since upgrade to 6.10 RC7 getting failed command: READ FPDMA QUEUED

[MrLondon]

Hi there,

 

I can see in my syslog lots of these error message

is this from the SAS controller or a specific drive? any help greatly appreciated.

if I understand the logs correctly it appears to affect my first parity disk, do I understand this correctly? ata2.00: ATA-9: WDC WD140EDFZ-11A0VA0, 81.00A81, max UDMA/133

Looks more like a power/connection problem, check/replace/swap cables on parity2.
