Re: two questions re. proactive recovery and forced assembly

More information on md RAID options can be found in the file md.txt, in the
Documentation directory of the kernel source.

Looking over md.txt, there is also a less introsive 'check' option,
which it seems does not assume that the array is dirty to begin with.

The documentation says that 'check' "may repair the disk".  What does
that mean?  Will it or won't it?  (does it suffice to use 'check' in a
cron job?)
