Hi, We added max and min settings in zfs.conf and changes was apply. We set min 115 and max 130. After that I saw that Cache hit ratio: 95% and Cache miss ratio:4%
When we used default 2 TB for max , I saw that hit: 99,8% and miss: 0,2%.
How to calculate values that hit ratio will be 99%?
Thanks
we have default values c_min 135 G and c_max 2TB. I want change this. We paste max = 37Gb, but this value did not apply because current value min value more than my (135GB > 37GB) . If I'll write max and min together in zfs.conf, system apply these parametrs. Do I think right?
If I have 4 TB...
now I see my value "37580963840"

Ok, if you said that "min" value, we not necessary to use because Proxmox6 used ZFS 2.0.x , why our steps was failed, when we try to accept settings, we wrote only max value? Thanks
We tried to use changes with only "options zfs zfs_arc_max" parameter on small test vm and we saw changes without "options zfs zfs_arc_min"
Does we need necessary to use "options zfs zfs_arc_min" if I want to use options zfs zfs_arc_max?
Hi, We need some help.
We have server with:
