Alex.vision Posted February 27, 2021 Share Posted February 27, 2021 (edited) Hey Yall, I woke up to an email from my Media Unraid server: Event: Unraid array errors Subject: Warning [MEDIA] - array has errors Description: Array has 1 disk with read errors Importance: warning Disk 15 - ST8000DM004-2CX188_WCT0NR2S (sds) (errors 4) I logged into the server this morning while at work, and saw that one of the drives was marked at fault with (4) errors. Not knowing what the error was, I shutdown the server until I was home later and could diagnose. I can home and pulled the flash drive and looked at the system log. Starting at line 161 I see a kernel: nginx[6821]: segfault, followed by some TRIM status logs, then the stopping of the mover script. I see some other information that I don't understand at all, until I reach line 181. That's when I see this: Feb 26 04:45:43 Media kernel: md: disk15 read error, sector=576031088 Feb 26 04:45:43 Media kernel: md: disk15 read error, sector=576031096 Feb 26 04:45:43 Media kernel: mpt2sas_cm1: removing handle(0x000b), sas_addr(0x5001940000dd8201) Feb 26 04:45:43 Media kernel: mpt2sas_cm1: enclosure logical id(0x5001940000dd823f), slot(1) Feb 26 04:45:43 Media kernel: md: disk15 write error, sector=576031088 Feb 26 04:45:43 Media kernel: md: disk15 write error, sector=576031096 I am not sure of the difference between read errors and write errors, I think I have only ever experienced Pending Sector Count and Reallocated Sector Count errors. I honestly don't remember the last failed drive I had with Unraid, so I wanted to upload my syslog and diagnostics for some advice, should I replace this drive, could this be connection related and maybe reseating the drive in the caddy could fix it? I know this drive like all of my other ones are at between 98-99% full, I don't remember what the minimum free space was for that share, but I think it was around 20GB, and I know the mover was running right before the error but I think I was transferring 1-2GB files around. I don't think it would have filled up the drive, I don't even know if that would cause a drive error, I'm just throwing out the info. Anyways, I would appreciate any advice on this issue. Thanks for the help. -Alex Alex.vision-Media-Syslog-2021-02-26.txt media-diagnostics-20210226-0957.zip Edited March 1, 2021 by Alex.vision Quote Link to comment
JorgeB Posted February 27, 2021 Share Posted February 27, 2021 Disk dropped offline, change/replace cables to rule them out see if it happens again to the same disk, disk will need to be rebuilt. Quote Link to comment
Alex.vision Posted February 27, 2021 Author Share Posted February 27, 2021 Ok, the drive is in a DAS unit, so I can move it to another slot. I will give that a try. Thanks Quote Link to comment
