[linux-lvm] Error setting up a mirrored lv



Hi,

i'm doing this:

>> hgest3301:~/LVM2.2.02.06 # lvcreate -m1 -n lvmirror -L 10G 
>> vgtest /dev/dm-55 /dev/dm-56
>>   Not enough PVs with free space available for parallel allocation.
>>   Consider --alloc anywhere if desperate.

here are the pvs?

>> hgest3301:~/LVM2.2.02.06 # pvs
>>   PV         VG          Fmt  Attr PSize   PFree

what's wrong? 
Is there any documentation out there?
Why do we need three pvs? for a mirror?
Are there any other options?
