Hello,
Just of curiosity did anybody noticed this interesting stuff?
I got this VM with 16G RAM and 6GB disk.
The disk has only one pool - zroot and looks to me like the ARC cache takes more memory than the pool size is.
And what
Even the only MRU cache is larger than the pool so most used data is more than the pool size and not to talk about that the pool is only 70% full.
Anybody have idea is this a data duplication in the cache or somehow it is expected behavior?
Thank you.
