[linux-lvm] disk info

[Valentine Kouznetsov]

Hi,
I'm newbie of using LVM. I'm having the following "strange" behaviour:
I can lvextend my volumes, but I cannot see the changes using df
command. Actually df output is different from LV size of lvdisplay
output. Is it known bug and/or I'm missing something.

My configuration:
RedHat 9, kernel 2.4.21 or 2.4.20-19-9 (from RedHat), lvm-1.0.3-12 (from 
RedHat 9)

I would appreciate if you cc me to vk@mail.lepp.cornell.edu

Thanks,
Valentine.

you have to resize the filesystem on the lvm lv
after you extended it ...

for ext2/ext3 this would be resize2fs ...

Herbert,
thanks for tip. I've look at resize2fs, but at least for ext2/ext3 I
need to unmount my partition first. How about situation if root partion
is on LVM and I want to resize it as well.
Thanks,
V.

there are some effords to resize a fs while mounted,
but usually the procedure is the same, and you either
boot from a rescue cd/floppy or a special rescue 
partition ...

It sounds like you're not extending the filesystem after you've extended
the volume.

well, in that case you need to boot of a floppy, cdrom or something else
which provides you all the tools you need. Why on the first hand did you
install root on an lvm? I for my part don't see the need. My root is
about 75 mb, with everything else (/usr, /var, /home) on seperate
partitions.
