xfs_rapair memory requirement per TB

[Rene Salmon <salmr0@xxxxxx>]

Hi,

Reading the "Repairing a possibly incomplete xfs_growfs command?" thread
this month makes me wonder if there is some type of rough formula or
guesstimation cheat sheet to figure out how much memory and swap one
would need for an xfs_repair given a file system with many terabytes.


Say I have an 8TB LUN that needs an xfs_repair.  What would be the rough
memory requirements and swap space? 

Thanks
Rene
