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.
