NAME

6       GlusterFS - clustered file system
7

SYNOPSIS

9       glusterfs [options] [mountpoint]
10

DESCRIPTION

12       GlusterFS  is  a  clustered  file system, capable of scaling to several
13       peta-bytes.  It aggregates various storage bricks over Infiniband  RDMA
14       or TCP/IP and interconnect into one large parallel network file system.
15       Storage bricks can be made of any commodity hardware,  such  as  x86-64
16       server with SATA-II RAID and Infiniband HBA.
17
18       GlusterFS  is fully POSIX compliant file system. On client side, it has
19       dependency on FUSE package, on server side, it works seemlessly on dif‐
20       ferent   operating  systems.   Currently  supported  on  GNU/Linux  and
21       Solaris.

OPTIONS

25   Basic options
26       -f, --volfile=VOLUME-FILE
27              File to use as VOLUME-FILE.
28
29       -l, --log-file=LOGFILE
30              File  to   use   for   logging   (the   default   is   <INSTALL-
31              DIR>/var/log/glusterfs/<MOUNT-POINT>.log).
32
33       -L, --log-level=LOGLEVEL
34              Logging  severity.   Valid options are TRACE, DEBUG, INFO, WARN‐
35              ING, ERROR and CRITICAL (the default is INFO).
36
37       -s, --volfile-server=SERVER
38              Server to get the volume from.  This option overrides  --volfile
39              option.
40
41       --volfile-max-fetch-attempts=MAX-ATTEMPTS
42              Maximum number of connect attempts to server. This option should
43              be provided with --volfile-server option (the default is 1).

46   Advanced options
47       --acl  Mount the filesystem with POSIX ACL support.

51
52       --debug

55
56       --enable-ino32=BOOL

58              doesn't support 64-bit inodes.
59
60       --fopen-keep-cache
61              Do not purge the cache on file open.
62
63       --mac-compat=BOOL

66
67       -N, --no-daemon
68              Run in the foreground.

81
82       --volfile-id=KEY
83              Key of the volume file to be fetched from the server.
84
85       --volfile-server-port=PORT

87
88       --volfile-server-transport=TRANSPORT
89              Transport  type  to  get volume file from server (the default is
