Jon: always nice when computers act like finite-state machines, not like
incomprehensible organic devices.
Tejun: thanks again.
Cheers,
Bruce

Thanks Bruce and Tejun,
I have replaced the hot swap drive tray of the drive in question,
rebooted and reinstalled the latest version of smartmontools. So far I
have read and wrote about 50GB of data to the raid array over the last
18 hours with smartd running and have not seen any kernel error
messages. Looks like the interconnect was at fault.
Thanks again for the help,
Jon

Subject: Re: sata_sil24 with port multiplier
All errors are interface CRC errors reported by device on FPDMA_WRITE.
It doesn't seem to have anything to do with SMART. In all cases,
SError
DIAG is reporting handshake error too (R_ERR received). I'm fairly
sure
these were actual hardware problems. You don't have to pay too much
attention unless it happens repeatedly. Good cure for the problem is
probably to re-seat the harddrive.
Jon: as Tejun says, the ICRC errors indicate a problem with the data
cabling or connections between the drive and the controller. Replug,
clean, examine (and perhaps replace) SATA cables and/or connectors. The
SMART error log (smartctl -L) might also show entries for the ICRC
errors
(with timestamps that might be useful).
Bruce, I don't think this is SMART related. Sorry about the noise.
Thanks.
Tejun: thank you again, no worries, and definitely no apologies needed!
Cheers,
Bruce
