[Cluster-devel] unformat gfs2 - urgent

Tue Mar 18 14:31:20 UTC 2014

I have accidentally reformatted a my GFS2 cluster.
We need to unformat it.. is there any way to recover disk ?

I read this post
http://web.archiveorange.com/archive/v/TUhSn11xEn9QxXBIZ0k6

it say that I can use gfs2_edit to recover data.
I need more details about changing block map to 0xff

tnx
