The bos setrestart
command records in the /etc/openafs/BosConfig
file the times at which the BOS Server running on the server machine named by
argument performs two types of restarts:
- A general restart. The BOS Server will restart
itself, and then any AFS process marked with the "Run" status
flag in the BosConfig file (equivalent in effect to issuing the
bos restart command with the -bosserver flag) at this time
each week. By default, in a new bos installation, general restarts are
- A binary restart. By default, once per day the BOS
Server restarts any currently running process for which the timestamp on
the binary file in the /usr/lib/openafs directory is later than the
time the process last started or restarted. The default is 5:00 a.m. each
Restarting a process makes it unavailable for a period of time. The fs
process has potentially the longest outage, depending on how many volumes the
file server machine houses (the File Server and Volume Server reattach each
volume when they restart). The default settings are designed to coincide with
periods of low usage, so that the restarts disturb the smallest possible
number of users.
If the setting specified with the -time
argument is within one hour of
the current time, the BOS Server does not restart any processes until the next
applicable opportunity (the next day for binary restarts, or the next week for
The command changes only one type of restart setting at a time; issue the
command twice to change both settings.
- -server <machine name>
- Indicates the server machine on which to set a new restart
time. Identify the machine by IP address or its host name (either
fully-qualified or abbreviated unambiguously). For details, see
- -time <time to restart server>
- Specifies the restart time. By convention the general
restart is defined as weekly (specifies both a day and a time), and the
binary restart is defined as daily (specifies only a time). However, it is
acceptable to define a daily general restart or weekly binary restart.
There are four acceptable values for either type of restart setting:
- The string "never", which directs the BOS Server
never to perform the indicated type of restart.
- The string "now", which directs the BOS Server to
perform the restart immediately and never again.
- A time of day (the conventional type of value for the
binary restart time). Separate the hours and minutes with a colon (
hh:MM), an use either 24-hour format, or a value in the range from
"1:00" through "12:59" with the addition of
"am" or "pm". For example, both "14:30" and
"2:30 pm" indicate 2:30 in the afternoon. Surround this
parameter with double quotes ("") if it contains a space.
- A day of the week and time of day, separated by a space and
surrounded with double quotes (""). This is the conventional
type of value for the general restart. For the day, provide either the
whole name or the first three letters, all in lowercase letters
("sunday" or "sun", "thursday" or
"thu", and so on). For the time, use the same format as when
specifying the time alone.
If desired, precede a time or day and time definition with the string
"every" or "at". These words do not change the meaning,
but possibly make the output of the bos getrestart
command easier to
- Sets the general restart time.
- Sets the binary restart time.
- -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 following command sets the general restart time on the machine
"fs4.abc.com" to Saturday at 3:30 am.
% bos setrestart -server fs4.abc.com -time "sat 3:30" -general
The following command sets the binary restart time on the machine
"fs6.abc.com" to 11:45 pm.
% bos setrestart -server fs6.abc.com -time 23:45 -newbinary
The issuer must be listed in the /etc/openafs/server/UserList
file on the
machine named by the -server
argument, or must be logged onto a server
machine as the local superuser "root" if the -localauth
