Monthly parity check stated as scheduled this morning. 12:20 pm email notification came as expected and result was pass. 4 minutes later received email notification that disk 6 has 442 read errors. Logged in remotely as I'm at work and see the they are now 44,158 and climbing. Paused parity check and created this post for advice.

    Disk 6 has 3056 reallocated sectors and syslog shows a critical medium error. I would replace the drive. I'm sure one of the resident experts will be by shortly to weigh in with a second opinion.

    Since disk6 has 3056 reallocated sectors I suspect that is probably failing. The syslog shows you are getting ‘critical medium error ’ messages on that disk.
