chattr breaks web reconfiguration on NFS shares even if protection is disabled
I get the error in /var/log/ispconfig/cron.log
chattr: Unpassender IOCTL (I/O-Control) für das Gerät beim Lesens der Flags in /var/www/clients/client1/web14
Which translates to "Inappropriate ioctl for device While reading flags on". The reason is, that the web root are mounted as NFS share. NFS doesn't support chattr. As I read in http://www.howtoforge.com/forums/archive/index.php/t-64205.html, this security feature seems to be new in ISPConfig 3.0.5.4 I also read, that I can disable this feature in Server -> Web -> Permissions. But this error occures even, if the option is disabled:
[web] security_level=10 set_folder_permissions_on_update=n web_folder_protection=n
What can I do?
