Between uberblock updates, there may be many write operations to a data file, each requiring a copy on write operation. Some of those operations may reuse blocks that were metadata blocks pointed to by the previous uberblock. In which case the old uberblock points to a metadata tree full of garbage. Jeff, you must have some idea on how to overcome this in your bugfix, would you care to share? --Joe _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
