bos_setrestart - Sets when the BOS Server restarts processes
bos setrestart -server <machine name>
-time <time to restart server> [-general] [-newbinary]
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos setr -s <machine name> -t <time to restart server>
[-g] [-ne] [-c <cell name>] [-no] [-l] [-h]
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 the -server argument performs two types of restarts:
· A general restart. By default, once per week the BOS Server
restarts 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). The default
setting is 4:00 a.m. each Sunday morning.
· 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 general restarts).
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 bos(8).
-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
There are four acceptable values for either type of restart
· 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 bos(8).
Assigns the unprivileged identity "anonymous" to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
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
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 flag is
