Linux (XenServer) Input/Output Error

Greetings,

I was happily coding along yesterday when my virtualized web server stopped responding to requests.  I SSHed into the host and got the following error:

 bash: /sbin/reboot: Input/output error

I had to restart using

echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger

Once the server restarted, the system seemed to work OK.  But what's going on?  Is there a hard drive failure imminent?  How can I tell?

It's certainly not a good sign that your system is unable to load /sbin/reboot from the HDD...it could certainly be indicative of a pending disk failure.

Check it out with fsck: http://adminschoice.com/repairing-unix-file-system-fsck

/var/log/messages was untelling...

Do you have any other ideas where I might find some clues?

No. I'd look in allt the logs that's available. If I didn't find anything there I wouldn't have a clue.

Try a grep "|error" /var/log/* > errors.log

Then vi /var/log/errors.log
