Update: I tried turning all sharing off and shutting down the one PC I had used to access, and they drives did sleep. I will gradually turn things back on and see what is causing it.
So I have a my cloud mirror gen 2. I have upgraded to OS5. I have noticed since the upgrade that the drives never sleep, at all. The unit is pulling 15watts 24/7 and the drives are constantly spinning. I have turned off cloud access and ssh and the problem persists.
Sometimes I might not access the device for a few days, seems pointless to have the drives spinning and wasting all that power and heat constantly. I have the “Drive Sleep” option turned on.
The only way I have got the drives to sleep is by unplugging the network cable and then leaving it for 20 minutes.
I have seen other posts where drives are intermittently waking, but with mine it is just constant, never spin down.
Any ideas for things I can try?
Ok, next update. So it seems to be having an SMB mapped share. I am guessing even though I am writing nothing to the drives, I am guess windows is doing some kind of check to see if the mapped drive is still up and that is taking the drives out of sleep.
I will see if it is repeatedly reproducible and report back.
Others have had this problem.
Not sure I ever heard the cause.
One theory related to things like PLEX.
Another theory centered on the Cloud Access.
NOTE: If you turn off cloud access; then the unit will do a complete re-indexing if you ever enable it again. Indexing is a serious brush with death for any MyCloud Mirror.
Thanks for the reply. Ok, so having turned off Cloud Access, and making sure no other access is going on the drives are now finally sleeping. I will try turning back on Cloud Access in a day or so and see what happens. It is only pulling 5 watts now with the drives in a sleep state. Cloud access would of course be good but not if pulling 20 watts and having the drives going 24/7. Although I don’t really want to spend the money, I would be tempted to swap out the two drives for two SSDs.
