Hello
I have a strange thing going on with my DS920+ and new DSM 7.0 and its SSD caching. Im using 2x 500 GB Samsung 970 EVO which are on compatibility list for DS920+.
I ve done an upgrade from DSM 6 to DSM 7 months ago but few days ago I noticed that my SSD Cache is telling me that its not in a newest version. So I google and the problem is, that DSM 7 can utilise SSD Cache in better way with some applications and use metadata for Hyper backup and ABB.
So I deleted my SSD Cache and set a new one.
After this setup I noticed that HDDs are constatly awake, doing noises like constantly witing small amout of data every few seconds. And this is a screen of running proceses.
I know that it should be writeback from SSD to Volume but its doing all the day except some hours and even when there is no work on NAS for a long time.
I tried to check and uncheck the Metadata usage and still the same thing happens.
I heard from Synology technician, that if you use only read cache its working, but why you shoudl do that if you have two SSDs installed.
Also removing the Cache solves this problem.
Has anyone experinced smth similar?
Thanks
