Hey Thanks for the slides but some things are still unclear.
Slide 18 shows variably sizes extents but doesn't explain the process of full-on write. What I'm looking for is one example. I still don't understand how it works with variable sized extents. So if you have 2 stripe units on one disk and 1 stripe unit for the parity and you modify half of the first stripe unit only, when you do a full-stripe write, what happens in terms of a full-stripe write? I also didn't see a distinction between parity and metadata reconstruction. I still do not know the process behind the metadata reconstruction for bad data and when parity is used for bad data. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
