Hi there,
I am running my server on an really old i5-6600 with one parity drive and a couple of data drives.
I have a docker container setup to automatically back up the content of my array (via /mnt/user ) to a cloud provider. Now I am not sure how their software scans files/disks, but every time this container runs, shfs pins a core to 100%(which is fine), but it is also causing a lot of iowait shown in above picture. I am wondering if there is a way to mitigate this issue.
After some research I conducted a while ago (so its all kind of fuzzy for me right now), I believe I read somewhere that directly reading a drive (as in via /mnt/disk1, /mnt/disk2) could potentially lower the shfs overhead. Is this true? What other ways can I lower the iowait/shfs overhead?
I have moved my appdata and docker.img to cache so those are not contributing factors to the iowait anymore.
Thanks!
