[I warn that I'm a fairly minimal user of NFS mounts, not knowing all that much. I'm mostly reporting this in case it ends up as evidence via eventually matching up with others observing possibly related oddities.] I got the following odd sequence (that I've mixed notes into). It involved a diff -r over NFS showing differences (files missing) and then a later diff finding matches for the same files, no file system changes made on either machine. I'm unable to reproduce the oddity on demand. Note: A larger scope diff -r originally returned the below as well, but doing the narrower diff -r did repeat the result and that is what I show. (I make no use of devel/ice .) # diff -r /usr/ports/devel/ice/files /mnt/devel/ice/files | more Only in /usr/ports/devel/ice/files: Make.rules.FreeBSD Only in /usr/ports/devel/ice/files: patch-config-Make.common.rules Only in /usr/ports/devel/ice/files: patch-cpp-Makefile Only in /usr/ports/devel/ice/files: patch-cpp-allTests.py Only in /usr/ports/devel/ice/files: patch-cpp-config-Make.rules Only in /usr/ports/devel/ice/files: = patch-cpp-include-Ice-FactoryTableInit.h Only in /usr/ports/devel/ice/files: patch-cpp-include-IceUtil-Config.h Only in /usr/ports/devel/ice/files: = patch-cpp-include-IceUtil-ScannerConfig.h Only in /usr/ports/devel/ice/files: = patch-cpp-src-Glacier2CryptPermissionsVerifier-CryptPermissionsVerifierI.c= pp Only in /usr/ports/devel/ice/files: patch-cpp-src-Ice-ProxyFactory.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-src-IceGrid-PluginFacadeI.cpp Only in /usr/ports/devel/ice/files: patch-cpp-src-IceGrid-RegistryI.cpp Only in /usr/ports/devel/ice/files: patch-cpp-src-IceSSL-Makefile Only in /usr/ports/devel/ice/files: = patch-cpp-test-Glacier2-ssl-Server.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-test-Glacier2-staticFiltering-run.py Only in /usr/ports/devel/ice/files: patch-cpp-test-Ice-info-AllTests.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-test-Ice-metrics-AllTests.cpp Only in /usr/ports/devel/ice/files: patch-cpp-test-Ice-objects-Makefile Only in /usr/ports/devel/ice/files: patch-cpp-test-Ice-properties-run.py Only in /usr/ports/devel/ice/files: patch-cpp-test-IceGrid-admin-run.py Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-deployer-AllTests.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-deployer-Makefile Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-deployer-application.xml Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-distribution-AllTests.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-distribution-application.xml Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-distribution-run.py Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceGrid-session-run.py Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceSSL-configuration-AllTests.cpp Only in /usr/ports/devel/ice/files: = patch-cpp-test-IceSSL-configuration-run.py Only in /usr/ports/devel/ice/files: patch-cpp-test-Slice-headers-run.py Only in /usr/ports/devel/ice/files: = patch-cpp-test-Slice-unicodePaths-run.py Only in /usr/ports/devel/ice/files: patch-cpp-test-include-TestCommon.h Only in /usr/ports/devel/ice/files: patch-php-Makefile Only in /usr/ports/devel/ice/files: patch-php-config-Make.rules.php Only in /usr/ports/devel/ice/files: patch-php-lib-Makefile Only in /usr/ports/devel/ice/files: patch-python-Makefile Only in /usr/ports/devel/ice/files: patch-python-config-Make.rules Only in /usr/ports/devel/ice/files: patch-python-modules-IcePy-Types.cpp Only in /usr/ports/devel/ice/files: patch-python-modules-IcePy-Types.h Only in /usr/ports/devel/ice/files: patch-python-python-Makefile Only in /usr/ports/devel/ice/files: = patch-python-test-Ice-info-AllTests.py Only in /usr/ports/devel/ice/files: = patch-python-test-Ice-properties-run.py Only in /usr/ports/devel/ice/files: = patch-python-test-Slice-unicodePaths-run.py Only in /usr/ports/devel/ice/files: patch-scripts-Expect.py Only in /usr/ports/devel/ice/files: patch-scripts-IceGridAdmin.py Only in /usr/ports/devel/ice/files: patch-scripts-TestUtil.py Note: The above was not expected.
