What would be the correct way to convert the xml file rbdmapped images to librbd? I had this: <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/rbd/rbd/vps-test2'/> <target dev='sda' bus='scsi'/> <boot order='1'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> And for librbd this: <disk type='network' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <auth username='rbd.vps'> <secret type='ceph' uuid='79834913-05cf-47b6-8e77-9a139d0f10ef'/> </auth> <source protocol='rbd' name='rbd/vps-test2'> <host name='192.168.10.111' port='6789'/> <host name='192.168.10.112' port='6789'/> <host name='192.168.10.113' port='6789'/> </source> <target dev='sda' bus='scsi'/> <boot order='1'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> But this will give me a qemu format drive option: -drive file=rbd:rbd/vps-test2:id=rbd.vps:key=XXXXXWHYISTHISEVENHERE????==:auth_ supported=cephx\;none:mon_host=192.168.10.111\:6789\;192.168.10.112\:678 9\;192.168.10.113\:6789,format=raw,if=none,id=drive-scsi0-0-0-0,cache=wr iteback And not format rbd: -drive format=rbd,file=rbd:data/squeeze,cache=writeback As specified here, http://docs.ceph.com/docs/luminous/rbd/qemu-rbd/ If I change type='raw' to type='rbd', I get error: unsupported configuration: unknown driver format value 'rbd' Linux c01 3.10.0-693.5.2.el7.x86_64 #1 SMP Fri Oct 20 20:32:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linu ceph-mgr-12.2.1-0.el7.x86_64 ceph-12.2.1-0.el7.x86_64 libcephfs2-12.2.1-0.el7.x86_64 python-cephfs-12.2.1-0.el7.x86_64 ceph-common-12.2.1-0.el7.x86_64 ceph-selinux-12.2.1-0.el7.x86_64 ceph-mon-12.2.1-0.el7.x86_64 ceph-mds-12.2.1-0.el7.x86_64 collectd-ceph-5.7.1-2.el7.x86_64 ceph-base-12.2.1-0.el7.x86_64 ceph-osd-12.2.1-0.el7.x86_64 ceph-deploy-1.5.39-0.noarch _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
