I have a DS220+, and both are Western Digital 4TB WD Red Plus NAS drives. My issue is that I ran an extended SMART test on both drives starting at 7 pm last night (3-27), and it is now 10:30 am (3-28) CST. One drive is 40% complete, and the other is 90% complete. Is this normal, or should I be looking at replacing one drive at least?
Synology’s extended SMART test often fails to complete for Western Digital drives. Use the “normal” test. What evidence do you have of drive failure?
The disks are constantly spinning. Based on my research, the VM might be killing them. But, I’m mainly just using the NAS for photo storage, Home Assistant (VM), Adguard (Docker),
Portainer (Docker), Homebridge (Docker), and openspeedtest (Docker). I may be pushing it too hard.
The NAS is intended for 24/7 use. Constantly spinning drives is not an indicator of drive failure.
The test came back as both disks are healthy. I also did data scrubbing, and things seem to. Be better. The only issue I see is that when my Home Assistant runs in VMM, the disks spin like crazy. If I stop the HA VM, the disks stop spinning out of control, and everything seems faster, but I am unsure how to prove that. So, should I move the VM to a Raspberry Pi or maybe use Docker on the NAS to run the VM? I don’t know how to do that.
Yeah, the extended time it took is pretty normal. It goes a lot faster if the NAS isn’t doing anything else (shut down the VM and don’t use the NAS until finished) but obviously takes longer otherwise. The extended test can give you insights into many things the shorter tests do not and it gives a great baseline. Glad they came out OK.
Drive platters spin at a constant rate, or not at all (hibernation/shutdown). Enjoy your NAS.
