Answer 1

You shouldn't delete any files from directories (typically HDDs mountpoints), which are listed in /etc/mfs/mfshdd.cfg, because the files which are inside directories presented by you on the screenshot above (chunks, named as you mention chunk_xxx.mfs) contain your data!

If you want MooseFS to move chunks from specific HDD to any other HDDs, just put an asterisk (*) before the path to this HDD in /etc/mfs/mfshdd.cfg - it will move chunks to other HDDs, typically on other Chunkservers. If you want to move chunks to other HDDs on the same machine, put "lower than" sign (<) before the path to specific HDD in /etc/mfs/mfshdd.cfg, e.g.:

*/data/mfs

or:

</data/mfs

For more information, refer to man mfshdd.cfg and read the comments in /etc/mfs/mfshdd.cfg.dist (MooseFS 2.0) or /etc/mfs/mfshdd.cfg.sample (MooseFS 3.0).
