  5. Recommended ZFS pool setup?

  14. [SOLVED] ZFS Dedup: On for Pool, Off for Container Disk?

  15. Proxmox VE 6.0 beta released!

    You can change ARC size live with: #echo 2147483648 > /sys/module/zfs/parameters/zfs_arc_max and #echo 2147483648 > /sys/module/zfs/parameters/zfs_arc_min if you want fixed ARC size. I use /etc/rc.local for custom tuning the startup.
