Operation continuing on 0 devices Oh dear, that array isn't much good any more.! That is the second report I have had of this with sata drives. This was raid456, the other was raid1. Two different sata drivers are involved (sata_nv in this case, sata_uli in the other case). I think something bad happened in sata land just recently. The device driver is returning -EIO for a write without printing any messages.
