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.
