NAME

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

DESCRIPTION

       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.

OPTIONS

       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 volumeSalvager.

PRIVILEGE REQUIRED

       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.
