undo mkfs

undo mkfs

[Hendrik Levsen]

Hi,

I may have issued an mkfs command onto an already existing, healthy
NILFS volume. This is nothing that can be undone, can it?

Regards

Hendrik

Currently, as I know, there is not utility that can rollback your action. Maybe it is possible to recover this volume by hands on raw sectors basis. But it needs to analyze current state of the volume with care. Anyway, I am afraid that most part of old metadata and maybe user data were corrupted by new metadata structures. 

If you ask about opportunity to undone operation then it means that you haven't backup of the volume. Am I correct?

By the way, did mkfs utility complain about presence of NILFS2 volume on this partition? If not then it can be treated as issue of mkfs tool.

With the best regards,
Vyacheslav Dubeyko.
