September 15, 20223 yr One of my disks is constantly going offline, but it's not being reflected in the GUI or logs. The disk will show up fine in the GUI with a green indicator saying the device is active. It's passing SMART, and the disk logs aren't showing any errors. If I launch the CLI type "mc" and navigate to /mnt/ to see disks it shows up red (?diskX) or if I browse the disk via the GUI it says "No listing: Too many files". This has been happening a couple times a day. If I stop and start the array the disk comes back fine again until it eventually just goes back "down". I initially discovered this when sonarr wasn't downloading new episodes one day. I went to investigate and the sonarr logs were filled with array read/write errors. NZBget also has tons of read/write errors. Usually when a disk goes down the data is emulated and still "visible" at least, but this is totally different. The data is gone from the array until I stop and start the array and the disk starts working again. I've tried using a different SAS cable (internal and external) and plugging it into a different port on my HBA card. My disks are in a JBOD.
September 16, 20223 yr Community Expert Disk5 is disabled since you didn't mention that, also read errors on disk7, both look cable related, replace SATA cables, also check filesystem on disk5.
September 16, 20223 yr Author Yeah, I was rebuilding Disk5 when I made the diag file. I've already tried replacing the cable but I'll try replacing it again and update.
September 20, 20223 yr Author Over the weekend I did some testing. Replaced internal SAS cable - same problem Replaced external SAS cable - same problem Plugged into another HBA - same problem Swapped with a hot spare - same problem Currently, it's rebuilding the data on the hot spare and having the issue. GUI is rebuilding the drive fine but the CLI says the drive is offline. coruscant-diagnostics-20220920-1328.zip Edited September 20, 20223 yr by dexdiman Added diagnostic

In what way is it "offline"? That's the problem. The GUI and logs all say the drive is perfectly fine and responding but... If I try to view the contents of the drive via the GUI - I see this: If I try and access the drive via Windows Explorer I can't: Anything on that drive is gone from the array (it's not being emulated or anything). One example is my movies share is missing anything on disk7 when it's down. Number of files when disk7 is working: Number of files when disk7 is down: I don't have any screenshots but sonarr, radarr, and nzbget all show read/write errors and won't function when disk7 goes down. Nextcloud has issues as well. The only way to reliably get disk7 to work after it's gone down is to stop and start the array. Then disk7 comes back and works for an undetermined amount of time before it goes down. An easy and reliable way I can tell if it goes down is by launching the CLI typing mc and navigating to /mnt to see if disk7 is red with a ? in front of it. Even rebuilding the disk causes what I showed in my previous post. The GUI and logs saying disk7 is fine and being rebuild but the CLI showing a red ?disk7 and anything on it not accessible.

I know I've ran that before but it didn't fix the issue so whatever. I'm just glad it's fixed. Thanks.

Yeah maybe. Who knows. I work in IT Infrastructure and see this kind of thing all the time. User tries a bunch of troublshooting - they call me - I try the same things they did and one of them fixes the issue. LOL. Edited September 26, 20223 yr by dexdiman
