noatime on UFS on new installations, what about ZFS file system?



  • I figured out how to edit etc/fstab using VI and add noatime to existing pfSense installations as I upgrade them to 2.4.5, but, I have started using ZFS on a lot of new installations.

    Is there an equivalent for ZFS installations or does the standard ZFS file system install already have atime=off (which seems to be the ZFS equiavlent)?

    Thanks!

    It seems to be off by default. This is on a fresh installation of 2.4.5 with the default pool name zroot:

    [2.4.5-RELEASE][root@..]/root: zfs get atime zroot
    NAME   PROPERTY  VALUE  SOURCE
    zroot  atime     off    local

  • I'm pleased to see atime is off already on a 2.4.4 ZFS file system install.

    Yah!

    [2.4.4-RELEASE][admin@...]/root: zfs get atime zroot
    NAME   PROPERTY  VALUE  SOURCE
    zroot  atime     off    local
