ZFS scrub will detect many types of error in your data or the filesystem metadata.
If you have sufficient redundancy in your pool and the errors were not due to dropped or misordered writes, then they can often be automatically corrected during the scrub. If ZFS detects an error from which it cannot automatically recover, it will often instantly lock your entire pool to prevent any read or write access, informing you only that you must destroy it and "restore from backups" to get your data back. Your only recourse in such situations is to do exactly that, or enlist the help of Victor Latushkin to attempt to recover your pool using painstaking manual manipulation. Recent putbacks seem to indicate that future releases will provide a mechanism to allow mere mortals to recover from some of the errors caused by dropped writes. cheers, Rob -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
