Thanks Nicoya, It worked. I was able to reduce my root "/" file system size, following the instructions in http://www.balug.org/pipermail/balug-talk/2002-April/000310.html . but had to perform three additional steps; (a) disable "/" fs mount in "fstab" (b) reboot using rescue CD, and perfrom (i) resize2fs, (ii) lvreduce (c) mount the "/" fs and change the "fstab" to enable "/" fs mount and reboot. thanks for everyone help.

That part I don't have experience with, but obviously the first step is to reduce the amount of actual data on the FS so that it is less than the size you want to shrink it to. If you are using LVM 1, you can use e2fsadm to shrink the LV and the FS in one step, but there is no e2fsadm for LVM2 . For LVM 2 you have to do the 2-step resize2fs and lvreduce as described in this post to another list: http://www.balug.org/pipermail/balug-talk/2002-April/000310.html >While increasing the space on a LV, Do i need to do lvresize, lvextend, >resize2fs or just lvextend and resize2fs ? You should only need to do lvresize _or_ lvextend, then resize2fs.
