Hi,
Neil Brown recently explained on the linux-raid ML that one can do
partial checks on a raid array:
| If you first read from 'sync_completed' and store that value,
| then before starting a new 'check', write the value to
| sync_max, then you get exactly what you are asking for, all
I assume he ment sync_min here.
| easily done in a shell script.
| You can also set 'sync_max' if you like, thus you could e.g.
| quite easily have a cron job that scrubs 1/28th of the array each
| night based on the day of the month.
I think it would be a good idea to change the default check to run
like this, a little every day or week with /etc/default/mdadm saying
which of the two.
MfG
Goswin
