I received a reply from LSI: "It seems there is some bad cable or connectivity or bad device in the topology. The loginfo 0x31123000 says the I/O is aborted due to a Stuck Link. The loginfo 0x31120403 specifies the I/O is aborted due to frame transfer errors."So far doing large dd reads and writes, I have been unable to generate any of these errors, it is only during the initial md RAID5 sync up, so I guess this is going to be a little tricky to pin down.
Thanks for the info.There is still one thing I do not understand. I have made a test -- I have connected three SATA hard drives directly to the controller using cable supplied with the controller. The error still occurred. Then I have changed the cable to the one supplied with other controller, as well as hard drives (but model was still the same) and the error message was still occurring.
I have changed controller (I have a few of them) but again, the problem still existed.
The only unusual thing I have noticed during the test, was that all ST31000340NS drives worked at 1.5Gbps, not 3.0Gbps link speed.
I have made plenty of the dd tests and all were fine (both with NCQ and without).
