running xfs_repair on large partitions

[Louis-David Mitterrand <vindex+lists-xfs@xxxxxxxxxxx>]

Hello,

1) it would be nice to have a way to know xfs_repair's version (-V ?), 
when using it from a rescue disk I'm never sure if I should get a newer 
one.

2) on a 32bit system, using xfsprogs version 2.9.0 , it seems xfs_repair 
will fail if its process exceeds 4G. Is that right? Is there a way to 
circumvent that limitation?

Thanks,
