NAME

6       pvfs2tab - information about pvfs2 volumes
7

DESCRIPTION

9       Any  program  that uses PVFS2 will consult a pvfs2tab file for informa‐
10       tion about how to convert a  path  name  into  information  like  which
11       servers to contact and what files to request.
12
13       Programs will look for a pvfs2tab file in several places
14
15       /etc/pvfs2tab
16              The default location of the file
17       pvfs2tab
18              If  there  is no /etc/pvfs2tab file, then a program will look in
19              the current directory for a file called pvfs2tab
20       PVFS2TAB_FILE environment variable
21              This environment variable overrides  any  system-wide  or  local
22              files.   Programs  will  look for a file located at the value of
23              the environment variable.

FORMAT

27       The file format is similar but not identical to fstab  (5),  and  looks
28       like "<bmi_address>/<fs_name> <mountpoint> pvfs2 <options> 0 0"  .
29
30       bmi address
31              Takes the form <protocol>://<hostspec> <protocol> is the name of
32              the communications protocol used by  bmi  ("gm",  "tcp",  "ib").
33              <hostspec>  is  the name of any metadata server.  This format is
34              method-dependent.  For  example,  a  <hostspec>  for  the  "tcp"
35              method  would  look  like "foo.bar.com:2344".  Other methods may
36              express hosts in different ways.
37       <fs_name>
38              is the name of a PVFS file system on that server.
39       <mountpoint>
40              is the virtual mountpoint used by pvfs2 clients.
41       <options>
42              will generally be "default" for a standard set of options.   Two
43              other  options  are  currently  available.   The  option  "flow‐
44              proto=<flow_method>" can be used to specify  an  alternate  flow
45              protocol  method.   The option "encoding=<encoding>" can be used
46              to select a per-file system  wire  encoding  mechanism,  one  of
47              "direct", "le_bfield", or "xdr".
