December 14, 20169 yr This guide http://www.observium.org/docs/persistent_ramdisk/ (which I will make a modified version of soon) can be used (without some parts) to make a persistent ram disk [glow=red,2,300]***MAKE SURE YOU PUT THE BACKUP ON ONE OF YOUR ARRAY DRIVES !!!NOT!!! ANYWHERE ELSE WHICH INCLUDES THE VAR FOLDER MENTIONED IN THE TUTORIAL***[/glow] I do NOT know if the mounting/creation config file will persist over reboots but the backup folder will stay if you put it on the array
December 14, 20169 yr Community Expert Not sure if I get your meaning, but the /var folder is not on the boot USB, it is in RAM. The only folder on the boot USB is /boot. The disks and user shares are in /mnt. All other OS folders are in RAM. When you boot up, the OS folders are unpacked fresh from bzroot,bzimage into RAM. So, if you write to one of those OS folders, such as /var, then you are writing into a RAM disk of sorts.
December 14, 20169 yr Author sorry about that, I meant to say, don't put ANY files on a tempfs that is not backed up frequently (like every minute), I have experienced the horror of my batch file (in the home directory) disappearing after a reboot!
December 14, 20169 yr Just curious what the use case is for this. With the speeds of modern SSDs, and the typical uses of UnRAID, I don't see any advantage to even bothering with a RAM Disk vs. a high-speed cache drive. Also, your first post says "This guide" => but there's no link to anything -- where is the actual guide?

I have a Command Line plugin that backs up /root on system shutdown then restores it on startup. It's useful for bash history, ssh authorized keys, mc and htop settings and any scripts you have there. It also includes shellinabox, which is a web based terminal. And an awesome ascii lime and system info when you log in.
