Title: Disk Memory Settings
Post by: Persnickety on April 22, 2026, 09:55:46 AM
My ZFS SSD mirror disks have been beat up by excessive writes from ZenArmor, logs, ntopng, etc etc. I've finally implemented ramdisk, but I'm seeing non-optimal behavior and need some help getting this sorted.

When I do a df -h as root, my /dev/md43 filesystem is only 48M and 103% utilized. When I go to the GUI at System: Settings: Miscellaneous, I have both /var/log RAM usage and /tmp RAM usage set to 25, which the help dialog indicates is a percentage of total RAM. I have 16GB RAM.

Why is /dev/md43 only 48M? I try to adjust the percentage value, but df -h still shows the same 48M.

Any help greatly appreciated. TIA.
