GlusterFS(8)

NAME
GlusterFS - clustered file system

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.

--localtime-logging
    Enable localtime log timestamps.

--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[=BOOL]
    Do not purge the cache on file open (default: false).

--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.

--subdir-mount=SUBDIR-MOUNT-PATH
    Mount subdirectory instead of the '/' of volume.

  Fuse options

--attr-times-granularity=NANOSECONDS
    Declare supported granularity of file attribute times (default is 0 which kernel handles as unspecified; valid real values are between 1 and 1000000000).

--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|auto
    Specify fuse direct I/O strategy (the default is auto).

--dump-fuse=PATH
    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).

--kernel-writeback-cache=BOOL
    Enable fuse in-kernel writeback cache.

--negative-timeout=SECONDS
    Set negative timeout to SECONDS in fuse kernel module (the default is 0).

--auto-invalidation=BOOL
    controls whether fuse-kernel can auto-invalidate attribute, dentry and page-cache. Disable this only if same files/directories are not accessed across two different mounts concurrently [default: on].

--volfile-check
    Enable strict volume file checking.

  Miscellaneous Options

-?, --help
    Display this help.

--usage
    Display a short usage message.

-V, --version
    Print the program version.
