HA - Crash report - Need help to understand why



  • Hello,

    I would like to know if you can analyse the crash report and help us to understand why the slave pfsense was crashed and why we had a downtime on our first pfsense and instability during 30 minutes period.

    I explain, we have two pfsense configured in HA in the version 2.1.5 (I know this is an old version, we have a project to upgrade). Last week, we have a downtime of our production and so, our internet lines were down (fiber, VPN, VDSL) : the first pfsense had high load average : ~ 13 and the secondary pfsense was crashed with this crash report. We have shutdown the secondary and disable the SYNC (HA - pfsync) interface to bring back to the life the first pfsense.

    Actually, these PFSENSE are virtualized with Proxmox and Intel e1000 network cards  (we would like to upgrade in physical with the newest version but I have tested it and we have a problem with IPSEC and FTP).

    So, can you help us ? Do you need more informations ?

    Thanks.

    Your disk and/or disk controller is shot.

    A wipe and reload might help but it looks more like hardware to me because of the NMI trap there – that signal can only be generated from hardware.

    If it was just a corrupted filesystem it would only have crashed in filesystem functions and it wouldn't have the NMI bits in the trace.

  • Sorry i don't really understand your answer (and English isn't my native language). Is there a problem with the hard drive ? I must check it ?

    A problem with the hard drive or possibly the disk controller itself on the motherboard (where the drive is plugged in)

    I'm not sure if proxmox is smart enough to generate an NMI on its own for things like that, so it may be passed through from the actual hardware.

    There is a chance it's something in proxmox or the host itself, but someone more familiar with proxmox would have to chime in and answer that part.
