I use groupquota and userquota in fstab. I tested the patch. With patch there is no crash. But the /etc/rc.d/quota restart leads to the blocking of the file system. You can only turn off the server. This also happens when I only use userquota in the fstab. Sorry, forgot the second diff (now attached) that prevents looping when taking the quota off on a modified file system. Please try again with both diffs applied. > Thank you for your efforts > > Regards > Uwe > > >> >>> >>> Maybe someone can fix the problem. >>> >>> >>> Thank you for your efforts >>> >>> >>> Regards >>> Uwe >> >> -- >> J.
