Thanks very much for your prompt reply.
I went ahead and committed the changes using
Partition Magic, as described earler, and now
have the following:
Note: the /dev/hda2 at the very end of the disk
is the instant DVD play (Linux) partition
that came with the laptop's XP install.
[root at sonata /]# fdisk -l
omitting empty partition (5)
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 5201 41777001 7 HPFS/NTFS
/dev/hda2 9704 9729 208845 88 Linux plaintext
/dev/hda3 5202 5214 104422+ 83 Linux
/dev/hda4 5215 9703 36057892+ f W95 Ext'd (LBA)
/dev/hda5 8425 9703 10273536 8e Linux LVM
Partition table entries are not in disk order
[root at sonata /]# df -lH
Filesystem Size Used Avail Use% Mounted on
8.2G 5.7G 2.1G 74% /
/dev/hda3 104M 13M 86M 14% /boot
/dev/shm 526M 0 526M 0% /dev/shm
Both Linux and Windows boot up correctly, without any
I assume the next steps will be (from a rescue CD):
1) Use fdisk to format the unused 25 Gb space in the
extended partition, to a new type 8E partition.
2) Use pvcreate to create a new physical vol there.
3) Use vgextend to extend VolGroup00 to include the
new physical volume.
4) Use lvextend to extend LogVol00 by the XX Gb.
5) Do a file system check of LogVol00.
Does this look right? Am I missing any steps?
Thanks again for your help.
