Description xiaoli feng 2016-11-17 11:06:08 UTC

Description of problem:
Test autofs hosts map, happen this error:

ls: cannot access /net/hp-dl380pgen8-02-vm-7.lab.bos.redhat.com/tmp: No such file or directory

The debug log:

Nov 17 05:35:33 hp-dl380pgen8-02-vm-7 automount[13638]: state.c:627: assertion failed: ap->state == ST_READY || ap->state == ST_EXPIRE
Nov 17 05:35:33 hp-dl380pgen8-02-vm-7 automount[13638]: nextstate:85: write failed Bad file descriptor
Nov 17 05:35:33 hp-dl380pgen8-02-vm-7 automount[13638]: state.c:627: assertion failed: ap->state == ST_READY || ap->state == ST_EXPIRE
Nov 17 05:35:33 hp-dl380pgen8-02-vm-7 automount[13638]: nextstate:85: write failed Bad file descriptor
Nov 17 05:36:48 hp-dl380pgen8-02-vm-7 rpc.mountd[13565]: Caught signal 15, un-registering and exiting.

Version-Release number of selected component (if applicable):
2.6.32-671.el6.x86_64

How reproducible:
100%, but only first time boot from installing system can reproduce.

Steps to Reproduce:
1. reproducer script:
echo "/ *(rw,insecure,async)" >/etc/exports
echo "/tmp *(rw,insecure,async)" >> /etc/exports
echo "/net  -hosts" > /etc/auto.master
service   autofs start
service nfs start
ls /net/$HOSTNAME/tmp
service autofs stop
service nfs stop


Actual results:

auto mount nfs fail

Expected results:

auto mount nfs successfully

Sorry, Version-Release number of selected component is
autofs-5.0.5-126.el6

Comment 2 Ian Kent 2016-11-17 11:23:56 UTC

I'll try and reproduce this and see if I can see what's going on.

But rpc.mountd getting a SIGTERM and exiting, likely in middle
of servicing a request from automount(8) is a bit suspicious.

This looks like it is being done on the same host.
Is that correct?

Can you re-run this test and post the autofs debug log please?

Yes, on the same host. This test only use one host.
