Its a RW-lock though so that read accesses at least can be done across the whole cluster at once. With GFS2 that includes read accesses to rw-mapped mmaped regions of files, for GFS that requires an exclusive lock I'm afraid, Steve. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
