BOS_SETRESTART(8)

NAME

bos_setrestart - Sets when the BOS Server restarts processes

SYNOPSIS

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]

DESCRIPTION

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:

o 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.

o 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
day.

CAUTIONS

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.

OPTIONS

-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 fullyqualified 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
restart.

There are four acceptable values for either type of restart
setting:

o The string "never", which directs the BOS Server never to

perform the indicated type of restart.

o The string "now", which directs the BOS Server to perform the

restart immediately and never again.

o 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.

o 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 understand.

-general

Sets the general restart time.

-newbinary

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).

-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.

EXAMPLES

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

PRIVILEGE REQUIRED

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 included.
