Tomcat fails after a reboot

Yesterday our web servers worked fine. We rebooted them last night. Now our apps won't come up. As near as I can tell, the reason is that Tomcat can't see the naming-resource jar.

[tennis@Server bin]$ /usr/bin/tomcat5 run
Using CATALINA_BASE:   /usr/share/tomcat5
Using CATALINA_HOME:   /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp

When I look at /usr/share/tomcat5, I don't see anything out of the ordinary:

[tennis@Server bin]$ ls -las /usr/share/tomcat5/common/lib

Now, I am not the sysadmin nor did I configure this.

I'm not really sure how to proceed now - would anyone have a suggestion?

The problem was that our SAN was corrupted. We had tons of missing JAR and PDF files, as well as some JAR files that were corrupted. Why our (outsourced) data center support staff didn't monitor this and tell us the SAN was coming apart, I do not know. I bet we find out. Oh yes, we will find out.

I also learned our SAN is probably not even RAIDed. /rolleyes

The evil dark side of outsourcing.
