Hi all,
Just completed my first unRAID build. I'm running 6.6.7 and have four 8TB HDDs in my array, a single 10TB HDD for parity and a 512GB SSD for cache. Is it normal for this much disk usage (see below) without having written anything to the array yet? I should note that I'm about 50% through initial parity sync and not sure if that factors into the mix with any temp data in play.

I'm especially curious about the cache drive. Why is there a 20GB docker image?
root@kunnandi:/mnt/cache# du -h
