Thanks for the help. /etc/passwd and /etc/shadow look ok, running the
tests as a user instead of root does not seem to matter. lc works, ls
-x works, "l" hangs (I let it sit for 5 minutes).
What is really bothering me is that after a hang, I disconnect and
reconnect. My process is still out there (with a parent of 1, the shell
does die). I cannot kill it.
Backups are also getting tape write errors most but not all days. Not
sure if it is related or not. When it does get the error, it occurs
during, not the beginning of the backup. The backup is only backing up
/usr/xxx where xxx has the application and application data in many
subdirectories underneath that tree. I have no problems doing ls -l,
etc on that directory. The problem only seems to be with / and /dev.
What started this was we were trying to mount a cdrom, and it hung.
Booted the machine to a bootable (non UNIX) CD, and it worked fine. So
I went to look at /dev/cd0, and hung doing an ls -l on that....
What is baffling me is why I can do a "file" on some things in /dev,
but not others.
So I'm at a point: hardware or software? If software, what can I do
remotely to fix it - the earliest I can get there to attempt a full
reload is 2 weeks away. Am I sure that a full reload will fix the
issues? And finally, what caused this so we don't end up there
again...
Thanks for the advice so far, and thanks in advance for any help you
can provide in the future.
Kevin
