Hi, even if the zfs module is loaded I get the error message: [norman@harmonia ~]$ kldstat | grep zfs 7 1 0xfffffffffcc1c000 80ee8 zfs.ko [norman@harmonia ~]$ zfs list internal error: failed to initialize ZFS library Anyway thx for the info.. At least now I know why it "should" not work ;-) bye Norman 2008/5/29 Pawel Jakub Dawidek <pjd@freebsd.org>: > On Fri, Apr 11, 2008 at 01:41:28PM -0500, Mark Kane wrote: >> On Fri, Apr 11, 2008, at 15:13:16 +0200, Norman Maurer wrote: >> > Hi all, >> > >> > is it normal that I can't do a 'zfs list' ( for example ) as non-root >> > user ? >> > >> > $ zfs list >> > internal error: failed to initialize ZFS library >> > >> > I think there is really a use case for use some zfs commands as >> > non-root user.. >> > >> > Thx >> > Norman >> >> Hi. >> >> One way to do this as a non-root user is to add the account to the >> "operator" group.
