June 12, 201511 yr I just got the following disk read errors yesterday. Are these a concern? Where do I go from here?

June 12, 201511 yr Author Post complete syslog and smart reports for the drive. Here's the syslog. By smart report you mean what exactly? I'm currently running an extended smart test on the drive now. Short test passed without errors. syslog.txt
June 12, 201511 yr Looks like your syslog rotated. See if you have any others in /var/log. From Main, click on the disk, then Health - Attributes and post that while you wait on the long test.

That's the only one I see in the /var/log directory. Here are the attributes for the disk showing the read errors.

Looking at the syslog you posted again, I see that it is from Jun 2Jun 2 18:15:49 SPE-UNRAID-BCKP rsyslogd: [origin software="rsyslogd" swVersion="8.6.0" x-pid="1143" x-info="http://www.rsyslog.com"] start Go to Tools - System Log and post that one instead.

That's where I got the one I posted. It starts at June 2nd but you'll see it goes up until today. I just checked and my date was off. My server has today as being June 11th. Just fixed that by turning on NTP.

The online SMART tests are not going to help you. So...what now? Send the disk for RMA?
June 13, 201511 yr You could try power cycling the drive to see if it reports any out of range spin up times. But as a one off, I'd wait to see if the problem reoccurs in this drive or another. It's as likely to be a power supply as the disk drive with only one report.
