Hi, my system (solaris b77) was physically destroyed and i loosed data saved in a zpool mirror. The only thing left is a dettached vdev from the pool. I''m aware that uberblock is gone and that i can''t import the pool. But i still hope their is a way or a tool (like tct http://www.porcupine.org/forensics/) i can go too recover at least partially some data) thanks in advance for

Hi All, I am looking at trying to understand the conceptual model of how data is grouped and partitioned within a storge pool. In looking at the on disk document that Tabriz sent out a few weeks ago I see that object sets are the grouping which ZFS uses to group objects that are related. Specifially to aid in format and layout of like objects in to a set. So, for example 1 potential object

...tally, leaving either the old version or the new version, but not a combination of the two. This seems sensible to me, but the description of object sets beginning on page 26 of the ZFS On-Disk Specification, states that the DNODE type DMU_OT_DNODE (the type of the DNODE that?s included in the 1KB objset_phys_t structure) will have a data load of an array of DNODES allocated in 128KB blocks, and the picture (Illustration 12 in the spec) shows these blocks as containing 1024 DNODES. Since DNODES are 512 bytes, it would not be possible to fit the 1024 DNODES depicted in the illustration and if DNODES did l...
