    Kernel crash issue

    So I got my first reboot/crash since I installed kdump. I can see the dmesg log and the dumpfile I don't know how to read the dump itself... I was wondering if someone here could help troubleshoot based on these files content ? /var/crash/202112250917/dmesg.202112250917 in attachment

    Kernel crash issue

    If I may ask, where did you changed the crashkernel to 512M ? Is it like this : /etc/kernel/cmdline: root=ZFS=rpool/ROOT/pve-1 boot=zfs nmi_watchdog=1 crashkernel=384M-:512M EDIT1 : Or should it be like this to fit all ram possibilities ? root=ZFS=rpool/ROOT/pve-1 boot=zfs nmi_watchdog=1...

    Proxmox monitoring / alerting question

    Nah... I don't think so... these are for performance mon aren't they ? Have you ever seen Esx alerts ?

    Proxmox monitoring / alerting question

    Correct. But I really hope we could have a bit more control on the types of alerts, including global system status, temperature, cpus, vm reboots, etc... I'm just surprised that is not implemented out of the box like it is with Esx. Is this something Proxmox is working on ?

    Proxmox monitoring / alerting question

    One of the reason why I still use TrueNas to manage my disks with a passthrough in Proxmox is because if there is a disk failure or anything, I can easily get an alert by email.

    Proxmox random VM / host crash-reboot since migrating to version 7.

    Blacklisting mpt3sas ended up working for me so far since my system didn't crash / reboot for the last 12 hours... Surprising I didn't had to do so with v6. echo 'blacklist mpt3sas' >> /etc/modprobe.d/mpt3sas.conf
