[dm-devel] Re: Desynchronizing dm-raid1



No other driver than dm-raid1 has problems with this and they wouldn't damp performance because of one driver.

--- so I found that md-raid-[156] recently (2.6.13 or so) added a bitmap mode and when this is used (argument --bitmap to mdadm), it is vulnerable to this desynchronization bug too. Before, it synced the whole device when it crashed without shutdown, so it was OK.
