System hang at ... checking for disk quotas.

[Jacqueline Nguyen]

Hi Everyone, Please help.
Where can I find tips, docs, solution or anything that help me to understand the following situation:

My system is HP9000 K-360, HP-UX 10.20. We also have finance applications in Universe Basic, version 9.4.1.1I. On Friday one of my users logs into the Accounting system. While entering his login name and password the system hang at Please wait ...checking for disk quotas sentence. I checked the syslog.log and did not see any abnormal errors on the connection. Please advise. Thank you all for your help.

Do you have any NFS mounted file systems on this box? If something was NFS mounted from another machine, and the NFS server had a problem that caused the mount point to be unavailable then you could see something like that.

Another potential cause is if you have any file systems unavailable because of disk failure, or something like that. But then you should see some messages in syslog.

Was it just one particular user that had problems or all users?

Until Patrick's questions are answered you can get around this (temporary fix by disable the quota check) by ...

# chmod 000 /usr/sbin/edquota
# chmod 000 /usr/bin/quota

At least your users can login and do his/her work ..

[Roger Baptiste]

This happens if there are
NFS filesystem errors.

If you do not use quotas(allocation limited space for
users), you can jump the problem by:

mv /usr/bin/quota /usr/bin/quota.orig
cp -p /usr/bin/true /usr/bin/quota

That should zip through the
quota checking process ;-)

Hi,

IS it that only one of your user is unable to login or all of your users are unable to login. If it happens for only one user, it could be a user related problem, sya profile or something like that. If it happens for all, it could be a system wide problem.

Hope this helps.

Patrick,
Thanks for a quick response. Here are the answers for your questions:
1. My user logs into the mail server then telnetd to the HP9000.
2. I did an ioscan -fC disk and all devices are claimed.
3. Only 2 users had that problem. After couple tries, one was able to get through.

Is there other files that I need to check on my system. Thank you for your advise.

[G. Vrijhoeven]

Hi,

I like to add one.

1. Does the .profile of the user that can not log in differ.

2. How many telnetd are allowed check the kernel parameter 'nstrtel' it specifies the number of telnet device files.

3. cat /etc/fstab it should show a quota setting on the HOME file system if it is turned on.

Hope this will help.

I had the same problem, but for everyone on the system. Maybe the problem is similar. For what it's worth, here it is.....

We have two HP V-class computers, A and B. Both are wired up to the same 8 disks. Computer A has the disks mounted. Computer B knows they are there via ioscan. But computer B does not have them in any volume group.
Now computer B nfs mounts these disks from computer A. Then both A and B hang.

Cause? The scsi id controller is set to 7 for BOTH computers. Computer B sees the disks via the nfs mount (scsi id 7), and sees the disks via ioscan (scsi id.....7). OOPS!
Solution: Computer B's scsi id to access these disks should be set to a unique number (in this case 6).

Thank you all for your responses. Here are some additional info of my system:
.I have only one HP K-class box. No NFS mounted
.Simple profile: export term type and path working directory.

Gideon,
1. What is the command or how can I find out the # of telnetd from the Kernel parameters. What is 'netrtel'.
2. This is my /etc/fstab. Where the quota # locates:
...
/dev/vg01/lvol6 /disk1 vxfs rw,suid, delaylog, detainlog 0 2
...

I appreciate all your help and advices. Thanks a lot.

Hi Jacqueline,

Try this link below for "nstrtel".

http://docs.hp.com//hpux/onlinedocs/os/11i/kcparams/KCparam.NstrTel.html

To find out the present kernel setting for this parameter, try this,

kmtune -S /stand/system |grep nstrtel

this may return the vaule in numerical or formula mode. If in formula mode, grep for the other variables. On my system it return the vaule of MAXUSERS, the maxusers variable on my system is set to 200.

hope this helps.

Hi Jacqueline,

Here is a link to the description of "maxusers" in case you are interested,

http://docs.hp.com//hpux/onlinedocs/os/11i/kcparams/KCparam.MaxUsers.html

also about your probelm. you can try one more thing, if the NIS client is enabled on your system, disable it and see if it helps. I think that would be,

/sbin/init.d/nis.client stop

Hope this helps.
