ArdNsc Posted December 26, 2022 Share Posted December 26, 2022 If this is the wrong Sub-Forum, please just hint me into the right direction. Over a year ago Unraid reported a SMART-Error for one of my SSDs in my cache-pool. I confirmed the warning and since then no new errors where reported. Now I realised that I cannot run manual short or extended SMART-tests anymore (when I click, just nothing happens). There is no really important data on my Cache-Pool, which is running as a btrfs raid5. Anyway I wanted to know if I should replace that drive. I was planning to upgrade my cache soon. smartctl 7.3 2022-02-28 r5338 [x86_64-linux-5.19.17-Unraid] (local build) Copyright (C) 2002-22, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Crucial/Micron RealSSD m4/C400/P400 Device Model: M4-CT256M4SSD2 Serial Number: 0000000013010925333F LU WWN Device Id: 5 00a075 10925333f Firmware Version: 040H User Capacity: 256,060,514,304 bytes [256 GB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Form Factor: 2.5 inches TRIM Command: Available, deterministic Device is: In smartctl database 7.3/5417 ATA Version is: ACS-2, ATA8-ACS T13/1699-D revision 6 SATA Version is: SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Mon Dec 26 16:19:15 2022 CET SMART support is: Available - device has SMART capability.

JorgeB Posted December 27, 2022 Share Posted December 27, 2022 Not a good sign, I would replace it. Quote Link to comment
Solution itimpi Posted December 27, 2022 Solution Share Posted December 27, 2022 5 Reallocated_Sector_Ct PO--CK 100 100 010 - 12288 I am surprised that you have not had issues previously with this drive. A small number of reallocated sectors is normally OK as long as the number remains stable, but a number this large is definitely a sign of trouble. Quote Link to comment
ArdNsc Posted January 16, 2023 Author Share Posted January 16, 2023 Just to let you know in case anyone reads this later: I switched out the faulty drive by now; but I had to use a backup to rebuild the contents of my cache pool -- which is all my fault. I started with a btrfs raid5 (5 drives) and I wanted to remove 2 drives (the faulty one and another small old SSD, only one at a time, of course) and replace it by a newer, bigger one. This is how not to do it: I think I messed things up when I replaced the small healthy drive by the larger SSD (insted of getting rid of the faulty one first). I performed a balance operation (I think it started automatically, the UI does not tell you what Unraid is doing at this point!) and then a scub, which threw a few hundred of errors on me. I performed a second, error correcting scrub operation which left around 100 errors uncorrected. Then I removed the faulty SSD (which just was involved In a full balance operation with lots of data not only read off it, but rewritten to it...), perfomed balance again. I was at my desired config now (4-Drive-Raid5). The next scrub check threw over 9.000.000 errors at me, all uncorrectable. In the logs I found only around 300 faulty files, but even after deleting them, I still got around 5-6million errors. Then I decided that I seriously have fucked things up and started from scratch. Now my new 4-disk-raid5-pool is fine (no more smart errors, no scrub errors) and thanks to full backups I did not suffer any dataloss. (I would not have tried that procedure otherwise.)
