actually i realy feel stupid :

this is a known issue on owncloud 7
http://doc.owncloud.org/server/7.0/user_manual/files/files.html#known-issues
it might have been fixed on owncloud 8

i just didn't felt concerned because i had not this sepcific "Resource temporarily unavailable" error

i join the debug trace for information.

anyway thanks a lot for the help

This looks like a bug in how owncloud handles LOCK requests.

I would strongly suggest to track down the reason for this problem to be able to fix it instead of doing a lot of blind trial and error and searching the internet for people that seem to have the same problem.
If it turns out to be a bug in davfs2, I will fix it. If it is a bug in owncloud, a detailed bug report will help the owncloud developers to fix it.

davfs2 has an easy to use and powerfull feature for this: debug messages.

Please do this:

  • temporarily remove option 'use_locks 0'
  • add option 'debug most'
  • mount your file system
  • copy just one small file into your davfs2 file system, for instance "echo test > <moutpoint>/test"
  • wait about 15 seconds
  • unmount the file system
  • search your system's log files for entries from mount.davfs
  • send the debug messages
  • don't forget to remove option 'debug most'


There is a real good chance that the debug message will show exactly what is going wrong. If not they will at least hint at where to look next.

i finally found this thread :
http://forum.owncloud.org/viewtopic.php?f=29&t=22613
seems to have more to do with an owncloud bug, then !
- sorry to bother

use_locks 0 is an acceptable solution to me

hello

i just mounted my owncloud dav (remote debian) on two differents computers running latest linux mint. i ran into the same issue on both :
i can create directories but everytime i try to create a file in davfs mounted directories i get an "invalid argument" error e.g. :

krodelabestiole@linux-mint ~ $ cp /home/krodelabestiole/activity.sh /mnt/davfs/owncloud/activity.sh
cp: impossible de créer le fichier standard «/mnt/davfs/owncloud/activity.sh»: Argument invalide

you can translate by :
cp: cannot create regular file «whatever file»: Invalid argument

it doesn't work also to create file with any text editor or such.

i can get and modify existing files. i can create directories.

i tried absolutely any option i could in fstab (rw,user,auto,_netdev,uid=krodelabestiole,gid=krodelabestiole,file_mode=755,dir_mode=755) or no options at all and i have not touched to davfs2.conf (everything is commented). i tried to mount and create files as root or as simple user using fstab automount or "mount -t davfs" - i tried absolutely every options i had in mind and way to mount this - except modifying davfs2.conf

i found only this two other occurences of what seems to be the same problem :
https://www.centos.org/forums/viewtopic.php?t=18641#p88548
http://www.unix.com/emergency-unix-and-linux-support/235563-adding-permanent-mount-davfs2-2.html


help on this issue would be greatly appreciated !
thank you
