system hangs at "mount file systems......"

[heath seals_1]

greetings-

i have two hpux 9000/800 ( one 11.00 and one 11i ) systems that are hanging during system start-up at "mount file systems.......". i can boot into single user mode and mount all the filesystems with no problem. any clue as to why it might be hanging during a system boot?

thanks and take care.

Two quickies to look at.

look at /etc/fstab

Are you doing any nfs mounts? If so, are the machines up.

nfs core won't come up if there are typos in /etc/rc.config.d/netconf

check that for typos, and possbily restore it.

look back at /etc/fstab for erorrs there.

Check for NFS Mounts in /etc/fstab,...

Also, can you resolve your hostname using 'nslookup [hostname]'?

Share and Enjoy! Ian

Heath,

First, have they ever worked properly or is this a new install? Maybe something along the lines of hostname resolution could be holding things up.

Hi,
i think you have some NFS mount in you fstab and it's not able to reach your NFS server.
just # NFS entries and try to boot.

i should have included this in my original message, but there are no NFS mounts on this box. they are all local filesytems.

also, this is not a new install. they were both rebooted in early may and came up fine.

thanks for your continued help!

Look in /etc/rc.log (and /etc/rc.log.old) and check for messages from this script below:

Mount file systems
Output from "/sbin/rc1.d/S100localmount start":
----------------------------
checking quotas

Mounting of file systems is done by:

/sbin/init.d/localmount

which is called in the boot sequence by the script above (it's a link).

It checks quotas. Are your quotas set up correctly?

It checks /etc/fstab.

Put a set -x in the localmount script, reboot and see what happens. Point log at a file. Put these lines in boot script:

LOG=/mount.log
exec 2>${LOG}
exec >&2

Never leave any scratch files in /etc/rc.config.d/. They get executed.
Check for files there since last boot.

Check for any new files or changes in the boot sequence files, like /etc/inittab (run level), /sbin/init.d/, /sbin/rcX.d/, etc. Did you install any new products? like Legato Networker. That messes (incorrectly) with boot start.

Heath,

OK, so they used to work but now they don't. The obvious question is what changed in the meantime. Any hostname alterations, ip-address changes, DNS issues?

greetings!

after adding "set -x" to the localmount script, i got some useful output. localmount hangs while checking quotas. although quotas are not enabled on this box, i use ldap for centralized authentication so ldap is listed in nsswitch.conf. i removed ldap from nsswitch and it boots fine. im hoping i can configure nsswitch.conf to ignore ldap if its unavailable. im thinking this will solve my problem.

any thoughts?

Heath,

Sorry, unfamiliar with ldap but glad you found the problem.
