.SH DESCRIPTION
|
|
.sp
|
|
\fBmount.ceph\fP is a simple helper for mounting the Ceph file system on
|
|
a Linux host. The only real purpose it serves is to resolve monitor
|
|
hostname(s) into IP addresses; the Linux kernel client component does
|
|
most of the real work. In fact, it is possible to mount a Ceph file
|
|
system without mount.ceph by specifying monitor address(es) by IP:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount \-t ceph 1.2.3.4:/ mountpoint
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
Each monitor address monaddr takes the form host[:port]. If the port
|
|
is not specified, the Ceph default of 6789 is assumed.
|
|
.sp
|
|
Multiple monitor addresses can be separated by commas. Only one
|
|
responsible monitor is needed to successfully mount; the client will
|
|
learn about all monitors from any responsive monitor. However, it is a
|
|
good idea to specify more than one in case one happens to be down at
|
|
the time of mount.
|
|
.sp
|
|
A subdirectory subdir may be specified if a subset of the file system
|
|
is to be mounted.

.SH EXAMPLES
|
|
.sp
|
|
Mount the full file system:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount.ceph monhost:/ /mnt/foo
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
If there are multiple monitors:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount.ceph monhost1,monhost2,monhost3:/ /mnt/foo
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
If \fBceph\-mon\fP(8) is running on a non\-standard
|
|
port:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount.ceph monhost1:7000,monhost2:7000,monhost3:7000:/ /mnt/foo
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
To mount only part of the namespace:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount.ceph monhost1:/some/small/thing /mnt/thing
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
Assuming mount.ceph(8) is installed properly, it should be
|
|
automatically invoked by mount(8) like so:
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mount \-t ceph monhost:/ /mnt/foo
|
|
.ft P
|
|
.fi
|
|
.SH AVAILABILITY
|
|
.sp
|
|
\fBmount.ceph\fP is part of the Ceph distributed file system. Please
|
|
refer to the Ceph wiki at \fI\%http://ceph.newdream.net/wiki\fP for more
