ChamDwg Posted September 16, 2024 Posted September 16, 2024 Hi All, My system is hanging randomly, It seems I can trigger it faster when I am transferring files via ftp, but it does it other times without warning. When it hangs, the max usage I see is around ~29%, Array is up but none of the apps are accessible and I am unable to collect a diagnostic report when it is in this state. All temps on drives is normal. It will be working, then not working. I have checked the logs unsure of the cause of the dilemma. Server is ~1 month old or so.

Solution JorgeB Posted September 17, 2024 Solution Posted September 17, 2024 Crash is zfs related, so possibly and issue with a zfs filesystem or some hardware issues, like bad RAM, causing it. Quote
ChamDwg Posted September 17, 2024 Author Posted September 17, 2024 Thanks, will take a look and try moving off zfs to see if that helps -- update you in a month when my data moves 😭 it's moving very slow using [unbalanced] Quote
