There is a problem with the driver, card, cables or disks, etc. The Areca probably has problems with JBOD mode (I was unable to get a different Areca RAID card to work reliably in JBOD mode this spring so I'm not surprised). If these are SATA drives try a card using the Silicon Image 3124 controller and the SIIS driver: for SAS try the LSI 3801e or 3081E-R cards. > $ ssh back02 zpool status > pool: back02 > state: ONLINE > status: One or more devices has experienced an error resulting in data > corruption.
