Doc Text:
dm-era Technology Preview The device-mapper-persistent-data package now provides tools to help use the new dm-era device mapper functionality released as a Technology Preview. The dm-era functionality keeps track of which blocks on a device were written within user-defined periods of time called an era. This functionality allows backup software to track changed blocks or restore the coherency of a cache after reverting changes.

Description Steve Almy 2013-12-04 16:51:09 UTC 
In order to improve performance for both physical and especially virtualization deployments we'd like to backport dm-cache from upstream/rhel-7 into RHEL 6 - ideally for RHEL 6.6
Comment 1 Heinz Mauelshagen 2014-02-19 13:46:27 UTC 
dm-cache userspace components (cache_check, cache_dumo, cache_restore, cache_repair) added.
