Hi,

i'm trying a ve with <vpsid> putting on a unionfs template_dir:

+ /vz/template/debian-3.1-i386-minimal/ readonly (ro)
+ /vz/private_unionfs/<vpsid>/ read/write (rw)

= /vz/private/<vpsid>/

starting and useing ... all fine, but when i will stop the ve it,
the kernel pull this messages out:

//---

After some testings, it seem the the "umount" process hangs and the ve0 slow down.
After a "timeout"? when the vzdquota process is over -> the ve stoppend and the ve0 works fine!

system: debian-3.1
kernel: (own build) 2.6.16-020test14.4 and unionfs-20060423-1600
with the openvz-patch from http://download.openvz.org/contrib/kernel-patches/unionfs-20 060423-1600-openvz.patch

Any ideas whats going wrong ?

Regards,
Thorsten
