[EMHTTPD: READ SMART KEEPS DISKS SPIN UP]

Swapped from a HP H220 HBA / LSI 9205-8i to Intel RS2WC080 HBA and has been working fine since then

 

Monitoring power usage via an Aqara Zigbee smart plug and Home Assistant

[[unRAID 6.10.0-rc1] - emhttpd: read SMART events keep spinning up array disks]

Was pulling my hair out over this issue, trying everything to isolate what was spinning up array. 
 

Ended up replacing my HBA and it’s been working fine ever since.

 

more info here, hopefully helps

New HBA card arrived and installed, looks like drives are staying spun down,

Glad to finally have this issue sorted!

Believe the “some_random_number.tmp” files are from “CA Fix common problems” 

 

Frustrating thing is same HBA was working fine for spin-down on v6.8…

 

My drives stay spun down for a while but will wake up around every hour, can see clearly via power monitoring

 

Have run all sorts of tests prior to Odering a new HBA, disabled SMB / NFS, new flash drive with clean OS install, disabled VM & docker etc…

Interesting, my current HBA card is an HP H220, maybe it is an issue with HP cards?

I have a new HBA (Intel RS2WC080 - 9240-8i) in the post now will update when it arrives and have swapped it out

I'm having the same issue, on v6.8 spin down was working fine but ever since upgrading I've had an issue,

Drive wake up seams to be every hour, 

 

Noticed quite a few similar bug reports on the forums, most seam to report solving the issue by identifying something accessing the array, however not 100% convinced there isn't a bug.

 

I'm currently debugging on a clean install of 6.10.3 & this is still an issue
