Information and Recommendations: Repartition

[Mike McCarty]

I have a slightly confusing (to me) situation.

# mount

[snip]

/dev/sda1 on /mnt/usb type ext3 (rw,nosuid,nodev,user=jmccarty)

# grep sda1 /etc/fstab
/dev/sda1 /mnt/usb auto    noauto,user,exec 0 0

# fdisk -l /dev/sda1
 

Disk /dev/sda1: 82.3 GB, 82335020544 bytes
255 heads, 63 sectors/track, 10009 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
 

Disk /dev/sda1 doesn't contain a valid partition table


Question 1: If there is no valid partition table, then how did I do
a mount?

Now, concerning repartitioning. I installed FC2 last October on
a Compaq Presario. It is now a dual-boot system with Windows XP
bootloader managing a secondary boot to GRUB which manages
the Linux boot. Placing GRUB into the MBR is not an option on
this machine, as it causes F10 auto-recovery to begin.

I used resizentfs and parted when I did the install, intending
to make XP and Linux have about 20G apiece on this 40G drive.
But I flubbed something, and Linux now has only 7G. It looks
like this:

# fdisk -l /dev/hda
 

Disk /dev/hda: 40.0 GB, 40020664320 bytes
16 heads, 63 sectors/track, 77545 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
 

    Device Boot      Start         End      Blocks   Id  System
/dev/hda1               1        8625     4346968+   b  W95 FAT32
Partition 1 does not end on cylinder boundary.
/dev/hda2   *        8626       60915    26354160    7  HPFS/NTFS
Partition 2 does not end on cylinder boundary.
/dev/hda3           60916       61118      102312   83  Linux
Partition 3 does not end on cylinder boundary.
/dev/hda4           61119       77545     8279208    f  W95 Ext'd (LBA)
Partition 4 does not end on cylinder boundary.
/dev/hda5           61119       76505     7755016+  83  Linux
/dev/hda6           76506       77545      524128+  82  Linux swap

# mount
/dev/hda5 on / type ext3 (rw)
/dev/hda3 on /boot type ext3 (rw)

I believe that /dev/hda1 is the "Compaq Recovery" partition,
/dev/hda2 is the Windows XP boot, /dev/hda5 and /hdev/hda6
are the logical volumes I created inside /dev/hda4.

Is there any simple way of doing another resize/parted which
can make this setup more like what I originally intended, or
am I basically SOL? (IOW, re-install time?)

If re-install is needed, what is the recommended new partition
layout? (I realize that the answer here is partially a matter
of taste.)
