October 17, 20232 yr I'm not able to disable the ARC for pools/datasets. For example, when I create a dataset with: zfs create -o primarycache=none -o secondarycache=none -o atime=off -o compression=off pool/test doesn't disable ARC caching in my testing. Am I overlooking something or is this expected behavior? Edited October 17, 20232 yr by samsausages
October 17, 20232 yr Community Expert Seems to be working for me, see a very small utilization between 1 and 4% during a transfer but once done it's flushed and goes to and stays at 1%.
October 17, 20232 yr Author @JorgeB I guess I better test it again and monitor my ARC more closely, I didn't check my hit rate. The read test I ran last night was giving me 17,000 MB/s-20,000MB/s, on my VM with a ZVOL and primarycache=none So I figured that performance is coming from the ARC.
