Hi,

 

Using 4 HDDs in my Helios 4 with Openmediavault 5.5. After a update & restart all the HDD's are gone (not shown at all in lsblk anymore). After poking around in the the systemmessages i found this in dmsg, but don't know what to do with it. 

 

```

Any ideas how to proceed?

It could be caused by power supply failure. Could you check the following thread ?

 

I can't easily check this, what kind of power supply should i buy/try? I'm located in Austria -> Amazon.de

@Yolgie I bought this one: https://www.amazon.de/gp/product/B07Q72NBQK
