DESCRIPTION¶
The bos status command reports the status of processes on the server machine
named by the
-server argument, either
- •
- All of the AFS server processes listed in the
/etc/openafs/BosConfig file
- •
- Only these processes named by the -instance argument
OPTIONS¶
- -server <machine name>
- Indicates the server machine for which to report server process status.
Identify the machine by IP address or its host name (either
fully-qualified or abbreviated unambiguously). For details, see
bos(8).
- -instance
- Names each process for which to report status. Use the process name
assigned with the -instance argument to the bos command. The
output from the bos status command lists the names.
- -long
- Produces more detailed status information.
- -cell <cell name>
- Names the cell in which to run the command. Do not combine this argument
with the -localauth flag. For more details, see bos(8).
- -noauth
- Assigns the unprivileged identity "anonymous" to the issuer. Do
not combine this flag with the -localauth flag. For more details,
see bos(8).
- -localauth
- Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The bos command
interpreter presents the ticket to the BOS Server during mutual
authentication. Do not combine this flag with the -cell or
-noauth options. For more details, see bos(8).
- -help
- Prints the online help for this command. All other valid options are
ignored.
OUTPUT¶
The output for a process includes at least one line, which reports one of the
following as the process's current status:
- •
- "currently running normally". The process's status flag in the
BosConfig file is "Run". For cron entries, this
message indicates only that the command is scheduled to run, not
necessarily that it was executing when the bos status
command was issued.
- •
- "disabled". The process is not running, and its BosConfig
status flag is "NotRun".
- •
- "temporarily disabled". The process is not running although its
status flag in the BosConfig file is "Run". Either an
administrator used the bos shutdown command to stop it, or
the
- •
- BOS Server stopped trying to restart it after numerous failed attempts. In
the second case, the auxiliary message is "stopped for too many
errors".
- •
- "temporarily enabled". The process is running although its
status flag in the BosConfig file is "NotRun". An
administrator has used the bos startup command to start it.
If one of the following special circumstances applies to the process, the
indicated message appears in its entry:
- •
- "has core file". The process failed and created a core file in
the /var/log/openafs directory. If the BOS Server was able to
restart the process after the failure, the primary status is
"currently running normally".
- •
- "stopped for too many errors". The reason for the primary status
"temporarily disabled" is that the BOS Server's attempts to
restart the process all failed.
The entry for the fs process always includes a second line to report the
process's "Auxiliary status", which is one of the following:
- •
- "file server running". The File Server and Volume Server
components of the File Server process are running normally.
- •
- "salvaging file system". The Salvager is running, so the File
Server and Volume Server are temporarily disabled. The BOS Server restarts
them as soon as the Salvager is finished.
The entry for a cron process includes an "Auxiliary status" that
reports when the command will next execute.
If the -long flag is used, each entry includes the following additional
information:
- •
- The process's type ("simple", "fs", or
"cron").
- •
- The day and time the process last started or restarted.
- •
- The number of "proc starts", which is how many times the BOS
Server has started or restarted the process since it started itself.
- •
- The "Last exit" time when the process (or one of the component
processes in the fs process) last terminated. This line does not
appear if the process has not terminated since the BOS Server
started.
- •
- The "Last error exit" time when the process (or one of the
component processes in the fs process) last failed due to an error.
A further explanation such as "due to shutdown request"
sometimes appears. This line does not appear if the process has not failed
since the BOS Server started.
- •
- Each command that the BOS Server invokes to start the process, as
specified by the -cmd argument to the bos create
command.
- •
- The pathname of the notifier program that the BOS Server invokes when the
process terminates (if any), as specified by the -notifier argument
to the bos create command.
If the -long flag is provided and the BOS Server discovers that the mode bits on
files and subdirectories in the local
/usr/afs directory differ from
the expected values, it prints the following warning message:
Bosserver reports inappropriate access on server directories
The following chart summarizes the expected mode bit settings. A question mark
indicates that the BOS Server does not check that bit.
EXAMPLES¶
The following example command displays the status of processes on the machine
fs3.abc.com:
% bos status fs3.abc.com
Instance buserver, currently running normally.
Instance kaserver, currently running normally.
Instance ptserver, currently running normally.
Instance vlserver, currently running normally.
Instance fs, has core file, currently running normally.
Auxiliary status is: file server running.
Instance upserver, currently running normally.
Instance runntp, currently running normally.
The following example command displays a detailed status report for the
fs and
ptserver processes on the machine
fs1.abc.com.
% bos status -server fs1.abc.com -instance fs ptserver -long
Instance fs, (type is fs), currently running normally.
Auxiliary status is: file server running.
Process last started at Wed Jan 7 5:34:49 1998 (3 proc starts)
Last exit at Wed Jan 7 5:34:49 1998
Last error exit at Wed Jan 7 5:34:49 1998, due to shutdown
request
Command 1 is '/usr/lib/openafs/fileserver'
Command 2 is '/usr/lib/openafs/volserver'
Command 3 is '/usr/lib/openafs/salvager'
Instance ptserver, (type is simple) currently running normally.
Process last started at Tue Jan 6 8:29:19 1998 (1 proc starts)
Command 1 is '/usr/lib/openafs/ptserver'
