NAME

       fs_discon - Manage client "disconnected mode"

SYNOPSIS

       fs discon -mode <offline | online>
           [-policy <client | server>]
           [-force]
           [-uid <uid>]
           [-help]

       fs disc -m <offline | online>
           [-p <client | server>]
           [-f]
           [-u <uid>]
           [-h]

DESCRIPTION

       The fs discon command configures "disconnected mode" in the OpenAFS Cache Manager. Disconnected mode
       allows you to keep reading and writing files in AFS without a network connection, and any changes to
       files are recorded locally.  When the network connection is restored and disconnected mode is turned off,
       any locally recorded changes are sent to the relevant server.

       This command was introduced in OpenAFS 1.5.38.

CAUTIONS

       The "disconnected mode" of the OpenAFS cache manager is still considered an experimental feature. It can
       be a bit rough around the edges, and you may lose or corrupt data you have written while in disconnected
       mode. Use with caution.

OPTIONS

       -mode <offline | online>
           This turns "disconnected mode" on or off. If "offline" is specified, the client will go into
           disconnected mode, and the client will no longer make any effort to reach any server over the
           network.

           If "online" is specified, the client will come out of disconnected mode, and any pending changes will
           be sent to the relevant server. If there are errors when synchronizing changes to the server, the
           client will stay in disconnected mode, unless the -force flag is also given. See -force.

       -policy <client | server>
           This specifies the conflict resolution policy when resynchronizing data afer coming back online. A
           conflict resolution policy is needed when changes have been made locally on the client while in
           disconnected mode, and different changes have occurred on the server while we were in disconnected
           mode. When this happens, there are two different possible results:

           If "client" is specified, the local changes on the client will overwrite any conflicting changes on
           the server. This means that if we change a file locally while in disconnected mode, and another user
           changes the same file in the same place on the fileserver while we are disconnected, the other user's
           changes will be lost.

           If "server" is specified, the conflicting changes on the server will overwrite our local changes.
           This means that if we change a file locally while in disconnected mode, and another user changes the
           same file in the same place on the fileserver while we are disconnected, our local changes will be
           lost.

           The default value is "server".

       -force
           If -force is specified when coming back online, any errors during resynchronization are ignored by
           throwing away our local changes. That is, if we write our local pending changes to a server while
           coming back online, and there is an error while writing those changes, those changes will be lost.

           Without -force, such an error causes the client to stay offline.

       -uid <uid>
           When resynchronizing local pending changes to the relevant fileserver, by default we use the
           credentials of the user issuing fs discon to send the changes to the fileserver. If -uid is
           specified, we will instead use the credentials for the specified uid.

           Note that this will only use the PAG-less credentials of the specified uid. It is currently not
           possible to specify an arbitrary PAG here.

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

PRIVILEGE REQUIRED

       The issuer must be logged in as the local superuser "root".
