[linux-lvm] Problem resizing partition

[-- Attachment #1: Type: text/plain, Size: 1429 bytes --]

Hello. I have recently installed a CentOS 5 Linux distribution. Is a free
version of Red Hat Enterprise.

I are a Linux Newbie.

The Linux installer DVD does not liked the 20 Gb ext3 partition I have
created (It was saying than now enough space was available), so I tell him
to automatically configure the partitions and filesystem.

The Installer formatted and created a 32 Mb "boot" partition, and a 20 Gb
"unknown" partition (as is found By gparted software).

I need to reduce this "unknown" partition by 8 Mb, (to avoid writing the
last 8 Mb, since is probably that the PC vendor, has utilized this space to
hide information, that windows use to recognizing that is "genuine", (don't
bash me about windows, I have not purchased that machine, I are utilizing
that machine to experiment and learn Linux, because I want latter to operate
a cluster with that OS, and I can't do experiments on the cluster, like
learning to resizing partitions)

I have not idea what file system is, and what tools allow to resize that
partition. I Have installed gparted (#yum install gparted), since I was told
that is the "Partition Magic" of Linux.
but It looks like this file system is rare, because is for cluster designed.

Looking on Internet, I have found that probably this system utilizes clvm
(no idea), so I have found this mail list, and write for help.

can you help me?

PD:Please, excuse my bad grammar, I never studied English.

hi, 
According to your  description you want to decrease a partition, so you 'll need to umount your file system an d change the size, with fdisk or gparted.
After that remount your partition.

Thanks for your answer!.

I was unaware that That partition was needed unmounted.

¿I can unmount the main Linux Partition, start gparted, and then remount
it?, or I need a Live CD?

I have the Puppy Linux Live CD, and I have burn the Gparted Live CD. I gonna
try to use them.

Re: [linux-lvm] Problem resizing partition

[marraco]

Solved. LVM uses pvresize command to change physical partition size...

It is in the manual. 

For a graphical interface, is necessary to install system-config-lvm
In CentOS 5 is in the package:

system-config-lvm-1.0.22-1.0.el5
