pfSense enable RAM Disk issue
-
Hello!
I'm attempting to enable RAM Disk on my PFSense box that I run at home. When I do, the system boots, but is unusable. Looking at the console it complains of /var being full, as seen in the screenshot.
I have attempted both using the minimum values, and 256/256 for both. The system has 8GB of RAM, and plenty of it is unused.
Has anyone ever run in to this? My googling didn't come up with any answers.
I appreciate any guidance that can be provided!
Thank you.

Is this physical or virtual? And 8GB of physical RAM assigned to pfSense?

Its a physical machine. pfsense reports 8029MB, some must be lost for things like the integrated video card.

Well, that should be plenty. Even my VM with 1.5GB total ran RAM disks fine with 120 assigned to /var. It boots normally with /var on hard drive? If so, I'd probably try booting it that way, backing up the config.xml and reinstalling/restoring. Or maybe just boot it normally, reset all the log files, and try RAM disk again. You running pfBlockerNG or Squid? They both cache to /var.

I am using pfBlockerNG. Doing some googling after you asked, it seems like using a ram disk plus pfblockerNG is a bad idea.
I was trying to extend the life of the SSD that I have installed by using a RAM disk. With this new information I may chose to swap it out for a HDD.

Before doing that, see if you can boot normally and set /var to 1GB. You have plenty of RAM. If that works, try reducing to 768, then 512. Maybe works. I had no trouble running PFB on a RAM disk, but every time I rebooted, the /var PFB data got wiped and I either had to wait until the next update or force it. Finally went back to /var on SSD. After all, the whole VM is on SSD anyway...
