[rhn-users] How to find out what caused server crash

[Doerbeck, Christoph]

Also curious as to your hardware... please post general
summary, or if willing .... output from `dmidecode`.  Be aware
that serial-number data may be captured & reported by dmidecode.

Can you post 
 - your /etc/fstab, 
 - output of 'df -h', 
 - output of 'mount | grep opt', and
 - your /proc/partitions file?

Sounds like maybe the filesystem is mounted read-only or it is full...

Also, try tailing /var/log/messages while you touch a file in that
directory and googling any error messages that you get as a result of
that touch.  If you can't get anywhere with those errors, post them to
the group as well.

Hello,

I need help troubleshooting RHE3 Server.
This computer has been rebuild recently and is currently running
2.4.21-27.0.4.ELsmp. Last weekend it stopped responding and I can not
find the reason for the failure. We had to reboot the server to regain
the access to it. This server is used for web application deployed on
tomcat. The application is using Lucene for documents search, and the
document indexing threat was running when the crash occurred. The server
had a problem again during the week. I was told that after login-in
using ssh user got an error about non existing link in /opt directory,
something about inode being invalid. The mentioned link has never been
created on this machine. 
Also on Wednesday when I tried to replace a file in the application
after running cp command I got a message that file I am trying to create
doesn?t exist. I ?touch file_name? to create the file in that directory,
and again I got a message that file I am creating doesn?t exist. (same
when I tried to create this file using vim) I had to delete that
directory and move new copy of the directory together with the file. (I
have tried both the owner of the directory and root account; the
permissions can not be a
problem)

I am not sure how to deal with this. Would this be a
problem with the faulty installation or a hardware failure?
How can I find out what has caused the crash? Or how should
I proceed to troubleshoot this?

Thank you in advance,
DarekC
