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
/usr/afs/etc/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 /usr/afs/etc/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".
