December 20, 20232 yr So i recently upgraded my backplane to SAS3 as my previous one had failed. I also upgraded to an LSI SAS 9300-8I for controller card. Since i am doing all this work i have disabled parity and just trying to organize some things. For some reason if i try to read from a hard disk in the array using krusader i could only get like 2MB/s MAX. When i read from SSD or NVME and write to a disk in krusader, it works great and with no parity i am getting well over 150MB/s writing to the hard disks. I have installed the diskspeed docker, and tried benchmarking drives, and all the HD's are basically at 2MB/s (images attached) Any idea what could be going on? I also attached diagnostic. tvserver01-diagnostics-20231220-1126.zip
