Is there a way to forcibly mark a RAID1 as clean? I know it can be
dangerous, I just don't want to wait for 200GB of scrap to resync.
For some reason, the resync is terribly slow in Linux 2.6.0, only
~1MB/s. DMA is enabled on all disks and the individual performance of
each disk is normal. There are no error messages from the kernel. It
just doesn't seem right.

2.4.18 here and I'm also getting about 1MBs/sec on resynch. :(

Hi
Do you increment the values in /proc/sys/dev/raid?
(Hope it´s still there in 2.6.x)

I did, and the problem went away. Now it's 40 MB/s.
