The recovery *starts over*, as if nothing had happened over the last hour or so. The event counter are very close between /dev/nbd0 (the device here) and /dev/sde (the core device), within a dozen or so, but the "dirty percentile" on /dev/nbd0 is big - 18.8%, and unchanging between runs. It's like the bitmap isn't getting updated, or getting updated incompletely, or something. Does the bitmap only get updated when *all* devices have sync'd??? I'll let you know in about 2 hours.
The bitmap never gets cleared unless all disks in the array are in sync. -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
