I want to mount a webDAV to a specific disk. I am copying large files to the webDAV, but it appears when I do this, it takes up space on my main disk (which is not /media/username/Crucial) instead of the disk the webdav is mounted on. Can the fstab be setup to have files uploaded/downloaded/viewed (whatever triggers the file to be copied locally) to use the disk it is mounted on.

The relevant lines of my /etc/fstab are below:

/dev/disk/by-uuid/<long-uuid> /media/username/Crucial auto nosuid,nodev,nofail,x-gvfs-show 0 0
https://dav.box.com/dav /media/username/Crucial/box.com davfs rw,user,noauto 0 0

Version info

Ubuntu 22.10

mount.davfs -V
davfs2 1.6.1  <http://savannah.nongnu.org/projects/davfs2>

Disk info

My main drive and secondary drive (Crucial) are ext4.

  • What version of Ubuntu is involved?

the davfs2 configuration might be using a cache directory on your main disk that would cause it to consume space temporarily but with WebDAV the files you upload or download should use the disk space on the mounted disk.

Lets change the cache directory on your secondary drive, first we create the cache directory mkdir /media/username/Crucial/davfs2_cache then we open davfs2 sudo nano /etc/davfs2/davfs2.conf we change the line that start with cache_dir like that cache_dir /media/username/Crucial/davfs2_cache then we save and exit the file and we unmount and mount WebDAV, now it should work

    Thanks for the insight. I searched for the current cache directory and sure enough it was quite large. I'll be sure to implement your solution to put the cache on the desired drive.
