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 KiB, 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.
