NAME

sfschunkserver - start, restart or stop Sauna File System chunkserver process

SYNOPSIS

sfschunkserver [-c CFGFILE] [-u] [-d] [-t LOCKTIMEOUT] [ACTION]

sfschunkserver -v

sfschunkserver -h

DESCRIPTION

sfschunkserver is the data server of Sauna File System. Depending on parameters it can start, restart or stop SaunaFS chunkserver process. Without any options it starts SaunaFS chunkserver, killing previously run process if lock file exists.

SIGHUP (or reload ACTION) forces sfschunkserver to reload all configuration files.

Chunkserver periodically tests stored chunks (see HDD_TEST_FREQ option in sfschunkserver.cfg manual).

SaunaFS master doesn’t send metadata change logs to chunkserver and expect at least one sfsmetalogger daemon to connect.

Chunkserver scans attached disks in background.
