Hi,
the following Problem,
One of four drives has S.M.A.R.T. errors, so I removed it and
replaced, with a new one.
In the time the drive was rebuilding, one of the three left devices
has an I/O error (sdd1) (sdc1 was the replaced drive an was syncing).
Now the following happends (two drives are spare drives :( )
