GlusterFS \- clustered file system
16
.I [options] [mountpoint]
19
GlusterFS is a clustered file system, capable of scaling to several peta-bytes.
20
It aggregates various storage bricks over Infiniband RDMA or TCP/IP and
21
interconnect into one large parallel network file system. Storage bricks can
22
be made of any commodity hardware, such as x86-64 server with SATA-II RAID and
25
GlusterFS is fully POSIX compliant file system. On client side, it has dependency
26
on FUSE package, on server side, it works seemlessly on different operating systems.
27
Currently supported on GNU/Linux and Solaris.
34
\fB\-f, \fB\-\-volfile=VOLUME-FILE\fR
35
File to use as VOLUME-FILE.
37
\fB\-l, \fB\-\-log\-file=LOGFILE\fR

41
Logging severity. Valid options are TRACE, DEBUG, INFO, WARNING, ERROR and CRITICAL (the default is INFO).
43
\fB\-s, \fB\-\-volfile\-server=SERVER\fR

47
Maximum number of connect attempts to server. This option should be provided with
48
\fB\-\-volfile\-server\fR option (the default is 1).
54
Mount the filesystem with POSIX ACL support.
56
\fB\-\-localtime\-logging\fR
57
Enable localtime log timestamps.
60
Run in debug mode. This option sets \fB\-\-no\-daemon\fR, \fB\-\-log\-level\fR to DEBUG,
61
and \fB\-\-log\-file\fR to console.
63
\fB\-\-enable\-ino32=BOOL\fR
64
Use 32-bit inodes when mounting to workaround application that doesn't support 64-bit inodes.
66
\fB\-\-fopen\-keep\-cache[=BOOL]\fR
67
Do not purge the cache on file open (default: false).
69
\fB\-\-mac\-compat=BOOL\fR
70
Provide stubs for attributes needed for seamless operation on Macs (the default is off).
72
\fB\-N, \fB\-\-no\-daemon\fR
75
\fB\-p, \fB\-\-pid\-file=PIDFILE\fR
76
File to use as PID file.
79
Mount the file system in 'read-only' mode.
82
Enable SELinux label (extended attributes) support on inodes.
84
\fB\-S, \fB\-\-socket\-file=SOCKFILE\fR
85
File to use as unix-socket.
87
\fB\-\-volfile\-id=KEY\fR
88
Key of the volume file to be fetched from the server.
90
\fB\-\-volfile\-server\-port=PORT\fR
91
Port number of volfile server.
93

94
Transport type to get volume file from server (the default is tcp).
96
\fB\-\-volume\-name=VOLUME\-NAME\fR
97
Volume name to be used for MOUNT-POINT (the default is top most volume in VOLUME-FILE).
100
Mount the filesystem in 'worm' mode.
102
\fB\-\-xlator\-option=VOLUME\-NAME.OPTION=VALUE\fR
103
