I'm new to unraid (on 6.9.2) and have been having a great time, running the usual Plex setup, with it until I took a look at my disk stats the other day which shows: Naturally this has scared me a bit so went to investigate and saw regular 700+ MB/s reads/writes on my cache. By running iotop -oa I could see the process that was using the disk IO which turns out to be about 8 processes hammering the SSD named: /usr/local/sbin/shfs /mnt/user -disks 3 -o noatime,allow_other -o remember=0 Any ideas what is causing this and how I can fix it? Thanks!
