November 2, 20223 yr New build, Ryzen 5 2400G CPU, 8GB RAM, GigE NIC, 3 x 4TB Ironwolf drives and 1 x Samsung SSD 256GB Cache drive. Running trial of 6.11.1. Did the initial format and parity check last night. Came up clean. Temps around 32C the whole time. All good. Created a few shares and copied about 10GB of data to the cache as a test. Initiated a 'move' from the UI and lost access to the webgui. Thought maybe it was just temporary IO load. After a few minutes realized something was wrong. Turned on the console screen and could see a stack trace from a kernel fault. What would have caused that? What should I do?
November 2, 20223 yr Author I guess I need to get used to a full parity check being required on each power loss/crash event. Hopefully they are infrequent, of course. Will the data that was in the process of being moved when the kernel crashed still be on the cache drive or is that a situation where something could have been corrupted in process?
November 2, 20223 yr Author Am discussing in the Discord with someone as well. Currently running a Memtest (had to make sure I booted in CSM compatibility mode, not UEFI, for Memtest to load) Have replaced the cable completely to that drive. If Memtest is clean, will try another port on the board. There are two available ports on an ASMedia chip, whereas the three HDD and SSD are currentnly on the SATA ports directly off the CPU. Was hoping to avoid having to transit to the other bus.
November 3, 20223 yr Author Solution I've made the change to the Idle Power option in the BIOS (can't recall the setting, basically don't have it reduce at all) and I've turned off any suggestion of overclocking in the bios (the AUTO settings) per the Unraid FAQ in the post above this one. I also changed all the SATA cables and I made sure I have no drive on a shared SATA port that is shared automatically with an unused M2 slot. One of these changes appears to have resolved the issue as I am almost all the way through a rebuild of the drive and I haven't had a single CRC error. Edited November 3, 20223 yr by Alex43
