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.
