Hi, every one:
I have a question about how to repair raid5.
Days ago, I received a email from the monitor of mdadm.
The email told me that there were lots of mismatch_cnt in the array.
Then I tried to find the solution of this problem on Google. Most solutions were as the following:
#echo repair /sys/block/md0/md/sync_action
#echo "check" > /sys/block/md0/md/sync_action
#cat /sys/block/md0/md/mismatch_cnt
I did repair the array like the above.
But I found that it took lots of time to "repair" and "check" the array.
Why there was a "check" after "repair"I did not know. And it spent as much time as "repair".
Is it redundant? Anyone can help me?
