Ubuntu Manpage: mount.s3ql - Mount an S3QL file system

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 backend 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 MiB,
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 KiB (default: 102400 (100 MiB)). 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).

--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.
