https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246750 Bug ID: 246750 Summary: ZFS: Confusing error message when creating ZFS pool on vdev Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: kwiat3k@panic.pl On default FreeBSD configuration (vfs.zfs.vol.recursive =3D=3D 0) it's impo= ssible to create ZFS pools on vdevs. When users try to do this they see generic and confusing error message: ``` # zfs create -V 1G -s zroot/kwiat # zpool create -f kwiat /dev/zvol/zroot/kwiat cannot create 'kwiat': no such pool or dataset ``` For someone not experienced in ZFS it will take some time to learn how to workaround this as it seems it's not documented anywhere. What's more, on L= inux it just works. My ideas how to improve this: 1) Better error message when vfs.zfs.vol.recursive=3D=3D0 and backing devic= e is zvol. Example: "cannot create 'kwiat': creating pool on zvol is dangerous. See man zpool(8) for more info." 2) Document it in the zpool(8) manpage in "zpool create" section --=20 You are receiving this mail because: You are the assignee for the bug.=
