I have a setup with Raspberry Pi 3, connected to a WD Purple 1 TB internal hard disk, via a hard disk enclosure. The setup is generally stable. I am able to stream videos via DLNA / FTP. I am able to keep the setup running for days together, and all is good.
However, when I have data writes happening, the hard disk automatically gets unmounted. OMV keeps running, so the share is still accessible, but filesystems within that share go missing. The only solution I have, is to login into the portal, and remount the specific hard disk.
I've tried different combinations of the spin down configurations, and they do not seem to help. I know OMV isn't affected, since it keeps running. Only the hard disk gets unmounted, and I am trying to isolate the problem. I think its the hard disk auto spin down, or some problem with the external hard disk enclosure?
Any inputs help.
