Guido, you are absolutely correct. The code for reconstructing/tasting a root pool configuration is a modified upstream code, so it inherited a limitation from it: the support for only a single top-level vdev in a root pool. I have an idea how to add the missing support, but it turned out not to be something that I can hack together in couple of hours. So, instead I wrote the following patch that should fall back to using a root pool configuration from zpool.cache (if it's present there) for a multi-vdev root pool: http://people.freebsd.org/~avg/zfs-spa-multi_vdev_root_fallback.diff The patch also fixes a minor (single-time) memory leak. Guido, Bartosz, could you please test the patch? Apologies for the breakage. -- Andriy GaponReceived on Fri Nov 16 2012 - 14:45:28 UTC
