Hi, I'm implementing a file system FSAL which is similar to CEPH FSAL. I checked ceph_fsal_lock_op2() and other FSAL lock_op2 implementation. The owner parameter is a pointer, but it converts it to 64bit integer and sends to CEPH. Ceph will judge if it's a conflict according to this value. My question is : 1. it's possible that different clients have the same value even though the possibility is very low. 2. When this sever reboot and reclaim the lock, this value should change. Thanks, Marvin
