Description Heinz Mauelshagen 2014-04-03 14:51:39 UTC

Description of problem:
device-mapper-persistent-data needs new userspace tools to support
the new dm-era target supporting dm-cache coherency with storage
subsystem snapshots. E.g. to invalidate a certain era refering to
a hardware snapshot.

Version-Release number of selected component (if applicable):


How reproducible:
if using the dm-era target, no tools exist to e.g. invalidate any
eras or check the era metadata.

Steps to Reproduce:
1. setup dm-era mapping
2.
3.

Actual results:
Mapping created but no tools to actually set eras.

Expected results:
Tools available to set eras
