[ILUG-Cochin.org] deleting an unused sandwich partition without trouble

[Sebin Jacob]

Hi,

I have a peculiar partition problem that should be dealt with. My partitions
are as follows:

Primary partitions

/dev/sda1  Windows TYPE="ntfs"
/dev/sda2 Linux boot partition TYPE="ext2"
/dev/sda3 Windows  TYPE="ntfs"

Extended partition

/dev/sda4

Logical partitions

/dev/sda5 ntfs
/dev/sda6 linux swap
/dev/sda7 lvm2pv over dm_crypt

The encrypted partition /dev/sda7 is aliased as physical volume
/dev/mapper/vgroup . The volume groups is partitioned as follows.

/dev/mapper/vgroup: TYPE="lvm2pv"

/dev/mapper/vgroup-root:  TYPE="ext3"
/dev/mapper/vgroup-swap: TYPE="swap"
/dev/mapper/vgroup-usr:  TYPE="jfs"
/dev/mapper/vgroup-var:  TYPE="reiserfs"
/dev/mapper/vgroup-opt:  TYPE="xfs"
/dev/mapper/vgroup-tmp:  TYPE="xfs"
/dev/mapper/vgroup-home:  TYPE="ext4"

when mounting the partitions, swap is mounted from the lvm,
/dev/mapper/vgroup-swap. I accidentally had kept a separate swap partition
outside the logical volume which is of no use now. It comes around 1.7 GB,
ie, 15% more than my RAM. I wanted to merge it with /dev/sda5, the ntfs
logical partition inside the extended partition. But normally, if i do so,
the encrypted partition /dev/sda7 will be automatically renamed as
/dev/sda6. As /dev/sda7 is currently a linux logical volume, this may create
a problem with booting my distro: Arch linux that I had build from base
(using kdemod4 as DE). So is there a way out to successfully delete
/dev/sda6 and merge it with /dev/sda5 without causing trouble to my GNU
system? If I specify partitions with its UUID is fstab, can I succeed in
doing so? Otherwise, it would take 2-3 days downloading installing and
tweaking the system for my use.

regards,
Sebin
