this error message has nothing to do with the "zfs_arc" plugin, but with
the "interface" plugin. You can resolve it by ignoring the interface
called "mac", that for some reasons is reported multiple times under
certain versions of Solaris. You can do this using the "Interface" and
"IgnoreSelected" options of the "interface" plugin, which are documented
in the collectd.conf(5) manual page.

Do you have a directory named "zfs_arc" somewhere beneath the RRD data
directory? You can use find(1) to look for it, for example:

  $ find /var/lib/collectd/rrd -name zfs_arc -type d
