integrity verification on raid-5?

["Patrick H." <linux-raid@xxxxxxxxxxxx>]

Is there a way to do integrity verification on a raid-5 array? I'm 
working on building a storage system on SSDs under raid-5 and want to be 
able to perform periodic integrity checks. Basically just check the 
drives to make sure that they match what the parity drive has.
After a bit of googling I saw other people wanting the same thing but 
nobody with any result. I dont see why this cant be done, but is there 
any tool to do so?
