My current setup is:

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2894    23246023+  83  Linux
/dev/sda2            2895        3381     3911827+  82  Linux
   swap /Solaris 
/dev/sda3            3382       24804   172080247+  83  Linux
/dev/sda4           24805       30401    44957902+  83  Linux

where sda3 is an lvm volume and sda4 is free space.

I'd like to to merge sda3 and sda4 into a single partition without
losing the data on it, but I'm not sure if it is possible.

My guess is that I can use fdisk to delete sda4 and sda3, create a sda3
partition starting at 3382 and ending at 30401, then use pvresize to
enlarge it.

This is from man pvresize:
"Expand the PV on /dev/sda1 after enlarging the partition with fdisk:
pvresize /dev/sda1"

Is that going to work or I'm going to lose all the data?

P.S. I'm not using vgextend to simply add sda4 to the lvm because I
might want to migrate my root (sda1) to ext4, and to do so I will need
to split it in two separate partitions (/boot using ext3 and / using
ext4). This way I'm not going to need extended partitions.
