Ok, this is actually embarrasing. I know I've done this before, and I actually thought that I just did it, but I guess not. I'm having a problem resizing a LV in 4.3.3. when I issue a df -k I get

Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 114688 97408 16% 1361 3% /
/dev/hd2 1671168 349200 80% 26432 7% /usr
/dev/hd9var 65536 9272 86% 902 6% /var
/dev/hd3 65536 52304 21% 308 2% /tmp
/dev/hd1 16384 15648 5% 70 2% /home

Then if I issue an extendlv hd2 10 to add 10 more PPs the command works fine, but my free space does not increase. However an lsvg -p rootvg shows that the volume size has increased by 10 PPs. Am I missing a step? I can't seem to find it anywhere. I've tried Google, this forum, and Redbooks.

Any help would be awesome.

Thanks!

if you want to increase the "/usr" file system you can use :

chfs -a size=+1 /usr
by this well increase the "/usr" by 1 LV.

The easyest way to do that is using smit.
simply type :
smit fs
change a filesystem
choose the fileystem name
choose the new size.
that's all.
You have to change the filesystem size, and not the size of the logical volume underneath. Changing the logical volume size did not change the filesystem above size.
