NAME

mfshdd.cfg - list of MooseFS storage directories for mfschunkserver

DESCRIPTION

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

SYNTAX

Syntax is:

[*|<|>|~]PATH [SPACE LIMIT]

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.
