kennexdewa Posted March 15, 2018 Share Posted March 15, 2018 So i woke up this morning to find my parity disk has been disabled. Have gone through logs and conveniently there is no SMART report log for my parity drive, however when manually conducting a SMART test on the drive it passes with flying colours. I've attached my logs if some one could decipher them for me please. Thanks in advance, Regards Kennex unraid-diagnostics-20180315-2147.zip Link to comment
wishie Posted March 15, 2018 Share Posted March 15, 2018 I'm no expert, but it looks like a bunch of 'drive not ready' errors, followed by a heap of write errors.. I had a similar issue a while back, and in my case, it ended up being a power supply issue.. did your system recently try to do a parity check by chance? Link to comment
wishie Posted March 15, 2018 Share Posted March 15, 2018 lots of this in syslog: Mar 10 00:53:14 unRAID kernel: sd 4:0:2:0: [sdd] tag#1 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 Mar 10 00:53:14 unRAID kernel: sd 4:0:2:0: [sdd] tag#1 Sense Key : 0x2 [current] Mar 10 00:53:14 unRAID kernel: sd 4:0:2:0: [sdd] tag#1 ASC=0x4 ASCQ=0x0 Mar 10 00:53:14 unRAID kernel: sd 4:0:2:0: [sdd] tag#1 CDB: opcode=0x8a 8a 00 00 00 00 00 74 70 8e 38 00 00 00 08 00 00 Mar 10 00:53:14 unRAID kernel: print_req_error: I/O error, dev sdd, sector 1953533496 followed by lots of: Mar 10 00:54:06 unRAID kernel: md: disk0 write error, sector=2091053720 Mar 10 00:54:06 unRAID kernel: md: disk0 write error, sector=2091053728 Mar 10 00:54:06 unRAID kernel: md: disk0 write error, sector=2091053736 Mar 10 00:54:06 unRAID kernel: md: disk0 write error, sector=2091053744 Mar 10 00:54:06 unRAID kernel: md: disk0 write error, sector=2091053752 Link to comment
trurl Posted March 15, 2018 Share Posted March 15, 2018 Check connections, then post a new diagnostic so we can see SMART for parity. You will have to rebuild parity of course, but it would be better if we could see the SMART to make sure the disk is OK, and you need to have a reliable connection anyway for the rebuild.

wishie Posted March 15, 2018 Share Posted March 15, 2018 Yeah, I should have mentioned, check power and sata cables first.. replace if you think you need to. I did all of that, but mine ended up being the power supply not providing nice clean power when all disks spun up for a parity check. Link to comment
kennexdewa Posted March 21, 2018 Author Share Posted March 21, 2018 Hi all, apologies for the delay in replying. I'm running an EVGA 750W G2 power supply, just swapped out power and sata cables and re-run the SMART test. Unforuntately error still occurs. Attached are the results.

You only did a short SMART test, you should run an extended test, especially since there are a lot of reallocated sectors: 5 Reallocated_Sector_Ct PO--CK 100 100 010 - 1112 If it passes the extended test and you want to keep using it you need to re-enable the disk and re-sync parity. http://lime-technology.com/wiki/Troubleshooting#Re-enable_the_drive Link to comment
trurl Posted March 21, 2018 Share Posted March 21, 2018 I would replace it with that many reallocated Link to comment
