The bos status command reports the status of processes on the server machine
named by the -server
- All of the AFS server processes listed in the
- Only these processes named by the -instance argument
- -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
- 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
- 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
- Assigns the unprivileged identity "anonymous" to
the issuer. Do not combine this flag with the -localauth flag. For
more details, see bos(8).
- 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).
- Prints the online help for this command. All other valid
options are ignored.
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
- The process's type ("simple", "fs", or
- The day and time the process last started or
- The number of "proc starts", which is how many
times the BOS Server has started or restarted the process since it started
- 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
- 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
- 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.
The following example command displays the status of processes on the machine
% 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
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.
