Hi People, I am testing the new enviroment, with ceph + rbd with ubuntu 16.04, and i have one question.
I have my cluster ceph and mount the using the comands to ceph in my linux enviroment : rbd create veeamrepo --size 20480 rbd --image veeamrepo info modprobe rbd rbd map veeamrepo rbd feature disable veeamrepo exclusive-lock object-map fast-diff deep-flatten mkdir /mnt/veeamrepo mount /dev/rbd0 /mnt/veeamrepo The comands work fine, but i have one problem, in the moment, i can mount the /mnt/veeamrepo in the same time in 2 machines, and this is a bad option for me in the moment, because this could generate one filesystem corrupt. I need only one machine to be allowed to mount and write at a time. Example if machine1 mount the /mnt/veeamrepo and machine2 try mount, one error would be displayed, show message the machine can not mount, because the system already mounted in machine1. Someone, could help-me with this or give some tips, for solution my problem. ? Thanks a lot
