SYNOPSIS

glusterfs [options] [mountpoint]

DESCRIPTION

GlusterFS is a clustered file system, capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP and interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware, such as x86-64 server with SATA-II RAID and Infiniband HBA.

GlusterFS is fully POSIX compliant file system. On client side, it has dependency on FUSE package, on server side, it works seemlessly on different operating systems. Currently supported on GNU/Linux and Solaris.

OPTIONS

    Basic options

-f, --volfile=VOLUME-FILE
  File to use as VOLUME-FILE.
-l, --log-file=LOGFILE
  File to use for logging (the default is <INSTALL-DIR>/var/log/glusterfs/<MOUNT-POINT>.log).
-L, --log-level=LOGLEVEL
  Logging severity. Valid options are TRACE, DEBUG, INFO, WARNING, ERROR and CRITICAL (the default is INFO).
-s, --volfile-server=SERVER
  Server to get the volume from. This option overrides --volfile option.
--volfile-max-fetch-attempts=MAX-ATTEMPTS
  Maximum number of connect attempts to server. This option should be provided with --volfile-server option (the default is 1).

    Advanced options

--acl Mount the filesystem with POSIX ACL support.
--debug Run in debug mode. This option sets --no-daemon, --log-level to DEBUG, and --log-file to console.
--enable-ino32=BOOL
  Use 32-bit inodes when mounting to workaround application that doesn’t support 64-bit inodes.
--fopen-keep-cache
  Do not purge the cache on file open.
--mac-compat=BOOL
  Provide stubs for attributes needed for seamless operation on Macs (the default is off).
-N, --no-daemon
  Run in the foreground.
-p, --pid-file=PIDFILE
  File to use as PID file.
--read-only
  Mount the file system in ’read-only’ mode.
--selinux
  Enable SELinux label (extended attributes) support on inodes.
-S, --socket-file=SOCKFILE
  File to use as unix-socket.
--volfile-id=KEY
  Key of the volume file to be fetched from the server.
--volfile-server-port=PORT
  Port number of volfile server.
--volfile-server-transport=TRANSPORT
  Transport type to get volume file from server (the default is tcp).
--volume-name=VOLUME-NAME
  Volume name to be used for MOUNT-POINT (the default is top most volume in VOLUME-FILE).
--worm Mount the filesystem in ’worm’ mode.
--xlator-option=VOLUME-NAME.OPTION=VALUE
  Add/Override a translator option for a volume with the specified value.

    Fuse options

--attribute-timeout=SECONDS Set attribute timeout to SECONDS for inodes in fuse kernel module (the default is 1).
--background-qlen=N
  Set fuse module’s background queue length to N (the default is 64).
--congestion-threshold=N
  Set fuse module’s congestion threshold to N (the default is 48).
--direct-io-mode=BOOL
  Enable/Disable the direct-I/O mode in fuse module (the default is enable).
--dump-fuse=PATHR
  Dump fuse traffic to PATH
--entry-timeout=SECONDS
  Set entry timeout to SECONDS in fuse kernel module (the default is 1).
--gid-timeout=SECONDS
  Set auxiliary group list timeout to SECONDS for fuse translator (the default is 0).
--negative-timeout=SECONDS
  Set negative timeout to SECONDS in fuse kernel module (the default is 0).
--volfile-check
