I just changed out my old parity drive for a larger one it's syncing.  But the data drives are displaying as Unformatted.  Not right.

 

Also, I'm seeing 57MB/s on the sync.  All drives are 7200rpm.  Does that seem like it's running too slow?

just let it run, or stop the array and start it again until your drives show ok, theyre fine, its all running but the web it justr showing you teh wrong thing. dont ever hit format if it says unformatted and you know its not

 

57MB depends on your disks. older disks are slower than even new green drives.

I know it depends on the disks.  That's why I'm asking.  The drives are all 7200rpm.  I'm thinking it's running slower than it should.

For a parity BUILD that is just fine.  My system will all 7200RPM drives does not average 57MB/s when building parity and that is with all drives on PCI-e buses.  A parity check will run much faster.

There is a big difference in speed of writing to a disk vs. reading from it.  

 

Since you installed a new parity disk it must be written.  That would easily account for a slower speed than if parity was being checked and it was only being read.

Thanks Prostuff1 and Joe L.  That makes total sense.  Adding a new untried disk made me worry unnecessasarily.

Just don't even think of pressing the "Format" button right now.

 

You can stop and re-start the array once the parity calc is completed.  That should get the display in sync.

The parity sync finished, zero errors.  I rebooted for good measure. 

I had exactly the same error when replacing my parity last night. I stopped and restarted the array and all was fine. Parity is now built with a check running.
