MC22 for Linux crashing on Raspberry Pi 3

A Pi with 2GB or 4GB would be pretty neat.

Honestly, I wasn't even considering using a Pi for this task.  I was shopping for a Mac mini to do this particular audio "server" duty.  But a friend of mine insisted that I borrow his to test it.  I did, it worked pretty well for a few days, and I bought my own.  The price was very hard to pass up, especially considering that it worked pretty well in my few days of testing.

Frankly, I'm pretty amazed that it works as well as it does.  It's pretty incredible that a "computer" the size of a pack of cigarettes boots "real Linux" in about 20 seconds and runs real deal JRiver Media Center and works mostly just like any other MC computer.  I could see myself with 2 or 3 of these in the future, assuming I can get them totally stable and problem free.

Thanks again,

Brian.

Is that an IdPi or a homebrew build?

I'm using the technique of copying my MC library from my normal MC computer, over to the Pi, on an external hard drive.  I'm also shipping over a library backup file with it, then restoring that library backup into MC on the Pi.  Each time I do this, I guess I need to rebuild all thumbnails.

It's probably NOT a coincidence that I just refreshed the library on the Pi using the above method:  I copied the new media onto the external drive with a backup file, then restored that backup into MC.  I apparently did not rebuild thumbnails when I was doing restoring the MC backup.  This might explain it.

It might also explain why EOS has been very sporadic about showing album thumbnails.  They aren't all built!

I'll report back after some period of stability, or upon first crash.

Thanks Bob!

Library restores do indeed flush the thumbnails everytime; in my experience the best way to use the pi is as a library client of an existing MC instance (preferably on a beefier machine).  Then the thumbnail generation is one and done, and it can mostly run without interference for days or weeks. 

I'd also advise using my systemd service for MC (stickied on this forum) as it will auto-restart MC if it crashes.

It's just a Pi with Raspbian on it.  I considered buying an IdPi, but I was impatient and had already built a proof of concept myself.  I have no doubt that the IdPi is an easier to install solution.

I specifically want a fully stand alone "mini server" for this project.  I'm not a fan of network based sources for home entertainment.  I'm looking for maximum availability and consistency.  In my case I do not have a dedicated MC "master server" that will always be on and not used as a desktop by a human being.  If I had a full powered MC "server" that a human being would never sit in front of, I might revise my opinion.

Hmm, that's new to me.  I'll have to go read the sticky.  Thanks!

Brian.
