Hi, You might take a look at http://www.osdevcon.org/2008/files/osdevcon2008-max.pdf and http://www.osdevcon.org/2008/files/osdevcon2008-proceedings.pdf, starting at page 36. Or you might just use od -x file for the file part of your assignment. Have fun. max Eric D.

IMHO the best place to start with this level of analysis is the ZFS on-disk specification doc: http://hub.opensolaris.org/bin/download/Community+Group+zfs/docs/ondiskformat0822.pdf It is getting long in the tooth and doesn't document recent features, but it is fundamentally correct. -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance Las Vegas, April 29-30, 2010 http://nexenta-vegas.eventbrite.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I completely agree with this, but good luck getting a hex dump from that information. max ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
