Description

Hello

I'm using tmpfs for the /tmp directory on my laptop,
but everytime it boots, it does not mount /tmp.

I added the following line in /etc/fstab

tmpfs   /tmp      tmpfs rw,mode=777,size=1G 0 0

and

tmpfs_load="YES" in /boot/loader.conf

When I want to mount it manually, I get this message:

#mount /tmp
tmpfs: vfsload(tmpfs): File exists

If I kldunload tmpfs && kldload tmpfs, I can mount it correctly !

If I unload the kernel module then I reboot, it'll mount /tmp.

I'm using a custom kernel with SMP support (I only uncommented the
line about SMP) with DragonFly 2.7.3

I'm not familiar with mailing-lists, I hope I'm using it correctly and
I gave you enought informations too.

I'm also about to start a project of auto-benchmarking to find
regressions every day (like phoronix do with Linux),
but I'll tell you more about this if it works !

Hi Charles,

In your custom kernel config file, do you have a line that says?

options TMPFS

If so, you don't need to load the module to have tmpfs working. Make
sure you haven't specified two lines in fstab to mount /tmp.

I've just tested it in my box and it worked fine, it got mounted at boot time.

tmpfs 1.0G 0B 1.0G 0% /tmp2

Also, which DFBSD version are you using?

Cheers,
Antonio Huete

Even if neither module is loaded nor the option is in the config, mount
should load the module automatically.

Thanks you for your replies.

I removed the line "tmpfs_load="YES"" in /boot/loader.conf and it
fixed the problem.
In my kernel config file, the line options TMPFS was there, so I guess
the kernel
has some problem when you try to load a "built-in" module ?

I had only one line for /tmp in my fstab.

The DragonFly version I used was 2.7.3 but now I'm running the
developement version,
I had the bug since the 2.7.3.
