https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251395 Bug ID: 251395 Summary: rc.d/nfsclient: hangs at shutdown because of non-empty /var/db/mounttab Product: Base System Version: 12.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: d8zNeCFG@aon.at Scenario: - multiple machines using NFS and autofs (automount) - some of them running FreeBSD 12.2, the others 12.1 - at the end of the day they are shut down simultaneously; before that, it is ensured that all NFS mounts are unmounted (using automount -u and checking via "df -t nfs") Result: - The 12.2 machine hangs in the rc.d/nfsclient script with repeated error messages indicating it cannot contact the remote portmapper: the remote portmapper does not reply anymore because that machine is also going down. - This happens because the file /var/db/mounttab is non-empty and still indicates the remote NFS servers despite the fact that all NFS mounts have already been unmounted. Expected result: - After the last NFS mount from a server has been unmounted, the corresponding entry in /var/db/mounttab, and the complete file if empty, should be removed. - This should enable rc.d/nfsclient to skip any further NFS server notification during shutdown. -- Martin -- You are receiving this mail because: You are the assignee for the bug.home | help
