       fssync-debug, dafssync-debug - Introduction to the fssync-debug command


       The fssync-debug command suite allows low-level inspection and control
       of the file server volume packages.  The dafssync-debug command suite
       is identical to fssync-debug, but is built with demand-attach support.

       This command suite operates at an extremely low-level and hence
       requires detailed knowledge of the OpenAFS architecture and code.  An
       understanding of the OpenAFS volume finite-state machine is required
       before the state of a volume should be manipulated.  Indiscriminate use
       of fssync-debug or dafssync-debug in control mode can lead to extremely
       bad things occurring. Use with care.


       The following arguments and flags are available on many commands in the
       fssync-debug suite. The reference page for each command also lists
       them, but they may be described here in greater detail.

       -volumeid <volume ID>
           Specifies the numeric volume ID. Volume names are not permitted.

       -partition <exact partition name>
           Specifies the exact partition name (e.g. /vicepa). Abbreviations
           are not permitted.

       -reason <sync protocol reason code>
           Specifies numeric sync protocol reason code.  Available codes are
           listed in OpenAFS source file src/vol/fssync_inline.h. For
           SYNC_REASON_NONE, use -reason 0.

       -programtype <program type code>
           Specifies program type code. Permitted values are fileServer,
           volumeUtility, salvager, salvageServer, volumeServer and


       The issuer must have write access to the file server.  Usually, this
       means that the issuer must be the local superuser "root" on the file
       server machine.
