Description Corey Marthaler 2016-07-21 23:03:26 UTC

Description of problem:
This is a regression of the proper failure "Can't split external origin EXT and pool pool between two Volume Groups."

SCENARIO - [split_thin_extorigin_with_pool_on_diff_pv]
Attempt to split out an external thin volume LV from VG

Create a thin pool, virt, and snapshot volumes in the same vg (different pvs)
Create LV to be used as an EXTERNAL origin device
lvcreate  -L 1G -n extorigin seven /dev/sdd1
Converting LV into an external thin origin device
lvconvert --thinpool seven/pool --originname EXT -T extorigin
  WARNING: Sum of all thin volume sizes (1.00 GiB) exceeds the size of thin pool seven/pool (100.00 MiB)!
lvcreate  -s /dev/seven/extorigin -n snap1
  WARNING: Sum of all thin volume sizes (2.00 GiB) exceeds the size of thin pool seven/pool (100.00 MiB)!
lvcreate  -s /dev/seven/extorigin -n snap2
  WARNING: Sum of all thin volume sizes (3.00 GiB) exceeds the size of thin pool seven/pool (100.00 MiB)!
lvcreate  -s /dev/seven/extorigin -n snap3
  WARNING: Sum of all thin volume sizes (4.00 GiB) exceeds the size of thin pool seven/pool (100.00 MiB)!
