Extending vg01
Currently 86% of /dev/vg01/lvg011 have been used ..
I wanted to extend the size of the space ...
I did my homework ...
#vgdisplay -v
..
Free PE 249
..
#bdf
..
/dev/vg01/lvg011 8192000 7016990 1101636 86% /mydata
..
the thing is ...
when i tried to "lvextend -L 9188 /dev/vg01/lvg011" in single user mode .. it prompted error message "lvextend : Couldn't query fron LVM device driver the current setting of the logical volume "/dev/vg01/lvg011 : Volume Group not activated" "
Can someone help me with this ??
Can I use the Free PE from vg00 to extend my /dev/vg01/lvg011 ?
Or would i consider on buying new hdisk for this situation ?
Pls advice me on this ...
TQ

Re: Extending vg01
You will need to activate 'vg01' in order to use 'lvextend':
# vgchange -a y vg01
> Can I use the Free PE from vg00 to extend my /dev/vg01/lvg011 ?
No, logical volumes are pieces of a volume group and cannot span different groups.
> Or would i consider on buying new hdisk for this situation
If you have free physical extents in *vg01* then you can enlarge '/dev/vg01/lvg011'. If you don't then you will need to add another (unused) physical volume to vg01 with 'vgextend' before you can 'lvextend' the logical volume and subsequently grow the filesystem within with 'fsadm' or with 'extendfs'.

Re: Extending vg01
vgchange -a y /dev/vg01
BUT...........if your in single user you would probably need to mount up the rest of vg00. OK...Q&A
Q:
1. Does your box have OnlineJFS so you can extend disk live?
A:
Can I use the Free PE from vg00 to extend my /dev/vg01?
>>>>>>>>NO! You can only use disk that belongs to vg01
A: Or would I consider on buying new hdisk for this situation?
>>>>>>>>If you have available space on vg01 disk, then you can use that. Buy storage when you need to or in anticipation of growth.
Hope this helps you,
Rgrds,
Rita

Re: Extending vg01

Activate the vg01 first using this command.
#vgchange -a y vg01
lvextend -L 9188 /dev/vg01/lvg011
Check the syntax of your command. If you are using "L", you specify the size in MB.
lvextend -L 9188M /dev/vg01/lvg011
Can I use the Free PE from vg00 to extend my /dev/vg01/lvg011 ?
