April 7, 20188 yr I almost always seem to worry whenever this has happened in the past. Done stupid stuff like turn the computer off and pull the drive etc, start new config... Anyway, servers still running. Been up and running for about 98 days as it stands. What steps do I need to take now? Looking at the smart self test, I see to get the response: " smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.9.30-unRAID] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org Short INQUIRY response, skip product id A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. "
April 7, 20188 yr Author Seem to have pinpointed when it happened: First line: Mar 28 20:40:42 Tower kernel: sas: Enter sas_scsi_recover_host busy: 7 failed: 7 syslog.txt Edited April 7, 20188 yr by Jawswing
April 7, 20188 yr Community Expert Disk10 drooped offline, possibly because it's connected to a SASLP and those are known to drop disks, but since there's no SMART report for it you need to reboot/power cycle so the disk comes online, then grab and post new diags.
April 7, 20188 yr Author Rebooted, it can do pull a smart report. Currently got a red X at the side of disk 10. tower-diagnostics-20180407-1445.zip
April 7, 20188 yr Community Expert SMART looks fine, you can rebuild to the same disk or if you want to play it be safer use a new disk. http://lime-technology.com/wiki/Troubleshooting#Re-enable_the_drive If it happens again to another disk on the SASLP consider replacing it.
