Thread-topic: xfs_repair takes long time
Hello Christoph, 

Thanks, I would try to upgrade it. Could you please tell me whether we can 
recover the data, actually we have all our data about 12 TB resides on that 
volume which has the issue.

Grab the latests version from
git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git, and run it in verbose 
mode (xfs_repair -v).

I suspect you actually have a a volume that doesn't resemble a filesystem 
anymore and it's looking for a superblock but can't find it.
