mfshdd.cfg - list of MooseFS storage directories for mfschunkserver


The file mfshdd.cfg contains list of directories (mountpoints) used for MooseFS storage.


Syntax is:


Lines starting with # character are ignored as comments.

Path can be prefixed with one or more special characters. These characters work as additional options.

means this directory (hard drive) is "marked for removal" and all data will be replicated to other hard drives, usually on other chunkservers
means that all data from this hard drive should be moved to other local hard drives
means that all data from other local hard drives should be moved to this hard drive
means that significant (more than 10% in less than minute) change of total blocks count will not mark this drive as damaged (useful for compressed filesystems)

PATH is path to the mounting point of storage directory, usually a single hard drive.

SPACE LIMIT is optional space limit, that allows to set one of two values: how much space should be left unused on this device or how much space is to be used on this device. Definition format: [0-9]*(.[0-9]*)?([kMGTPE]|[KMGTPE]i)?B?, positive value means how much space to use, negative value means how much space should be left unused.
