GlusterFS - clustered file system

glusterfs [options] [mountpoint]

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.

-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).

--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.

--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=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).
--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.

-?, --help
Display this help.
--usage
Display a short usage message.
-V, --version
Print the program version.
