Hi, I installed Debian 4.0 + ISPConfig through the perfect setup. It has crashed about 3 times in the past 24 hours and I don't have a clue how and why. The complete system freezes and the only way to recover is to turn the server off and on again, then it will boot fine. When it freezes the harddisk LED is on everytime. I really want to solve this but what am I looking for? What logs to check? What things to test? I installed the SMP kernel and it ran stable for about 2 weeks, all of a sudden it keeps crashing every now and then. The only thing changed is the CPU fan of 1 of the CPUs, it runs fine and keeps the CPU cool enough (can touch the copper parts of the cooler and they are just warm, not hot. Please help me out.
Can you see anything in the /var/log/messages or dmesg? You could also try to get some hints running a smartctl check on your harddisk (cause you said the light was lightning, when the PC crashed) or your could start via a rescue cd (e.g. debian netinstaller or knoppix) and do a fscheck.
in /var/log/messages the last few lines before the crash: Code: Jul 10 22:23:40 server -- MARK -- Jul 10 22:43:40 server -- MARK -- Jul 10 23:03:40 server -- MARK -- Jul 10 23:23:41 server -- MARK -- Jul 10 23:43:41 server -- MARK -- in /var/log/dmesg nothing special to see... What excactly is smartctl and how do I run it? Never ran into these kind of problems before so no experience with it
You have to install it (in case you have not done yet): aptitude instal smartmontools then run e.g. smartctl -a smartctl --test=long /dev/hda etc.
Ok so I installed it and enabled S.M.A.R.T. on this drive, it says: Code: === START OF ENABLE/DISABLE COMMANDS SECTION === SMART Enabled. SMART support is: Available - device has SMART capability.
