  1. SLES11 SP3 crashes after integrating into AD

    Hello.
    We're runnning a virtual SLES11 SP3 server on VMware 5. After integrating the Samba into AD (Windows 2008 R2 Std Sp1) the server crashes each sunday at 02:00AM.
    How can I find and fix the error?

    Thanks in advance for tips!

    Best regards

    do you have any details about the "crash" - does the VM hang, is it being restarted,... ?

    Next thing to look at are the system logs (/var/log/messages) and any VMware server logs for the VM.

    As it is reproducible and hits at that exact time, checking cron jobs run at that time might provide a hint, as well.

    There are no cronjobs weekly defined on the server. After looking on my backup software, I disabled the weekly backup of machine using the vmware mechanism instead of saving the files. We're using barracuda backup. So I will wait some days. I hope, that this was the reason for failure. The system freezes completly. It is not possible to logon.

    Moin, moin Dirk,

    the syslog does show that the server is still alive at 2 AM (latest message at 2:00:07)

    > [disabled backup run] So I will wait some days.

    If that back-up run was active around 2 AM, then this sounds pretty reasonable (I take it that you meant backing up VMware snapshots of the VM's disk(s) by your statement "weekly backup of machine using the vmware mechanism"). If that doesn't help, in your position I'd start checking your monitoring tools on when exactly the server went down (i.e. no longer responding to "pings", services not reachable etc) and double-check the VMware logs of the VM for any hints around that time. You could also have a look at the VMware console to correlate disk/CPU activity to the service loss.

    Might it be that your backup is driving the network load too high, creating latencies that lead to a time-out situation when accessing the virtual disk, which is in turn reported to the VM and makes it stall? That's something your network monitoring might reveal and/or lead to messages in the VMware VM log.

    Moin Jens.

    Thanks for your answer. In the notifications I've got from my backup system there is a warning "Changed block tracking is not enabled". I _m not sure, that this is reason for freezing the machine (with ping I'Ve got an answer but no more...) On the vmware server I found a message Errorcode 4: Quiesce aborted.I'll look for that error.

    Best regards.

    Hi Dirk,

    > with ping I'Ve got an answer but no more...

    this may sound like nitpicking, but that VM isn't frozen - at least the kernel and the IP stack are still responsive. Chances are high that some (virtual) disk access problem caused a r/o status of the file system - so no chance to see any output in syslog later on.

    Do you have a chance of leaving open a remote connection to the server, running "dmesg" in a loop (probably starting at about 1:55 AM ) and to set up syslog to send messges to a remote syslog, so you'll have a copy of the messages even after the local FS went unavailable?

    Hi Jens.

    The backup of complete VM was the reason for frozen machine. I disabled the backup las week. This morning it was possible to use server normal. Next I will search for backup error.
    I'll be back when I've got new informations.

    Best regards.

    great, you're on track! And you know how to reproduce the error at some offload time... rather than Monday morning, 2 AM Thanks for reporting back, and let us know if we can assist with further trouble shooting.

    I have a big hunch that it is to do with CPU Frequency Scaling... I have the same problem

    Nov 11 11:01:25 myserver rchal: CPU frequency scaling is not supported by your processor.
    Nov 11 11:01:25 myserver rchal: boot with 'CPUFREQ=no' in to avoid this warning.

    I really don't see how this has anything to do with the original, 4 year
    old thread?! Also, why do you think it's a problem? That message is
    completely normal in a virtual environment, and causes no problems.
