[MB] Unfortunately we do not have any recommendations for the filesystem on chunkservers. Generally speaking every filesystem is good. Some differences just appear in very big production environments. We use ext3 and are quite satisfied. We wait for your observations :) Kind regards Michal > On the MooseFS side there are really some deletion limits which depend on > the number of chunks necessary to delete.

As a workaround, instead of copying the files we symlink the origin directory and 'tar czhf' it. Regards, -- Ricardo J.
