248832 83 Linux
/dev/sda2 501758 41940991 20719617 5 Extended
/dev/sda5 501760 41940991 20719616 8e Linux LVM
In the past, whenever I've needed to expand a partition, I would delete and recreate the partition with the same type, and the same start, but different end. It's not working this time:
Command (m for help): d
Partition number (1-5): 5
Command (m for help): n
Partition type:
p primary (1 primary, 1 extended, 2 free)
l logical (numbered from 5)
Select (default p): l
Adding logical partition 5
First sector (503806-41940991, default 503806): 501760
Value out of range.
Whaaat? How is it possible that I can't create a partition with the parameters that it had just a second ago? In any event, I quit. I thought maybe it was just an old fdisk, so I dug myself deeper into the hole:
I used parted to delete the partition, not knowing that it would apply the change instantly. (I expected it to require "write" or "apply" command when I was finished ... So I screwed up.) Now my original partition is deleted and I can't recreate it.
How can I force creation of a partition with value out of range?
