ZFS Boot problem after hard shutdown while resilvering RAIDZ1

[Alexey Tarasov]

Hello.

I have the same problem. You can do three things: 1) do nothing and wait, because ZFS pool starts resilvering 2) set LD_LIBRARY_PATH to /zroot and use all utilites 3) Exit from fixit after import and enter it again. ZFS will be mounted and shell will be functional.
