Yes and no. The mv-process is still running, however I can use 'zroot'  
without issues. I can list some folders on 'storage', but not all --  
most of them makes my terminal freeze. And as mentioned, a warm reboot  
doesn't work (I have to physically power-cycle it).

No, not in my last error-log (only boot-entries on the lines above).

This won't "conflict" with what you've written here[1]? The 9211-8i  
controller I have, use the SAS2008-chip.

Would it be possible that low amounts of free memory (<100MB, the  
system has a total of 4GB) could cause this? (since I'm using ZFS,  
which relies heavily on memory).
