system hangs at Mount file systems .......

ran_li — Tue, 06 Sep 2005 14:29:09 GMT

Hello all, need a clue to troubleshoot system hangs at start up time. I m able to enter single user mode, ran the fsck then either go to runlevel 2 or reboot the system, it will hangs at Mount file systems .... stage, please give a direction. Thanks.

Check if you have any NFS mounts made from the fstab and if yes check if the nfs server(s) is/are alive for these mount points. It does not seem like you have any corrupt local volumes so, this leaves some external (NFS/CDFS/etc.) filesystems to blame.

Re: system hangs at Mount file systems .......

Paul Sperry — Tue, 06 Sep 2005 14:37:20 GMT

I think Mel is correct. It's probably an old/missing nfs mount. Check your /etc/fstab
and comment them out (you can allways mount them later)

Re: system hangs at Mount file systems .......

Hi guys, thanks for the thoughts but it does not have any nfs mount

# cat /etc/fstab
# System /etc/fstab file. Static information about the file systems
# See fstab(4) and sam(1M) for further details on configuring devices.
/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /home1 vxfs delaylog 0 2
/dev/vg00/lvol5 /opt vxfs delaylog 0 2
/dev/vg00/lvol6 /tmp vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2

nor does it a NIS client.

I can mount all of the volumes manually in single user mode, how come it will stack during the boot.

Have you made any changes to /etc/fstab recently? Try to recreate the fstab manually and see if that helps.

ran_li — Tue, 06 Sep 2005 15:12:55 GMT

No, the /etc/fstab was not touched by anybody, plus it's identical to other boxes which can be booted up. any other suggestions?

Re: system hangs at Mount file systems .......

Mel Burslan — Tue, 06 Sep 2005 15:13:28 GMT

a suggestion:

can you try booting to single user and mount the filesystems one-by-one manually to see what the heck is going on. With the barebones filesystem structure, I do not see any reason why it should hang like that.

Re: system hangs at Mount file systems .......

ran_li — Tue, 06 Sep 2005 15:36:12 GMT

when I entered single user mode

# mount
/ on /dev/vg00/lvol3 log on Tue Sep 6 16:24:05 2005
/stand on /dev/vg00/lvol1 defaults on Tue Sep 6 16:24:06 2005

after mounting everything manually

# mount
/ on /dev/vg00/lvol3 log on Tue Sep 6 16:24:05 2005
/stand on /dev/vg00/lvol1 defaults on Tue Sep 6 16:24:06 2005
/home1 on /dev/vg00/lvol4 log,nodatainlog on Tue Sep 6 16:25:25 2005
/opt on /dev/vg00/lvol5 log,nodatainlog on Tue Sep 6 16:25:53 2005
/tmp on /dev/vg00/lvol6 log,nodatainlog on Tue Sep 6 16:26:09 2005
/usr on /dev/vg00/lvol7 log,nodatainlog on Tue Sep 6 16:26:27 2005
/var on /dev/vg00/lvol8 log,nodatainlog on Tue Sep 6 16:27:02 2005

no error was reported.

after init 2 or reboot, it will hang at "Mount file systems ... " like before.

I think it appears stopping at "Mount file system ... " but have other reasons, not only fstab, sorry I don't have a clue.

Hi,

/sbin/init.d/localmount script is used for mounting file systems while OS is booting. What happens if you try to mount file systems using this script inspite of mounting manually.

Try in single user mode and observer the output.

#sh -x /sbin/init.d/localmount

HTH,
Devender

Re: system hangs at Mount file systems .......

Mel Burslan — Tue, 06 Sep 2005 15:51:52 GMT

Ran,

Under the circumstances, you have a little investigation to do. edit the file:

/sbin/init.d/localmount

and just before the first uncommented line, insert another line like this

set -x

save it and reboot your machine. when it attempts to mount all filesystems, server will execute this command and will give you an output of every command it executes or tries to execute in this little script. It will most probably mess up your screen but you can live with this just this once. Watch the screen (capture it if possible using a terminal emulator and its logging capabilities) very closely as the commands execute and see where the execution stops and waits. You may be running into a misconfigured quota situation. If you can get any reasonable screen capture, feel free to post them here for further help.

Hi Mel, Devender and all,

I always appreciate you guys' help, just don't know this rule here, I will append the points for all my post, the link you give it to me does not work in my browser, I will find all my posts. Thanks for the reminder.

the scripts stopps at quotacheck

# /sbin/sh -x /sbin/init.d/localmount start
+ PATH=/sbin:/usr/sbin:/usr/bin
+ export PATH
+ rval=0
+ /sbin/mountall -l -m
+ set_return
+ [ -f /quotas -a -x /usr/sbin/quotaon ]
+ [ -x /usr/sbin/quotacheck ]
+ echo checking quotas
checking quotas
+ awk
$1 !~ /^#/ { if ($3)
if ($3 != "swap" && $3 != "noswap" && $3 != "ignore")
types[$3] += 1
}
END { for (i in types)
printf ("%s ", i);
printf ("\n");
} /etc/fstab
+ quotacheck -F hfs -a -P

then hangs here.

Regards!

Ran,

If your system is version 11i, I do not see a -P option for quotacheck command on the manpages for the command.

Unless you are using and enforcing quotas, try commenting the quotacheck command lines in the localmount script and try rebooting hopefully one final time.

When youare all done, if you modified this script localmount as I suggested above, you may want to remove those set -x statements before completing your work.

Re: system hangs at Mount file systems .......

ran_li — Tue, 06 Sep 2005 16:56:08 GMT

Thanks Mel, I can go to runlevel 2 and 3 now, I commented out following lines,

# hfs) quotacheck -F $i -a -P # preen quota stats
# set_return
# ;;

Just curious, how come I have other 11i boxes which with exactly the same lines in the /sbin/init.d/localmount do not have this kind of problem at all, besides, this host was working properly before, this just happened all of sudden.

I also tried remove the -P option but it does not work,

hfs) quotacheck -F $i -a # preen quota stats
set_return
;;

everything is the same like before (hangs at Mount file systems ...), unless I comment out all above 3 lines.

Regards!

it is a wild idea but either you are missing a patch to fix quotacheck command on this server or someone migh have brought the quotacheck command from another server, which may be incompatible. Check the filesize of the command between this server and a server you know it is working (make sure this server is running the quotacheck command in its localmount script first)
