Topic: question about hardware RAID and console message

[idyll]

In building a new box, I ran through the console commands post build and am confused by the following . "only some of the RAID devices are unclean". The console seems to indicate a problem, whereas the result of an mdstat does not.

Can someone help me understand how to interpret this?

thanks

mdstat tells you that /dev/sdb2 has been kicked out of /dev/md2, which is now unmirrored. /dev/md2 contains your data - /dev/md1 is just the boot partition.
