After a recent HDD failure (It was backed up) I purchased a UGreen DXP4800 NAS and set it up.
After a bit of a struggle I managed to mount the NAS on my Home Network using Mountain Duck. I can access and open my photo files from File Explorer (Win 10) but I have tried to create collections from the NAS in digikam but with very limited luck.
The connection to the Maria db works and sometimes digikam will show the collections and then next time when I run it it only shows the ALBUM header.
Digikam + Windows + Mountain Duck + UGreen + Maria db
I think the weak link in this is “Mountain Duck” as a quick look at its web page describes “smart synchronization” .. I believe this to be a can of worms, especially with large data base interactions that depend on accurate timestamps, etc.
