[Users] ploop on ext4 without journal - bug?

[Nick Knutov]

Hello all,

I have an ext4 partition without journal (I need it so):

mount | grep vz2
/dev/sde1 on /vz2 type ext4 (rw,relatime,discard,errors=remount-ro,commit=20,data=journal,journal_async_commit)

debugfs -R features /dev/sde1
debugfs 1.41.12 (17-May-2010)
Filesystem features: ext_attr resize_inode dir_index filetype extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize

When I'm trying to create CT with ploop layout - I've got

Creating image: /vz2/private/2008.tmp/root.hdd/root.hdd size=10485760K
Creating delta /vz2/private/2008.tmp/root.hdd/root.hdd bs=2048 size=20971520 sectors v2
Storing /vz2/private/2008.tmp/root.hdd/DiskDescriptor.xml
WARNING: /vz2 is mounted with data=writeback not recommended for ploop; please use data=ordered instead
Opening delta /vz2/private/2008.tmp/root.hdd/root.hdd
Adding delta dev=/dev/ploop58376 img=/vz2/private/2008.tmp/root.hdd/root.hdd (rw)

and now it freezes. (btw, vzctl says it's data=writeback, but it's
data=journal and journal is removed - is it ok?)


When ctrl+c I've got:

^C
Cancelling...
Cancelling...
Destroying container private area: /vz2/private/2008.tmp
^C
Cancelling...
Cancelling...

so I have to log in other ssh session and kill -9 it.

Is it a bug or I'm doing something wrong?
