DESCRIPTION

       The vos offline command takes a volume offline on the fileserver.

CAUTIONS

       Taking a volume offline that has existing callbacks will result in those callbacks being broken and clients not being able to access the
       volume.

OPTIONS

       -server <machine name>
	   Identifies the file server machine where the volume resides.  Provide the machine's IP address or its host name (either fully qualified
	   or using an unambiguous abbreviation). For details, see vos(1).

       -partition <partition name>
	   Identifies the partition where the volume resides, on the file server machine named by the -server argument. Provide the partition's
	   complete name with preceding slash (for example, "/vicepa") or use one of the three acceptable abbreviated forms. For details, see
	   vos(1).

       -id <volume name or ID>
	   Specifies either the complete name or volume ID number of the volume.

       -sleep <seconds to sleep>
	   Specifies to sleep for a certain number of seconds after taking the volume offline before bringing it online again. If this option is
	   specified, the volume will be online when vos offline successfully completes. If this option is not specified, vos online must be run
	   to bring the volume online.

       -busy
	   Specifies to mark the volume as `busy' instead of `offline'. This means that a program trying to access this volume will receive a
	   VBUSY error instead of a VOFFLINE error (until the volume is brought back online).

	   Different programs may react differently when they see these two different states, but in general a `busy' volume is only unavailable
	   for a short period of time and will become online soon. An `offline' volume, on the other hand, is typically unavailable for longer
	   periods and may not come back online until an administrator intervenes.

	   As an example of when these states occur normally, a volume can be `busy' when it is being cloned (perhaps as the result of a vos
	   backup or vos release operation). A volume can be `offline' if a non-DAFS fileserver has detected a problem in the volume, and an
	   administrator must manually schedule a salvage for that volume before it becomes available again.

	   If -busy is specified, the -sleep option must also be specified, to indicate for how long to keep the volume busy.

       -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 vos(1).

       -noauth
	   Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see
	   vos(1).

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The vos command interpreter presents it to the
	   Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the -cell argument or -noauth
	   flag. For more details, see vos(1).

       -verbose
	   Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and
	   error messages appear.

       -encrypt
	   Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in
	   OpenAFS versions 1.4.11 or later and 1.5.60 or later.

       -noresolve
	   Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or
	   when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following example takes an online volume offline:

	  % vos offline -server sv7.stateu.edu -partition /vicepb -id root.afs

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on the machine specified with the -server argument and on each database
       server machine. If the -localauth flag is included, the issuer must instead be logged on to a server machine as the local superuser "root".
