The current mirror implementation only supports short-term mirrors, of the sort needed by pvmove. The mirror is destroyed if the device-mapper mirror target is deactivated in any way - including through power loss, or by shutting down device-mapper. Next time the mirror is activated, it again copies the data from the first device to the others. A persistent mirror implementation is under development. Alasdair -- agk@xxxxxxxxxxxxxx
