Hi all, I urgently need help. After hard power-off (power cable disconnected) my FreeBSD 8.1-STABLE server fails to boot from ZFS with an I/O Error. I was able to boot to Fixit console from 8.2 LiveFS, prepare it for ZFS and mount the pool using "zpool import -Ff" command. Here are the results: Fixit# zpool status =A0 pool: zroot =A0state: FAULTED status: The pool metadata is corrupted and the pool cannot be opened. action: Destroy and re-create the pool from a backup source. =A0=A0 see: http://www.sun.com/msg/ZFS-8000-72 =A0scrub: none requested config: =A0=A0=A0=A0=A0=A0=A0 NAME=A0=A0=A0=A0=A0=A0=A0=A0 STATE=A0=A0 READ WRITE C= KSUM =A0=A0=A0=A0=A0=A0=A0 zroot=A0=A0=A0=A0=A0=A0=A0 FAULTED=A0=A0=A0 0=A0=A0 = =A0 0=A0=A0=A0=A0 1 corrupted data =A0=A0=A0=A0=A0=A0=A0=A0=A0 gpt/array0 ONLINE=A0=A0=A0=A0 0=A0=A0=A0=A0 0= =A0=A0=A0=A0 6 Also "zdb -l /dev/gpt/array0" shows 4 LABELS. Each has the same attributes, in particular: =A0 version=3D14 =A0 state=3D0 =A0 txg=3D4 Here are the screen-shots in case I missed something: https://picasaweb.google.com/113032262178118660549/ZfsFailure# Any pointers how to go about recovering data from this pool anyone? --=20 Piotr Paczynski
