[SOLVED] tmpfs not being used?

tmerriam · 05-13-2012, 03:14 PM

One of my partitons is running out of space, I can't resize it right now, so I'm trying to mount one of the temp file directories on tmpfs.

Code:

/etc/fstab
...
/var/tmp/kdecache-user tmpfs tmpfs nodev,nosuid,size=512M 0 0

Reboot, and...

Code:

mount:
...
/var/tmp/kdecache-user on /tmpfs type tmpfs (rw,nodev,nosuid,size=512M)

Code:

df -h
...
Filesystem             Size Used Avail Mounted on
/var/tmp/kdecache-user 512M    0  512M /tmpfs

ls shows that there are files in /var/tmp/kdecache-user, so why isn't this working?

To mount a directory to RAM should work like you want, but you have mixed up the order of the statements in your fstab, it should be

Code:

tmpfs /var/tmp/kdecache-user tmpfs nodev,nosuid,size=512M 0 0

D'oh!

Ok, I fixed that part but it still doesn't work. I added the uid, gid, and mode options to the fstab entry, and set the permissions on the mount point, but KDE is just making another folder instead! I tried putting the mount point in /mnt and linking to it from /var/tmp, but I have the same issue. Any ideas as to how to trick KDE into using the tmpfs?

I couldn't get just /var/tmp/kdecache into tmpfs, so I mounted on /var/tmp instead. Took off the uid, gid, and mode option from the mount entry, too.
