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

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

Advanced options

Mount the filesystem with POSIX ACL support.
Enable localtime log timestamps.
Run in debug mode. This option sets --no-daemon, --log-level to DEBUG, and --log-file to console.
Use 32-bit inodes when mounting to workaround application that doesn't support 64-bit inodes.
Do not purge the cache on file open.
Provide stubs for attributes needed for seamless operation on Macs (the default is off).
Run in the foreground.
File to use as PID file.
Mount the file system in 'read-only' mode.
Enable SELinux label (extended attributes) support on inodes.
File to use as unix-socket.
Key of the volume file to be fetched from the server.
Port number of volfile server.
Transport type to get volume file from server (the default is tcp).
Volume name to be used for MOUNT-POINT (the default is top most volume in VOLUME-FILE).
Mount the filesystem in 'worm' mode.
Add/Override a translator option for a volume with the specified value.
Mount subdirectory instead of the '/' of volume.

Fuse options

Declare supported granularity of file attribute times (default is 0 which kernel handles as unspecified; valid real values are between 1 and 1000000000).
Set attribute timeout to SECONDS for inodes in fuse kernel module (the default is 1).
Set fuse module's background queue length to N (the default is 64).
Set fuse module's congestion threshold to N (the default is 48).
Specify fuse direct I/O strategy (the default is auto).
Dump fuse traffic to PATH
Set entry timeout to SECONDS in fuse kernel module (the default is 1).
Set auxiliary group list timeout to SECONDS for fuse translator (the default is 0).
Enable fuse in-kernel writeback cache.
Set negative timeout to SECONDS in fuse kernel module (the default is 0).
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].
Enable strict volume file checking.

Miscellaneous Options

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

FILES

/var/lib/glusterd/vols/*/*.vol

EXAMPLES

mount a volume named foo on server bar with log level DEBUG on mount point /mnt/foo

# glusterfs --log-level=DEBUG --volfile-id=foo --volfile-server=bar /mnt/foo
