Impact: Fault tolerance of the pool may be compromised. The number of I/O errors associated with a ZFS device exceeded acceptable levels. Here are some of the E-Mails i am getting from the PVE:: I attached the syslogs of the two events as file.ĭoes anybody have an idea what the PVE could be running at friday night at ~02:00 o'clock that causes such failures? I have read that "some ryzen boards may have issues with their SATA onboard controller" - but i replaced the board so that should be fixed if there was an issue with the controller. Replacing the "failed" disk with an 870 EVO 1TB (which just moved the issue to the new disk) Replacing the Motherboard for a new X470D4U (yes, the same board but totally different dealer and production date) Replacing every SATA cable (multiple times) The system gets powered by an APC SMART UPS (load ~25%, one year old). A reboot resolves the issue and a ZFS srub does not find any errors.Ģx Kingston Server Premier DIMM 32GB, DDR4-3200ģx Samsung 860 EVO 1TB (connected via the onboard SATA ports) Last week at ~17:00 o'clock another drive of that pool also switched to "faulted". I am observing some weird behaviour on one of my PVE systems: Every week on firday at around 02:00 o'clock one drive from the ZFS pool switches its state to "faulted".
