[linux-lvm] How to increase/decrease space

[Gonyou, Austin]

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.
