October 15, 20187 yr Not sure what happened but my parity drive is off-line this morning and I got an alert- Event: Unraid array errors Subject: Warning [BRUNNHILDE] - array has errors Description: Array has 1 disk with read errors Importance: warning Parity disk - ST8000AS0002-1NA17Z_Z840L3CQ (sdc) (errors 10) Diagnostics attached. brunnhilde-diagnostics-20181015-0719.zip
October 15, 20187 yr Parity dropped offline so there's no SMART report, check cables and/or power cycle the server so it comes back online and post new diags.
October 15, 20187 yr Author Here's the new diagnostics after reboot. brunnhilde-diagnostics-20181015-0810.zip
October 15, 20187 yr Still offline, rebooting might not be enough: 58 minutes ago, johnnie.black said: check cables and/or power cycle the server
October 15, 20187 yr Author Took the array off-line but the drive isn't available to re-assign. I'll check the cables this evening when I get home.
October 15, 20187 yr Author Doesn't look good for this drive. Shutdown the server and replaced the SATA cable with a new spare. When I attempted to boot I got this via IPMI- I was able to reassign this disk as parity though. Parity sync/rebuild is currently in progress. Current smart report and diagnostics attached. brunnhilde-smart-20181015-1623.zip brunnhilde-diagnostics-20181015-1624.zip

When SMART flags on boot, the drive is a goner IMHO. SMART is typically conservative on its recommendation. When it says failed, believe it.

When it says failed, believe it. I don't see anything in the smart report though other than the UDMA CRC error count. I really don't know much about HDD's but it's my understanding that this usually indicates a bad cable.❓ Did I miss something else? Or maybe I'm wrong? Happens sometimes.😄
October 15, 20187 yr Dunno what to tell you. Was that SMART report taken after the image you posted? If so, that's strange, I don't remember ever seeing a drive fail SMART and subsequently pass it.
October 15, 20187 yr That's weird, SMART status bad means there should be a failing now SMART attribute, still disk is showing some issues, mainly: 183 Runtime_Bad_Block -O--CK 063 063 000 - 37 If it fails again I would replace it.
October 15, 20187 yr Author @jonathanm The SMART was taken after the boot up completed. I was surprised by it as well. Running a new one but with the parity sync running it'll take a while. @johnnie.black Thanks. I might go ahead and check the warranty status. Might still be covered.
