[one-users] Problem with raw type on MooseFS and OpenNebula

[Christoph Raible]

HI mailinglist,

I have problems on using OpenNebula with KVM and MooseFS.

In this combination I can't use Images with the RAW filetype.
This is an error/Bug of MooseFS/fuse. Here some quotes from the MooseFS 
malinglist:



###############
MFS is fuse based and fuse does not support O_DIRECT.
You need to add cache=writeback to disk defined in
/etc/qemu-server/$VID.conf
example:

virtio0: MFS_disks:101/vm-101-disk-1.raw,cache=writeback

or

ide0: MFS_disks:101/vm-101-disk-1.raw,cache=writeback
#################



Now is my question how can I add the cache=writeback option to my 
deployment file automaticly? Which file generates the deployment file?

If you need more infos please tell me. Without this "feature" I can't 
use the contextualizing, beacuse the generated ISO file is insert as raw 
type into the deployment file.


Thanks for you Help

Regards,

Christoph
