Description Corey Marthaler 2009-05-26 20:27:32 UTC 
Description of problem:
Saw this while verifying bug 477040. If your VG has an extent size of only 1K, and you don't specify any space for the log ( :0-0 ) then you'll see this assertion.

[root@grant-03 ~]# vgcreate -s 1K grant /dev/sdb1 /dev/sdb2 /dev/sdb3 
  Volume group "grant" successfully created

[root@grant-03 ~]# lvcreate -L 64M -m 1 -n mirror grant /dev/sdb1 /dev/sdb2 /dev/sdb3:0-0
lvcreate: metadata/pv_map.c:190: consume_pv_area: Assertion `to_go <= pva->count' failed.
Aborted (core dumped)

This is reproducible.

I sent some patch here
https://www.redhat.com/archives/lvm-devel/2009-May/msg00220.html

(I cannot reproduce segfault, but it should not reach assert code anyway).
