This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Patch(es) available on kernel-2.6.32-238.el6 run autofs connectation and submount test as per comment #9, result passed. autofs connectation: All tests completed Test Summary: parser - PASSED. test1 - PASSED. test2 - PASSED. test3 - PASSED. test4 - PASSED. test5 - PASSED. badnames - PASSED. trailing_space - PASSED. submount-test passed: https://beaker.engineering.redhat.com/jobs/200914 https://beaker.engineering.redhat.com/jobs/200913 https://beaker.engineering.redhat.com/jobs/200910 https://beaker.engineering.redhat.com/jobs/200909 And I will run autofs regression test suite later since some changed against it, I will give comment when I done. autofs regression test results shown as below: autofs regression on old package autofs-5.0.5-39.el6_2.1: https://beaker.engineering.redhat.com/jobs/201338 https://beaker.engineering.redhat.com/jobs/201339 https://beaker.engineering.redhat.com/jobs/201340 https://beaker.engineering.redhat.com/jobs/201341 autofs regression on new package: x86_64: https://beaker.engineering.redhat.com/jobs/212456, For failed bz212249 on client, re-submit https://beaker.engineering.redhat.com/jobs/215181, passed ppc64: https://beaker.engineering.redhat.com/jobs/212455; s390x: https://beaker.engineering.redhat.com/jobs/212247; For failed bz130467 on client caused by no server is on the same subnet as the client. i386: https://beaker.engineering.redhat.com/jobs/215176 For failed bz346091 on server, pls check comment https://bugzilla.redhat.com/show_bug.cgi?id=787595#c21. These rpc null procedure calls for checking server availability added back by developer to check for simple mounts to avoid calling mount.nfs when the server isn't available. And the autofs connectation and submount test results pls refer to comment #18. Patches of comment #6 are applied well. So setting the bug as SanityOnly now.
