Hello, For the case of multiple clients(separate process) accessing an object in the cluster, is the exclusive protection of the shared object needed for the caller? Process A::rados::ioctx.write(obj, ...) Process B::rados::ioctx.write(obj, ...) or: Process A:: mylock.lock(); ioctx.write(obj, ..) mylock.unlock() Process B:: mylock.lock(); ioctx.write(obj, ..) mylock.unlock() which one is correct? -- Den _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
