I have gotten a report from others experiencing this as well. 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:

Any errors during checkparity should come out in the console.
