It might be a performance regression, but make sure that your parity is ok: sysctl kern.geom.vinum.debug=4 gvinum checkparity raid5.p0 If you're able to, please apply the following patch in order for the list commands to track your rebuild status with the 'gvinum list -v <plex>' command: http://people.freebsd.org/~lulf/gvinum_setflag.diff Any errors during checkparity should come out in the console. -- Ulf Lilleengen
