Hello!
Unfortunately on one of our Areca RAID controllers has encountered a
power failure which corrupted our zpool and partitions.
We have tried to assemble some new headers but it looks like not only
the headers/uberblocks but also the MOS has been damaged.
We now have moved on from trying to repair the partition to salvage the
non-damaged data of it. I have read all documentation I have found
thoroughly and decided to do the following;
Search for meta-data of files by locating the ZAP object magic-number
(0x2F52AB2AB), from there assemble the meta-data and eventually gather
the data attached. For now I have one question. The zap_phys_t data
structure (described in ZFS On Disk Specifications by SUN), does that
128KB structure reside INSIDE the dn_bonus of the corresponding
dnode_phys_t ? I seem to misunderstand the link between the 2 structures.
Thanks in advance!
Regards,
Gerrit
