rollback to command "lvextend"

[guif]

Hi!

I do this command:

sudo /usr/sbin/lvextend -L +2G /dev/VolGroup00/LogVol00

and my Logical volume (LogVol00) are successfully resized but i would like to make a rollback because i don't like to extendend this Volum Group. Is it possible??
(i don't make this command: sudo resize2fs /dev/VolGroup00/LogVol00)

Check out lvreduce.

info lvreduce

or

info lvresize

[guif]

this is the correct command for my rollback:

sudo /usr/sbin/lvreduce -L -2G /dev/VolGroup00/LogVol00

???

Looks right but honestly I don't know I got the commands by looking up the lvextend info and checking the reference to other related function at the bottom of the file. I myself have never actually done it.
