The s3qlctrl command

Synopsis

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

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

Description

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 occured.
