Hi,
After some minor dramas with one of the disks in my raid1 array deciding to not
be seen by the bios on reboot, I managed to get it back, but had to manually
re-add the partitions to the array. Every time an md device finished resyncing,
I would get this on the console, although things did keep working:
ov 4 14:21:21 tornado kernel: md: md10: sync done.
Nov 4 14:21:21 tornado kernel: md: syncing RAID array md6
Nov 4 14:21:21 tornado kernel: md: minimum _guaranteed_ reconstruction speed: 1
000 KB/sec/disc.

ut not more than 200000 KB/sec) for reconstruction.

ocks.

I noticed a heap of patches out today from NeilB, are these likely to solve this
problem?
