Jonathan Brassow	ee89ac7b88	pvmove: Disallow pvmove of cache LVs Skip over LVs that have a cache LV in their tree of LV dependencies when performing a pvmove. This means that users cannot move a cache pool or a cache LV's origin - even when that cache LV is used as part of another LV (e.g. a thin pool). The new test (pvmove-cache-segtypes.sh) currently builds up various LV stacks that incorporate cache LVs. pvmove tests are then performed to ensure that cache related LVs are /not/ moved. Once pvmove is enabled for cache, those tests will switch to ensuring that the LVs /are/ moved.	2014-02-24 12:25:18 -06:00

pvmove: Disallow pvmove of cache LVs

Skip over LVs that have a cache LV in their tree of LV dependencies
when performing a pvmove.

This means that users cannot move a cache pool or a cache LV's origin -
even when that cache LV is used as part of another LV (e.g. a thin pool).

The new test (pvmove-cache-segtypes.sh) currently builds up various LV
stacks that incorporate cache LVs.  pvmove tests are then performed to
ensure that cache related LVs are /not/ moved.  Once pvmove is enabled
for cache, those tests will switch to ensuring that the LVs /are/
moved.
