lvextend: Not enough free physical extents available.

[Grayh]

yes lvol5 is still empty

[Torsten.]

So lvremove and re-create it (no distribution, not striped).

[Grayh]

wow... thanks Torston... I was able to do that..

Now on my other server

How can I extend lvol5 here... Can I follow the same process

[Torsten.]

This is the host or at least a physical system with hardware mirrored disks.

You have only 10 PEs free - this limits you in extending any LVOL.

[Grayh]

Is it possible to do a lvreduce on any of the other lvols and then extend /home

[Torsten.]

Do you have onlineJFS installed?

[Grayh]

I do not have Online JFS...

May be I will have to go into single user mode and do it

[Torsten.]

Problem is you need to "shrink/reduce" the filesystem before you reduce the LVOL.

How large is /tmp ?

torsten..

/tmp is very large.. So can i go to single user mode and do lvreduce on /tmp and then lvextend on /home

[Torsten.]

IMHO most of your LVOLs are much too large.

You may do an ignite recovery and adjust all sizes when re-installing back.

But you can also consider to delete /tmp in single user mode and recreate it with less size.

DON'T use lvreduce without reducing the filesystem first!

Thanks everyone
