Hi all, I have done some tests nowadays. I made a ceph cluster with 1 mon 1 mds and 10 osds. Then I made a block device(use "rbd create/rbd map/.." mount it do a virtual machine as a disk). I stored some data on the disk and broke down the mon. I want to know if there is any way to find out my data with some operations? Can I recreate a mon to take the place of the mon before? Any suggestions are welcome, thank you. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
