This might be a whole thing, but I have been dealing with quite a few CRC errors on my disks. I have changed the cables power supply and even the case to do away with the back plane and connected my SAS to SATA card directly to the drives. Recently I have been rearranging my shares which means I have been moving a lot of data within the array. Several times during this process the webgui becomes unresponsive and slowly over the course of several hours I start losing docker containers and the ability to connect using SSH. Before I lose the ability to connect via SSH, powerdown doesn’t work and downloading the diagnostics just hangs up. Eventually I must force an ungraceful shutdown. Fortunately, or unfortunately, this hasn’t happened since I started keeping persistent logs. So I don’t have any from when that happened and I am not sure if this is related to the disk issues or not. I have noticed several disk errors on one particular drive located at ata14.00. Last night that drive disconnected from the array and I was only able to get unraid to recognize it again once I unplugged it and plugged it back in so it could have been a loose connection. During this time I rearranged several of the sata connectors and I am still getting the same errors this time on ata15.00 so I assume it is drive related. My array consists of mostly WD red 4 and 8 tb drives but the vast majority of errors are isolated to three 8tb white label EDAZ drives that I shucked from easystore or element enclosures. Its hard for me to imagine that all 3 of these drives are bad but that seems to be the common dominator so any input would be appreciated. I have attached the server logs that I have as well as the SMART data from the 3 drives. Any input would be appreciated. Thanks,
