[Users] Problem checkpointing VE with AUFS root

[Josiney de Souza]

Hi,

Recently, I started to use OpenVZ. My goal is run some VE's with a remote
root, mounted with AUFS and each branch of AUFS is a NFS from a server.

My problem is: I can't checkpoint a VE with AUFS root. Every time that I try
it, I receive the follow output:

---
root at vcg:~# 
root at vcg:~# vzctl chkpnt 104 dumpfile dump.104
Setting up checkpoint...
        suspend...
        dump...
Can not dump container: Invalid argument
Error: pg->mapping!=f_mapping: 08048000 c0c37b60 dfaa9e84 43824
Error: dump_one_vma: funkey page
Checkpointing failed
root at vcg:~# 
---

My system is Debian Lenny and vzctl package version is 3.0.23-1dso1.
I build my kernel from 2.6.27 sources, following steps in AUFS page and
applying the kernel patch 2.6.27-briullov.1-combined .

Checkpointing from a local filesystem root (ReiserFS) or NFS filesystem root
works, but not from AUFS root.

Anyone has a hint what is wrong?
