novofine

after not finding any logical explenations for all the issues i decided to do a complete disassembly of the system,clean everything (more or less soaked everything in cleaning alcohol) and rebuild the server again. eversince i had the system running again i had no more errors.

Diagnostics included i know that the behavior i see with the UDMA CRC should or rather cant have nothing to do with Unraid tho this is what i think i am seeing pegasus-diagnostics-20230113-0031.zip

im new to unraid after looking for a replacement of my ageing synology i am running unraid on a Hp DL380e Gen8 the 14 disk variant dual xeon E5-2450L 192gb ddr3 ecc buff/reg HP P420 (non i) 2gb cache with new BBU operating in HBA/ IT mode and the rest of the "default" hardware these units pack i have had the server do a full hardware diagnostic check which it passed without errors it seems to run somewhat unstable and i keep getting read errors and an increasing CRC error count on all connected disks. 3 disks were new/never used rest was was used prior to installing unraid but all had no errors to start with in my search for the problem i have already replaced the storage controller ( P420 in HBA/IT mode) but keep getting the same results, reading many suggestions to replace the sata cables i did the equivalent in the server by replacing the SAS cables with no change in results before i start looking for a new backplane i installed treunas and WS 2019 just to rule out the os being the issue, with the other operating systems i dont see the CRC value increase or notice read errors are there known issues/incompatibility's with running unraid on this kind of hardware and or can it be a setting somewhere in unraid that needs changing? any help is greatly appreciated
