Hi Kjo
Do you have any symlinks or special mounts-points for the
directories or files in /var/lib/vz and below?
The strace shows that you probably have a different filesystem
for /var/lib/vz/private compared to the filesystem for
/var/lib/vz/private/101, but I can not tell that for sure.
I still have a really hard time to understand how this can happen based
on the code and the strace. The strace gives me some input and that
is good.
Best regards,
// ola
