Oracle Solaris ZFS Administration Guide

ZFS Storage Pool Recovery

Oracle Solaris 10 9/10 Release: A storage pool can become damaged if underlying devices become unavailable, a power failure occurs, or if more than the supported number of devices fail in a redundant ZFS configuration. This release provides new command features for recovering your damaged storage pool. However, using this recovery feature means that the last few transactions that occurred prior to the pool outage might be lost.

Both the zpool clear and zpool import commands support the -F option to possibly recover a damaged pool. In addition, running the zpool status, zpool clear, or zpool import command automatically report a damaged pool and these commands describe how to recover the pool.
