Hi, I've got FreeBSD 7.2-Stable. I Have 24 drives (/dev/da0- /dev/da23) which I want to add to zfs pool. When I run command # zpool create tank raidz da0 da1 da2 da3 da4 da5 da6 da7 I get an error: Code:cannot create 'tank': invalid argument for this pool operation When I use -n option to create, I get expected result. What am I doing wrong? # zpool create -n tank raidz da0 da1 da2 da3 da4 da5 da6 da7 would create 'tank' with the following layout: Code: tank raidz1 da0 da1 da2 da3 da4 da5 da6 da7 Thanks.
