lvextend: Not enough free physical extents available

[Mohamed Galal]

I started extending my VGDB because it is 90% full. But I tried to execute the below procedure. But during executing the command <<# lvextend â l 5000 /dev/vgdb/lvol1>>, it gave the following error:

naclds:/ (167) root% lvextend -l 5000 /dev/vgdb/lvol1
lvextend: Not enough free physical extents available.
Logical volume "/dev/vgdb/lvol1" could not be extended.
lvextend: Couldn't retrieve the list of the physical volumes
belonging to volume group "/dev/vgdb".
Failure possibly caused by strict allocation policy

Hi,
as of your lvdisplay the lv is stripped accross 4 PV's. so for extending the LV you need to hav free PE's on another 4 PVs.

Thanks,
Shanmugam.

Salam,

In vgdisplay 1998 PEs are free. So

Plz post output of below command.

#uname -a
#model
#pvdisplay /dev/dsk/c4t0d1
#pvdisplay /dev/dsk/c4t0d2
#pvdisplay /dev/dsk/c4t0d3
#pvdisplay /dev/dsk/c4t0d4

Are you using mirroring.

#lvdisplay -v /dev/vgdb/ (Full Output)

After dividing the new luns to be 4 luns & forcing the LV tobe extended.
