Go to Main - Array Operation and Stop the array.

 

Then get 2 screenshots from Settings and post them, Disk Settings and Global Share Settings.

Done and here they are:

I don't see it on yours either. Not sure how yours got set to no or how to change it to yes except maybe editing the file on flash and rebooting.

It's not showing up because the cache drive won't mount.

That's strange. It was up and running before.

I will try the Single cache drive mode and see what happens for this matter.

Removed the cache drive that didn't mount and running with a single drive cache now.

Copying gets still the same result. No activity on Cache.

Also attaching a new Diagnostics file.

You still have no /mnt/user0 which would be expected if cache were participating in user shares.

 

Try editing config/shares.cfg on flash drive. Change this

shareCacheEnabled="no"

to this

shareCacheEnabled="yes"

You might be able to make this edit from command line or in mc with the server still running and then just stop and start the array to get it to take effect.

Yeah, it's a known bug, for now it needs to be done manually.

Aww, now it worked!

The files are first stored in the cache drive.

Activating Mover will then move the files to HDD array.

Perfect!!

Wonder why this hasn't been taken care of yet.

Should be a simple thing, I guess...

Because it was only found and reported on the latest beta, it should be fixed on the next one.
