FYI - - The "unrecoverable errors = panic" problem is being fixed as part of PSARC 2007/567.
- We should be able to recover *some* data when some (but not all) toplevel vdevs are faulted. See 6406289. - Reading corrupted blocks is a little trickier, but 6186106 is filed to cover this. That being said, such a tool seems interesting until the above bugs/rfes are fixed. Given that PSARC 2007/567 is undergoing final testing, fixing 6406289 would be a good project for anyone who's interested, as there are some ramifications that make this non-trivial. Fixing 6186106 is much harder, and requires some careful design decisions. - Eric On Mon, Oct 15, 2007 at 12:07:36PM +0200, Mario Goebbels wrote: > > Having my 700Gb one disk ZFS crashing on me created ample need for a > > recovery tool. > > > > So I spent the weekend creating a tool that lets you list directories and > > copy files from any pool on a one disk ZFS filesystem, where for example > > the Solaris kernel keeps panicing. > > > > Is there any interest in it being release to the public? > > Would be nice to have. > > Still, it calls for a recovery mode in ZFS, where all available disks of > the pool are mounted, unrecoverable errors will not cause panics and > missing data is filled with zeroes.
