Now to increase lvol5... can i use the the following

and then
lvextend -L 51200M ....
vgextend...

You only have 1732 extents avail, @ 8MB an extent that is about only 13GB. YOu are trying to grow this to 51GB.

You DO NOT have enough storage in thie VG to satisfy your request.

The max you can do would be close to.
lvextend -L 13000 /dev/vg00/lvol5
or
lvextend -l 1732 /dev/vg00/lvol5

This machine is a VM Guest

and now I was successfully able to extend lvol5 to 12g

Now is there a way I can extend this even more

from your first post:

# vgdisplay -v

Note PE Size (Mbytes) is 8. Free PE 1732. As noted above, thats ~ 13GB. IT IS NOT GOING TO WORK when you attempt to add 51GB.

It will work for sizes less than 13GB (as you found when you were able to extend it by 12)

I have extended it to total 13 GIG .. Is there a way I can extend this to 50GIG

I see that there are only 81 free PE avaliable... Is there a way I can add more PE's So that I can have 30G for /home.I have two disks one is 10G and the other is 40G.

Now how can I increase the /home from 13G to 35G.

Andres_13 — Mon, 20 Oct 2008 20:04:41 GMT

I just don't understand above post.

If you want to increase the size of that lv up to 51gb you must add a LUN to it's VG to met that requirement, that's the only way I know.

Regards!

Re: lvextend: Not enough free physical extents available.

Andres_13 — Mon, 20 Oct 2008 20:07:07 GMT

You need to vgextend and add the 40 gb disk to your vg00..... because with only 10 it wont be enough.

Regrds!

Re: lvextend: Not enough free physical extents available.

Tim Nelson — Mon, 20 Oct 2008 20:13:17 GMT

Your 35GB disk is alreay in vg00 and almost completely used.

The 10GB disk, if not used, could be added to vg00 and then you can add 10GB to which ever lvol you wish but it still will only take you to 26GB if you add it all to lvol5.

pvcreate /dev/dsk/c0t0d0
vgextend /dev/vg00
lvextend -L 26000 /dev/vg00/lvol5

If you wish to get to 30GB or more then you MUST add more virtual disk to the vGuest.
(not sure why you want to make the /home filesystem so big, but to each their own )

Re: lvextend: Not enough free physical extents available.

Grayh — Mon, 20 Oct 2008 20:15:15 GMT

Sorry I want to extend lvol5 to 35Gig ... not 50Gig... It was a typo...

how can I do that..

Re: lvextend: Not enough free physical extents available.

Tim Nelson — Mon, 20 Oct 2008 20:24:21 GMT

You MUST create a larger backing store on the vHost and present it to the vGuest.

The two you have presented (35GB and 10GB) are not enough.

Pls consider assign points.

Looks to me like a HPVM guest, right?

Please clarify!

Do you want to extend the lv on the guest?

What kind of backing storage do you have? LVOLs?

Re: lvextend: Not enough free physical extents available.

Torsten. — Tue, 21 Oct 2008 11:58:57 GMT

If I **assume** you want to extend the lvol of the guest and you have enough free space, the reason for the error is this setting for lvol5:

...
Allocation strict
...

Change it and it will work!

Re: lvextend: Not enough free physical extents available.

Grayh — Tue, 21 Oct 2008 12:01:15 GMT

yes it is a HPVM ... I have 2 HPVM's on this server and on both of them to have to increase /home to atleast 13GB. There is no External Storage avaliable
