New Feature: /tmp and /var RAM disks on Full installs; /tmp and /var resizing
-
Installed the latest snapshot, turned on this feature. Left blank for default space. Installed Squid3 and after reboot it gives me the below error on the login page and I am locked out as I cannot log into the system. The pfSense is a remote box and I don't have physical access to it. Darn !
Warning: session_start(): open(/var/tmp//sess_a5f98c219d39beb8a18480d9a81a2024, O_RDWR) failed: No space left on device (28) in /etc/inc/auth.inc on line 1316

Well what did you expect when you gave it a pittance for space in /tmp and /var and tried to install a package that used it all up?
Unfortunately there is no way to prevent foot-shooting there, but I suppose I could add even more stern warnings to the page.
-
I realized about the setting just the second after I clicked reboot. Any backdoor method to gain access to the system?
-
Hard to say for sure, if you can get it to the console menu at all you might be able to go back to an older version of the config, assuming any are there. It very well could have wiped out quite a bit if /tmp and/or /var filled up.
If you can get to a prompt, check /conf/backup/ and see if there are any old configs there, if there are, then copy one to /conf/config.xml, rm /tmp/config.cache, and reboot

Can't do much remotely. Only access I had to it was over WAN https.

Updated to the latest snapshot via automatic update. No option in System-Advanced-Mics.
What am I doing wrong? -
is it possible to create a option for a third RamDisk?
So we can choose Squid/HAVP/etc for using this space for caching!
so the normal usage of /tmp and /var is not affected?! -

What am I doing wrong?Which option is not there?
On nanobsd, the checkbox "Use memory file system for /tmp and /var" does not appear, because it is not optional - it always "Uses memory file system for /tmp and /var". -

Now it shows
2.1-BETA1 (i386)
built on Wed Apr 3 04:19:20 EDT 2013
FreeBSD 8.3-RELEASE-p7This what I have in System: Advanced: Miscellaneous (see attached image)

You must have some other issue preventing that page from getting updated, but it's not relevant to this thread. Start a fresh thread and someone can help you investigate why a firmware update isn't updating that file.
-
The missing items are all down the end and are all items that have been added in March 2013. My nanobsd system shows them all - Skip rules when gateway is down, /tmp RAM Disk Size, /var RAM Disk Size, Periodic RRD Backup, Periodic DHCP Leases Backup.
It is just as if your /usr/local/www/system_advanced_misc.php was never updated. On your system, check if that file actually contains code for any of these items. Then as JimP recommends, start another thread to try and sort out what happened during updating. -
OK. Now I got this option activated. On reboot I see next (see image)
Any comments?
-
Hard to say exactly. I didn't see that in any of my testing. How large did you try to set the /tmp and /var disks to be? perhaps it used all your memory?
-
2GB of memory installed. 18xxMB free.
First time I have used 512MB for both RAM disks and now I left it blank, when screenshot is taken. -
Clean install from pfSense-LiveCD-2.1-BETA1-i386-20130405-0056.iso.gz
to VirtualBox with minimum config to access web settings and activate RAM disks (all fields are empty only check-box active).
Same error
-
OK that isn't from this code, it's from later in the boot process.
With this option enabled, /var is already a RAM disk. The error comes from mdmfs trying to make a /var/run RAM disk, and failing.

I presume that is on the system. How much RAM have you assigned to the VM running pfSense?

Why are you asking? jimp already found why mdmfs is failing
Anyway it's 4GB of memory in VM -

I can see a report in this topic that mdmfs is failing but I don't see an explanation in this topic of why it is failing so I assumed the issue was still open.
