I have an unraid installation where after years of running it is now throwing a lot of these udma crc errors. From looking around it seems that the likely culprits are the controller card or the cabling. I am hoping to get some help identifying the issues. I am attaching the diagnostics. Thanks in advance. tower-diagnostics-20240108-2222.zip

Turned out ram I added. After removing them the system is stable.

Have to hard reboot to cycle itower-diagnostics-20231202-1421.zipt up again. Seems stable for 30 mins without mounting the file system and starting the rebuild.

Replaced the motherboard. the onboard SAS seems to have been the failure point

Have removed it completely from the system and plugged the backplane directly into the motherboard instead of the expander card and I still don't have any drive detection. I've tried changing cables as well. seems to be the motherboard HBA/SAS controller at this point to me

After an extended power failure I came home to unraid unable to find any drives. The GUI says they are all missing. I have no idea what to do. Has my backplane failed? tower-diagnostics-20231201-0806.zip

Sadly even adding an ussaigned device to do all the qbit and nzb work and assigning cpus has not seemed to fix it. It is frustrating because I use this same configuration on another unraid server with older hardware with zero issue.

It does not completely crash. It becomes unresponsive for minutes, data transfers halt etc. I need to pin CPUs to counter this from reading that thread?

Hello, My unraid instance is having some very high CPU usage by SHFS that leads to it locking up. I am attaching the diagnostics. tower-diagnostics-20230203-1125.zip
