extendfs on root

Chris Frangandonis — Fri, 20 Dec 2002 23:55:12 GMT

Hi

I have a root disk which was a 2g, which I increased it to 4G with ignite. There are 3 vol groups which are /dev/vg00/lvol3 as "/",and dev/vg00/lvol1 as "stand", dev/vg00/lvol2 as swap.
I have lvextend lvol3 to 2.5G, and tryied to extendfs -F hfs, but with not luck. Is it possible to increase lvol3 to show 2.5G

Many Thanks
Chris

Why do you want LVOL3 to be 2.5G? That is awfully large for the / partition.

The easiest way to do that would have been when you put the 4G disk in. You used ignite so you could have just modified the LV sizes when you were there.

Hi Patrick,

Thanks ,but it was 1,6G and inorder for my to load our Dec Patches as well as our software maintance release, it goes up to 97% on /. I did increase the lvol3 with ignite but no success. Is it possible to re-ignite the disk and change values?.

Yes, it is possible to reignite your system and change the values.

It sounds as if you have one giant / volume. The root volume cannot be extended as every extent must be contiguous. You'll have to use Ignite to rebuild lvol3.

However, a large / volume is VERY non-standard. /tmp, /var, /opt, /usr and /home are usually separate volumes. The / volume needs to be only 100 to 300 megs. Things like patches and installed programs should never go into /.

Hi Gents,

Thanks for all u help. I did ignite it and succ increased it . My problem was that I forgot to modify it.
Bill: "/" consits of var,opt,sbin,tmp,usr on one logical vol and /stand on another (lvol1). It was create by DD years ago, I dont know why!.

What would we "dummies" do without ITRC forums.

Once again thanks
Chris
