Had a similar problem in the past that turned out to be my fault, wrong
/etc/auto.net script in place. Today, I'm seeing similar mount issue, but
I've made sure the right script is in place.
If a host has >1 export, it works sort of as expected:
kydland mmarion {728}$ /etc/auto.net cornholio
-fstype=nfs,rsize=8192,wsize=8192,hard,intr,acdirmin=1,acdirmax=5,acregmin=1,acregmax=5,nodev,nosuid
\
/local/mnt cornholio:/local/mnt \
/tftpboot cornholio:/tftpboot
kydland mmarion {729}$ ls /net/cornholio
local tftpboot
kydland mmarion {730}$ mount | grep cornholio
cornholio:/local/mnt on /net/cornholio/local/mnt type nfs
(rw,nosuid,nodev,rsize=8192,wsize=8192,hard,intr,acdirmin=1,acdirmax=5,acregmin=1,acregmax=5,addr=129.46.234.38)
but /tftpboot isn't there and debug/verbose output in syslog shows:
Aug 2 13:43:01 kydland automount[32588]: attempting to mount entry

systems
Aug 2 13:43:01 kydland automount[581]: mount(nfs): nfs: mount failure
cornholio:/tftpboot on /net/cornholio/tftpboot
trying to ls that tftpboot path gives more logs:

Even worse, trying to mount a host with a single export mounts at the wrong
place (this is similar to what I saw before):
kydland mmarion {733}$ /etc/auto.net tau
-fstype=nfs,rsize=8192,wsize=8192,hard,intr,acdirmin=1,acdirmax=5,acregmin=1,acregmax=5,nodev,nosuid
\
/local/mnt tau:/local/mnt
kydland mmarion {734}$ ls /net/tau
licenses lost+found mlb usr2 workspace
kydland mmarion {735}$ mount | grep tau
tau:/local/mnt on /net/tau type nfs
(rw,nosuid,nodev,rsize=8192,wsize=8192,hard,intr,acdirmin=1,acdirmax=5,acregmin=1,acregmax=5,addr=129.46.234.39)
It should have mounted as /net/tau/local/mnt not /net/tau
and syslog debug output shows:
Aug 2 13:45:34 kydland automount[32588]: attempting to mount entry /net/tau
Aug 2 13:45:34 kydland automount[977]: mount(nfs): host /local/mnt: lookup
failure
Aug 2 13:45:34 kydland automount[977]: >> nfs server reported tcp not
available, falling back to udp
Host has been up for 61 days, and I could swear it was ok when first booted
(though I could be wrong).
Module loaded is autofs4, not autofs... patched up to 61 days ago.. :)
automount daemon is 4.1.4 with patches from same timeframe.. added patches:
autofs-4.1.4-misc-fixes.patch
autofs-4.1.4-multi-parse-fix.patch
autofs-4.1.4-non-replicated-ping.patch
Seeing same effect on multiple 64bit sles9 hosts, but same level of
daemon/patches and exact same kernel (built from exact same src.rpm anyway) on
a 32bit host (with same /etc/auto.net script) is working fine.
