Is it possible to recover a pool (as it was) from a set of disks that were replaced during a capacity upgrade?
wow, that''s a truly excelent question. If you COULD do it, it might work with a simple import but i have no idea...i''d love to know myself.

The transaction numbers would still vary across the drives and the pool information would be inconsistent but I suspect a recent version of ZFS could manage to recover. It might be possible to test this by creating a small, file-backed RAIDZn zpool, simulating a capacity upgrade, exporting that pool and trying to import the original zpool from the detached files. -- Peter Jeremy -------------- next part -------------- A non-text attachment was scrubbed...
