I finally reconverted my only "format 1" image into format 2 so now everything is in format 2, but I'm still confused, my vm disks are still readonly (I've tried different images centos 6.5 with kernel 2.6.32 and ubuntu with 3.13), do I have to modprobe rbd on the host ? De : ceph-users [mailto:ceph-users-bounces at lists.ceph.com] De la part de NEVEU Stephane Envoy? : vendredi 25 juillet 2014 13:45 ? : ceph-users at lists.ceph.com Objet : [ceph-users] RBD import format 1 & 2 Hi all, One quick question about image format 1 & 2 : I've got a img.qcow2 and I want to convert it : The first solution is qemu-img convert -f qcow2 -O rbd img.qcow2 rbd:/mypool/myimage As far as I understood It will converted into format 1 which is the default one so I won't be able to clone my image. Second solution is to import it directly into format 2 : Rbd import -image-format 2 img.qcow2 mypool/myimage But in this case, when I start my VM, my vm / filesystem turns readonly with many buffer IO error on dm-0. I'm running Ubuntu 14.04 for both kvm host and VMs so kernel version is 3.13.0-30 Any idea ? Thx -------------- next part -------------- An HTML attachment was scrubbed...
