Since I started using Unraid on Version 6.8.3 I've got a strange issue when copying files directly to the array. CPU load gets to nearly 100% and the UI as well as access to my shares via SMB is extremely slow and buggy. Additionally the access to Web UIs of Docker Containers is not possible. The whole server becomes basically unusable until copying is done. VMs are not affected, though. Checking the top commands shows me a very high wa value with values up to 70-90. After copying has finished, the value drops within a couple of seconds and everything turns back to normal. This is only the case when copying directly to the array without using the cache drive or when Mover is running. I'm currently using the LSI/DELL IT Mode SAS 9207-8i, but the same issue occured with my previous PCIE to SATA controller, as well when the drives were connected directly to the motherboard's SATA connectors. Over the last year I've went through different HDDs and a CPU and mainbaord swap. (From desktop drives to NAS drives and from an Intel i7 4770 to a Ryzen 5 2600 and a Gigabyte B450M D3SH mainbaord.) The issue has been the same througout all the changes. srv-diagnostics-20210526-1044.zip
