Hey everyone,

I am loving snakeoil. I want to see if I can have a persistent RAM disk for my favourite tracks, so I don't have to manually add the files each time I start up the server.

I've read a webpage that you can do it with ramdisk-sync? https://linuxhint.com/ramdisk_ubuntu_1804/

Thoughts? The instructions are for ubuntu 18 and our snakeoil is on ubuntu 16.

The RamDisk itself is "persistent" in SnakeOil in that it is set up during boot. Rather than do a backup of the RamDisk and reinstall, an easier way is to set up a playlist to load music to RamDisk after boot.

Hey @Snoopy8 ! Smile

I wasn't aware playlists can do the copying too?

I have setup playlists to play from the nvme.

RAM by default isn't persistent. Content will be lost when PC is rebooted, or shutdown.

Having said that, I am not sure if Intel Opane will work - it's marketed as persistent memory. I believe there are some servers with battery backed RAM also.

There's nothing Snakeoil OS can do, it's hardware.

Thanks @agent_kith. I tried copying the music files using playlist. Found some weird results. Using ramfs, it results in errors saying no files copied. with tmpfs, it copies the m3u playlist and not the music files.

@Snoopy8 , when you say load the music files after boot using playlist, you're referring to the manual process via the web interface browser? It can't be automated upon boot yeah?

Your playlist is bigger than the RAM disk you allocated. Snakeoil does not check if there's enough space for you to copy the files or not. With one of the file systems (Can't remember which), it never checks for disk full and will have weird results.

So to use this feature, make sure you allocate enough size for your RAM disk..

This was a suggestion from me in the RamDisk thread. I am hoping that Agent Kith can create a script to read a "RamDisk auto load" playlist after the system comes up.

Upgrading SnakeOil from 16.04 to 18.04 is easy. But the sound is not as good as 16.04 in my system. And the upgrade is not reversible unless you go for total re-installation.
But if running SnakeOil OS as music server only, 18.04 produces much better sound than 16.04. Of course I have no idea why.

Hi @agent_kith , i created a ram disk of 4GB. I couldn't copy via the M3U playlist for even 5 songs in a playlist. ? Ramfs says error files not copied and tmpfs copies the m3u playlist file itself

Hmm. Weird, this sounds like a bug.. I'll hopefully give it a go later today and see if I can re-create this. Will let you know. It's already a busy day at work so ping me again if you havn't hear from me in a few days (just in case I forget).
