Over the week end I got 4 read errors on one of my drives 
It is one of the older drives in the system with 30273 power on hours (WD Red 6TB)

Has since passed a extended smart test and no more errors

Following error in syslog looks to me more like a disk problem than cabling (which has not been touched/moved in 6-12months)

Thinking I should still swap out the drive?  thoughts?

Prefer not to as there is too much private information included them (eg file names, IPs etc in log files) even with anonymize on
What specific information do you want?
