I wanted to reduce the install to only 100Gb of the drive .
so i searched and found your instructions which ( on a clone of the original drive ) i then proceeded to follow with hope and trepidation .
( i break things :-) ) Booting from a boot CD i get to the last command all has been sweet to that point and it reports "" still in use "" . I want to reduce the Vol Group00 so that i can format the remaining drive for another project.

I had to restore a 17TB filesystem once and that wasn't pretty at all.

Since you can't mount this anymore, you have to run 'fsck' against it. Also, it's a 35gig filesystem so restoring it isn't so bad.
Please visit this page to clear all LQ-related cookies. There is some data already on that partition and I don't want to have to end up restoring from backup. I have never shrunk a filesystem under LVM but I have a 100% success rate when I'm growing it.
In this group there is an lv called RH9 (there are two other lv's in this group that I don't want to touch). The LVM chapter of the Red Hat Enterprise Linux Deployment Guide provides step-by-step instructions for configuring an LVM logical volume using this utility.
I have another volume group called VG_Guests that is completely on /dev/sdb. You can bring up this utility by typing system-config-lvm.
Vol Group00 and the main OS stuff are completely on /dev/sda. edit: forgot gui In addition to the Command Line Interface (CLI), LVM provides a Graphical User Interface (GUI) which you can use to configure LVM logical volumes.

After that I can remount it and it should be the new reduced size. You can bring up this utility by typing system-config-lvm.
What I'd like to try is: resize2fs /dev/VG_Guests/RH9 -15G lvreduce -L -15G /dev/VG_Guests/RH9 Should I go for it or have I missed something? if you are very unsure you should test in vmware first but here is a good read for LVM: forgot gui In addition to the Command Line Interface (CLI), LVM provides a Graphical User Interface (GUI) which you can use to configure LVM logical volumes.
-twantrd Warning: It is crucial that you use the exact amount of space.
If you reduce volume more than the filesytem you truncate the logical volume and you risk data loss! I WOULD NEVER SHRINK A FILESYSTEM WITHOUT A BACKUP !!!
