Description

I have the ASRock Motherboard C2550D4I. Ever since I have been using this board I get periodic Smart Read Failures when I do a smart check, but from what I can tell its only from the 6GB channels on the motherboard. I have swapped hard drives however it doesn't seem to matter what drive I'm using. I have had this problem since 9.2 when I initially installed FreeNAS.

I've looked through the debug info provided, but unfortunately I can't find there much about the problem you are talking about. As I can see, this system includes 6 Intel SATA ports (2 6Gbps and 4 3Gbps), 2 6Gbps SATA ports on one Marvell HBA and 4 6Gbps ports on another Marvell HBA with fancy RAID firmware, reporting 8 ports. Considering that SMART error mentions ada4 disk, my best guess is that something goes wrong with the second Marvell SATA HBA. Considering that it happens only sometimes and only for SMART, I guess it is quite rare. Unfortunately to debug anything there I need much more information, and better easy scenario to reproduce it. And even in that case, there is no much believe that it is not an another bug with that fancy RAID firmware of that chip.

I would recommend you to move as much disks as possible to Intel SATA ports (as fast and more reliable ones), and between Marvells I would prefer the non-RAID one. Unfortunately you have not enough ports for your 10 disks to completely avoid second Marvell HBA. If you plan to expand at some point above you present 10 disks, you could consider going into higher league and start using proper LSI SAS HBAs, potentially combining them with some number of Intel SATA ports, if needed.
