lvextend: Not enough free physical extents available.
"lvextend: Not enough free physical extents available. "
and the my LV is striped LV.so the number of disks selected must match the number of stripes ,in this case 4(i have 4 disk ) but i just wonder why there has 2 disks free space is 0 while the other 2 still has free space .this is striped LV ,the usage should be same right ?while 2 disk still has free space the other 2 no more space .
thanks !

Re: lvextend: Not enough free physical extents available.
If you are looking for a way around you can use lvchange and change the striping
Or use pvmove and move some pv's of other lv's here & there and make room for extending your filesystem

Re: lvextend: Not enough free physical extents available.
How it got to this state is possibly because the logical volume has been extended in the past without the correct parameters distribution policy etc.(I would be interested to see the output of lvdisplay for this logical volume) or you have another logical volume in the volume group.

Re: lvextend: Not enough free physical extents available.
it seems that your LV as a strict PVG allocation or a strict contiguous allocation. You can change it using lvchange :
lvchange -s n /dev/vg02/lvname
lvchange -C n /dev/vg02/lvname
Be careful to be sure that your lv is not mirrored (the lvdisplay must show mirror copies equal to zero).
the lvextend can now be performed.

Re: lvextend: Not enough free physical extents available.
As per vgdisplay you have got 8 LVs. Other LVs might have been created without stripe option. And they will be using the space on /dev/dsk/c16t0d4 and /dev/dsk/c16t0d5.
Is there any swap space configured in vg02?
Do a "pvdisplay -v on /dev/dsk/c16t0d4 and c16t0d5.
cheers

Re: lvextend: Not enough free physical extents available.
Since u have 2 strips, to extend the lv by 10G then it is necessary that u should have atleast 5G free on 2 disks in vg02 ( %g free on each Disk).
