[CentOS] XFS-in-a-file

Hello listmates,

Has anybody attempted to run an XFS in a file mounted via -o loop? The file
size is about 20 TB and it resides in a larger XFS filesystem residing on a
disk. That filesystem's size is about 25 TB. What sort of degradation
should one expect under that sort of scenario?

The reason I am asking is that I am trying to run a MooseFS chunkserver in
that filesystem-in-a-file and looks like I am getting some pretty bad
delays.

Thanks.

Boris.
