Manage RAID 5 is more than verify the container is ok !
You need to be active by checking the disk often for bad block and replace them.
One I got bad block on 3 of a 4disk array another time it was 3disk on an array of 5 and this time
I got lot of corrupted files (with bloc of 4k filled with random value).
Now a check all my disk every month.
Hope this help
Here all my own management script. You can run all these script when the system is running. Of course the disk verify will slow down
the system :-)

Haha. Was too lazy to look at my notes. We currently have 8 servers.
