bos_status - Displays the status of server processes
bos status -server <machine name>
[-instance <server process name>+] [-long]
[-cell <cell name>] [-noauth]
[-localauth] [-help]
bos stat -s <machine name>
[-i <server process name>+] [-lon]
[-c <cell name>] [-n] [-loc]
[-h]
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
- -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 or
/etc/openafs/server/KeyFileExt 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.
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.
The following example command displays the status of processes on
the machine fs3.example.com:
% bos status fs3.example.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.
The following example command displays a detailed status report
for the fs and ptserver processes on the machine
fs1.example.com.
% bos status -server fs1.example.com -instance fs ptserver -long
Instance fs, (type is fs), currently running normally.
Auxiliary status is: file server running.
