running mklvcopy was_lv 2 produces the following error

0516-404 allocp: This system cannot fulfill the allocation request.
        There are not enough free partitions or not enough physical volumes 
        to keep strictness and satisfy allocation requests.  The command
        should be retried with different allocation characteristics.
0516-1517 mklvcopy: Failed to create a valid partition allocation.
0516-842 mklvcopy: Unable to make logical partition copies for
        logical volume.

But I can create a new lv "test_lv" and mklvcopy syncvg -l test_lv works.

Got a call open, but wondered if anyone has seen this before?

show [tt]lslv was_lv[/tt] output please?

If UPPER BOUND is set to 1, LVM won't be able to assign PPs on another PV to create a mirror.

Needs at least UPPER BOUND 2 or the default of 32...


HTH,

Thanks P5, I'd just reliased that was the problem, always the simple things that catch me out......

This has caught me a few times too...
These error messages don't give a lot of clues do they?

right.

I had the same problem long time ago. It took some time to fix it in my case.... ;-)
