July 3, 20233 yr Is there a way to set the arc cache size manually? I am running 128gb of ram in my server, with mirrored 1tb cache drives but it seems like the system is limiting the zfs arc cache to 16gb. Thanks. Kartoshka

July 3, 20233 yr Author Solution Thanks a bunch. I created a config file named zfs.conf, added "options zfs zfs_arc_max=64000000000" to the file, saved and uploaded to the modprobe.d file on my flash. Seems to be working. Looking forward to having this in the gui.
