What you are doing *will* lead to file corruption. Your need to use a distributed filesystem such as GFS2 or cephfs. CephFS would be probably be the easiest to setup. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
