I couldn't fine serial numbers for the parity drives, but found them now, it says parity will be over written.

If you are SURE all array drives are arranged EXACTLY as they were, you can safely select "parity is already valid" and just do a parity check.

I did that last night, not done a parity check yet.

Everything seems to look fine.

Now the system looks like it's up and running, when I do a parity check and if it finds any errors which data gets changed?

Parity 1 data

Parity 2 data

Or array data

Thanks all.

Non- correcting parity checks don't change anything, they just report inconsistencies. Correcting parity checks change the parity disks to match what is on the data disks.

 

You NEED to verify your parity NOW, since you just did a major change. If parity is invalid and you have a write failure and a disk is red balled, you will lose data. By checking the box saying parity is valid, you put yourself at risk until parity is actually checked valid. It probably is, which is why I told you to check the valid box, but you need to run a check to confirm.

Thanks will do that.
