NAME

       mount.s3ql - Mount an S3QL file system

SYNOPSIS

       mount.s3ql [options] <storage url> <mount point>

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 mount.s3ql command mounts the S3QL file system stored in storage url in the directory mount point. The storage url depends on the back-
       end that is used. The S3QL User's Guide should be consulted for a description of the available backends.

OPTIONS

       The mount.s3ql command accepts the following options.

	  --log <target>
		 Write	logging  info into this file. File will be rotated when it reaches 1 MB, and at most 5 old log files will be kept. Specify
		 none to disable logging. Default: ~/.s3ql/mount.log

	  --cachedir <path>
		 Store cached data in this directory (default: ~/.s3ql)

	  --authfile <path>
		 Read authentication credentials from this file (default: ~/.s3ql/authinfo2)

	  --debug <module>
		 activate debugging output from <module>. Use all to get debug messages from all modules. This option can  be  specified  multiple
		 times.

	  --quiet
		 be really quiet

	  --ssl  Always  use  SSL connections when connecting to remote servers. For backends that allow only encrypted connections, S3QL uses SSL
		 automatically, even if this option is not set.

	  --version
		 just print program version and exit

	  --cachesize <size>
		 Cache size in kb (default: 102400 (100 MB)). Should be at least 10 times the maximum object size of the filesystem, otherwise	an
		 object may be retrieved and written several times during a single write() or read() operation.

	  --max-cache-entries <num>
		 Maximum number of entries in cache (default: 768).  Each cache entry requires one file descriptor, so if you increase this number
		 you have to make sure that your process file descriptor limit (as set with ulimit -n) is high enough  (at  least  the	number	of
		 cache entries + 100).

	  --min-obj-size <size>
		 Minimum  size	of storage objects in KB. Files smaller than this may be combined into groups that are stored as single objects in
		 the storage backend. Default: 512 KB.

	  --allow-other
		 Normally, only the user who called mount.s3ql can access the mount point. This user then also has full access to it,  independent
		 of  individual  file  permissions.  If  the --allow-other option is specified, other users can access the mount point as well and
		 individual file permissions are taken into account for all users.

	  --allow-root
		 Like --allow-other, but restrict access to the mounting user and the root user.

	  --fg	 Do not daemonize, stay in foreground

	  --single
		 Run in single threaded mode. If you don't understand this, then you don't need it.

	  --upstart
		 Stay in foreground and raise SIGSTOP once mountpoint is up.

	  --profile
		 Create profiling information. If you don't understand this, then you don't need it.

	  --compress <name>
		 Compression algorithm to use when storing new data.  Allowed values: lzma, bzip2, zlib, none.	(default: lzma)

	  --metadata-upload-interval <seconds>
		 Interval in seconds between complete metadata uploads.  Set to 0 to disable. Default: 24h.

	  --threads <no>
		 Number of parallel upload threads to use (default: auto).

	  --nfs  Enable some optimizations for exporting the file system over NFS. (default: False)

EXIT STATUS

       mount.s3ql returns exit code 0 if the operation succeeded and 1 if some error occurred.
