Resize fs online

[7280]

Hi,
I'm using redhat advanced server 4 upd 2 64 bit and I want to resize /opt filesystem online.
Searching the web I found that this is possible by issuing two simple commands (if there's unallocated space in the volume group).
Commands are:
lvextend -L +sizeM /dev/VG/LV, so:
lvextend -L +32M /dev/vg_root/lv_opt
ext2online /fs, so:
ext2online /opt

I tried it on my virtual machine and it seems ok but I'm afraid to do it on production.
Does anyone tried these commands before?
My filesystem is ext3 (not ext2) but the command seems ok also for this filesystem type.
I followed this document:

http://kbase.redhat.com/faq/FAQ_85_4841.shtm

Any help is appreciated.

Thanks in advance.

during my RHCE course they recommended to backup you filesystem anyway before using lvextend.

I have done it succesfully several times but each time I do a nice tar backup before.

If I could have sex each time I reboot my server, I would definitely prefer Windoz over Linux!
