support of LVM in Mac Os X??????

[jacek]

...like in linux and windows there is named LVM ...

LVM isn't just a tool that resizes partitions. It takes control over your physical disks and crafts virtual ones to your liking.

PLEASE DO TELL ME IF IS THERE ANY WAY TO EXTEND OR MERGE OR RESIZE(NOT SPLITING ONLY INCREASING THE SIZE) COOMAND ON MAC OS X 10.4

According to Google parted should be able to do it (http://lists.apple.com/archives/X11-.../msg00055.html), but you can resize only the third partition.

And please don't shout.
