Austine,
I have a hard disk of 4.8GB which i partitioned it into 2 parts (hda1 = 100
meg, hda2 = 4.7gb). The whole disk is of ext3 file system type.The hda2 is
managed by using lvm2. Following is the partition sizes of the hda2 disk;
hda2 VolGrp00 4.6 gb
/ VolGrp00/LogVol00 450 meg 35% used
/usr VolGrp00/LogVol04 1.9 gb 92% used
/usr/local VolGrp00/LogVol05 128 meg 25% used
/home VolGrp00/LogVol03 128 meg 60% used
/opt VolGrp00/LogVol02 128 meg 35% used
/var VolGrp00/LogVol07 450 meg 30 % used
swap VolGrp00/LogVol01 342 meg
Here is sequence of steps that i have performed to inc/dec the partition
sizes;
tried to increase /usr size by 400 meg.
#lvresize -L +450 VolGrp00/LogVol04
when i display using the "lvdisplay VolGrp00/LogVOl04" i see 2.4 gig
allocated to this partition, but when i see it through "df -m /usr" it
hasn't changed.
So, As per Jason's email i have done the below;
#lvextend -L2.4G VolGrp00/LogVol04
But again this hasn't changed my "df -m /usr" output.
I thought using LVM commands one should be able to take care of the inc/dec
of partitions sizes under a given VG. Why should i be using "fdisk" and
"e2fsadm" ?
If i have missed or done any thing wrong while resizing the partitions can
please provide me an example so that i could try it.
Thanks.

That only increases the device size, you also need to extend the partition
onto that larger device. e2fsadm will do it or you can fdisk it to the
larger size. (mind you this involves deleting and recreating the partition
in-memory not on disk, unless you make a mistake and do d 1 w, instead of d
1, then n p 1 <return><return><return>)
Anyhow, you really should look into extending the partition/LV itself now,
depending if you partitioned or not, or used an invalid extent
specification

"lvextend" did not help.
My file system type is "ext3".
Here is output:
#df -m
...
/dev/mapper/VolGroup00-LogVol04 1985 1728 156 92% /usr
...
#lvdisplay VolGroup00/LogVol04
...
LV Size 2.45 GB
...
I did the following on /opt file system for testing, the results were
the same the filesystem did not get increased.
#umount /opt
#lvresize -L +64 VolGroup00/LogVol07
#lvextend -L +64 VolGroup00/LogVol07
Any suggessions.

You've resized the volume but not the filesystem sitting on top
of it. Some filesystems can be resized online while others must
be unmounted. Some may not be resizable at all.
