April 11, 20251 yr I have had this system running with some new SAS drives in an external case connected to the SAS controller inside the CPU for a few months now. When I start the external SAS enclosure, the drive doesn't make any sound. When I boot the CPU and it gets to the SAS bios, the drive starts clicking every 5 seconds, and unraid doesn't see the drives. Sometimes, if I wait long enough, the drives in the external array will spin up, and then the SAS bios finds them. Once it's up and running, everything is fine for a few days, and then we get the clicks again. Am I having problems with the external enclosure?

April 11, 20251 yr Author When it's been running for a while, it's just lost the disk, and the web UI is hung. I can get into the console and try a reboot, but that hangs on gathering diag data. I'm assuming that its lost both as SMB and NFS share are also dead

That is true. I have eight spare SAS drives that all click when put in, so I'm thinking it's not the disk. I will double-check the power and cables, but right now, it's running, and I'm doing backups. .

April 14, 20251 yr Community Expert Solution It's not logged as a disk problem, and it's happening to multiple disks, first thing I would try would be to uninstall the SAS spin down plugin to make sure that is not causing issues.

I have unloaded the SAS sleep plugin. Rebuilding parity now. . lets see when they try to go to sleep again if they do
April 17, 20251 yr Author Okay, it's been up for two days now. Not spinning down anymore, but it's stable so far. I'll reach back out in a week if all is good and sooner if not. Thanks all
April 21, 20251 yr Author OK. It's been stable now for almost a week without the SAS spindown plugin... ill post something in the plugin support thread as I would like it to work. Thanks all
