Just fyi for everyone, I've sent a simple patch that I think disables the j= ail checking stuff to Mike and hopefully he can try it. I now see that all the "run nfsd(8) in vnet jails" is not in releng/13.2, but is in stable/13. If it does fix the problem, then I'll have to dig into the ZFS code to try = and figure out how to fix this, yuck! Hopefully Mike can determine if this is the problem, rick > > -GAWollman > >
