Hi, I'm currently putting my first ceph VM cluster into production, it's a cluster where data integrity matters, and I hope ceph won't let me down. Currently I'm trying to figure out how to back up virtual machines. My plan was originally: * Create a snapshot from a VM * Clone that snapshot * map that snapshot * mount that snapshot, let the journaling filesystem replay it's journal * backup that snapshot it turns out that this is a little more complicated than I thought. * cloning is only supported with format=2 * rbd kernel blockdevice is only supported with format=1 so now I'm stuck. I'd also be happy to play around with fuse or something, anybody got any tips? Is format=2 in any respect more 'unstable' than format=1? I do have to decide these days if all the vm's will be running on format=1 or format=2. thanks a lot for you answers Wolfgang -- DI (FH) Wolfgang Hennerbichler Software Development Unit Advanced Computing Technologies RISC Software GmbH A company of the Johannes Kepler University Linz IT-Center Softwarepark 35 4232 Hagenberg Austria Phone: +43 7236 3343 245 Fax: +43 7236 3343 250 wolfgang.hennerbichler@xxxxxxxxxxxxxxxx http://www.risc-software.at _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
