NAME

       s3qlctrl - Control a mounted S3QL file system

SYNOPSIS

       s3qlctrl [options] <action> <mountpoint> ...

       where action may be either of flushcache, upload-meta, cachesize or log-metadata.

DESCRIPTION

       S3QL  is  a  file  system for online data storage. Before using S3QL, make sure to consult the full documentation (rather than just the man
       pages which only briefly document the available userspace commands).

       The s3qlctrl command performs various actions on the S3QL file system mounted in mountpoint.

       s3qlctrl can only be called by the user that mounted  the  file	system	and  (if  the  file  system  was  mounted  with  --allow-other	or
       --allow-root) the root user. This limitation might be removed in the future (see issue 155).

       The following actions may be specified:

       flushcache
	      Uploads all changed file data to the backend.

       upload-meta
	      Upload metadata to the backend. All file system operations will block while a snapshot of the metadata is prepared for upload.

       cachesize
	      Changes  the  cache size of the file system. This action requires an additional argument that specifies the new cache size in kB, so
	      the complete command line is:

	      s3qlctrl [options] cachesize <mountpoint> <new-cache-size>

       log    Change the amount of information that is logged into ~/.s3ql/mount.log file. The complete syntax is:

	      s3qlctrl [options] log <mountpoint> <level> [<module> [<module> ...]]

	      here level is the desired new log level and may be either of debug, info or warn. One or more module may only be specified with  the
	      debug level and allow to restrict the debug output to just the listed modules.

OPTIONS

       The s3qlctrl command also accepts the following options, no matter what specific action is being invoked:

	  --debug
		 activate debugging output

	  --quiet
		 be really quiet

	  --version
		 just print program version and exit

       Hint: run s3qlctrl <action> --help to get help on the additional arguments that the different actions take.

EXIT STATUS

       s3qlctrl returns exit code 0 if the operation succeeded and 1 if some error occurred.

       The   full  S3QL  documentation	should	also  be  installed  somewhere	on  your  system,  common  locations  are  /usr/share/doc/s3ql	or
       /usr/local/doc/s3ql.
