mounttable

Overview ¶

Command mounttable sends commands to Vanadium mounttable services.

Usage:

mounttable [flags] <command>

The mounttable commands are:

glob        returns all matching entries in the mount table
mount       Mounts a server <name> onto a mount table
unmount     removes server <name> from the mount table
resolvestep takes the next step in resolving a name.
help        Display help for commands or topics

The global flags are:

-v23.namespace.root=[/(dev.v.io:r:vprod:service:mounttabled)@ns.dev.v.io:8101]
  local namespace root; can be repeated to provided multiple roots

-alsologtostderr=true
  log to standard error as well as files
-log_backtrace_at=:0
  when logging hits line file:N, emit a stack trace
-log_dir=
  if non-empty, write log files to this directory
-logtostderr=false
  log to standard error instead of files
-max_stack_buf_size=4292608
  max size in bytes of the buffer to use for logging stack traces
-metadata=<just specify -metadata to activate>
  Displays metadata for the program and exits.
-stderrthreshold=2
  logs at or above this threshold go to stderr
-time=false
  Dump timing information to stderr before exiting the program.
-v=0
  log level for V logs
-v23.credentials=
  directory to use for storing security credentials
-v23.permissions.file=
  specify a perms file as <name>:<permsfile>
-v23.permissions.literal=
  explicitly specify the runtime perms as a JSON-encoded access.Permissions.
  Overrides all --v23.permissions.file flags
-v23.proxy=
  object name of proxy service to use to export services across network
  boundaries
-v23.proxy.limit=0
  max number of proxies to connect to when the policy is to connect to all
  proxies; 0 implies all proxies
-v23.proxy.policy=
  policy for choosing from a set of available proxy instances
-v23.tcp.address=
  address to listen on
-v23.tcp.protocol=
  protocol to listen with
-v23.vtrace.cache-size=1024
  The number of vtrace traces to store in memory
-v23.vtrace.collect-regexp=
  Spans and annotations that match this regular expression will trigger trace
  collection
-v23.vtrace.dump-on-shutdown=true
  If true, dump all stored traces on runtime shutdown
-v23.vtrace.enable-aws-xray=false
  Enable the use of AWS x-ray integration with vtrace
-v23.vtrace.root-span-name=
  Set the name of the root vtrace span created by the runtime at startup
-v23.vtrace.sample-rate=0
  Rate (from 0.0 to 1.0) to sample vtrace traces
-v23.vtrace.v=0
  The verbosity level of the log messages to be captured in traces
-vmodule=
  comma-separated list of globpattern=N settings for filename-filtered logging
  (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns baz or
  *az or b* but not by bar/baz or baz.go or az or b.*
-vpath=
  comma-separated list of regexppattern=N settings for file pathname-filtered
  logging (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns
  foo/bar/baz or fo.*az or oo/ba or b.z but not by foo/bar/baz.go or fo*az

Mounttable glob - returns all matching entries in the mount table ¶

returns all matching entries in the mount table

Usage:

mounttable glob [flags] [<mount name>] <pattern>

<mount name> is a mount name on a mount table. Defaults to namespace root. <pattern> is a glob pattern that is matched against all the entries below the specified mount name.

Mounttable mount ¶

Mounts a server <name> onto a mount table

Usage:

mounttable mount [flags] <mount name> <name> <ttl> [L|M|R]

<mount name> is a mount name on a mount table.

<name> is the rooted object name of the server.

<ttl> is the TTL of the new entry. It is a decimal number followed by a unit suffix (s, m, h). A value of 0s represents an infinite duration.

[L|M|R] are mount options. L indicates that <name> is a leaf. M indicates that <name> is a mounttable. R indicates that existing entries should be removed.

Mounttable unmount ¶

removes server <name> from the mount table

Usage:

mounttable unmount [flags] <mount name> <name>

<mount name> is a mount name on a mount table. <name> is the rooted object name of the server.

Mounttable resolvestep ¶

takes the next step in resolving a name.

Usage:

mounttable resolvestep [flags] <mount name>

<mount name> is a mount name on a mount table.

Mounttable help - Display help for commands or topics ¶

Help with no args displays the usage of the parent command.

Help with args displays the usage of the specified sub-command or help topic.

"help ..." recursively displays help for all commands and topics.

Usage:

mounttable help [flags] [command/topic ...]

[command/topic ...] optionally identifies a specific sub-command or help topic.

The mounttable help flags are:

-style=compact
  The formatting style for help output:
     compact   - Good for compact cmdline output.
     full      - Good for cmdline output, shows all global flags.
     godoc     - Good for godoc processing.
     shortonly - Only output short description.
  Override the default by setting the CMDLINE_STYLE environment variable.
-width=<terminal width>
  Format output to this target width in runes, or unlimited if width < 0.
  Defaults to the terminal width if available.  Override the default by setting
  the CMDLINE_WIDTH environment variable.
