Darren Poh_1 — Tue, 29 Mar 2005 11:21:03 GMT

I run into the this error when i tried to lvextend -m 1 /dev/vgglb /dev/dsk/cztydx

lvextend: Not enough free physical extents available.

this vg is use to have a mirror but this mirror is broken when we vgreduce the disk.

now we trying to mirror it again but runs into the error shown above.

lvdisplay -v

You will probably see the logical volume is set to contiguous and you don't have enough contiguous space on the disk to accomodate it.

Or your split of the original mirror is sittin g on the target disk taking up space.

If its a contiguity issue

lvchange -C n

If the old mirror copy is in the way.

lvremove -f

A backup is prudent prior to taking any action.

Can you do the lvextend without the mirror?

Is it possible that the mirror disk you are using is smaller than the original disk?

If true, you would not have enough PEs available.

Do a vgdisplay -v /dev/vgglb

You need to specify the lvol - not the vg when doing a lvextend...

The vgdisplay will show you your lvols and how much space is available on the disks in the vg...

If you have already done the lvremove, that LV is gone. To get the LV back you would need to recreate it.

lvcreate and lvextend
