CODA_REPLAY(1)CODA_REPLAY(1)NAMEcoda_replay - Manual reintegration tool
SYNOPSIScoda_replay [ key ] filename
DESCRIPTIONcoda_replay is a tool for manually reintegrating operations done at a
disconnected client. It provides a superset of the functionality of
the tape-archive program, tar(1). The key argument is a string of
characters containing exactly one function letter and possibly one or
more function modifiers. The filename argument specifies the
tar/replay format file containing the operations to be replayed.
The function portion of the key is specified by one of the following
letters:
r Replay all operations specified in the file.
s Strip out non-tar operations from the file and replay only the
tar operations.
t Do not replay but simply list the operations specified in the
file.
The following characters may be used in addition to the letter which
selects the function desired:
v Be verbose about the operations.
h Be harsh in replay, i.e., abort the program if any replayed
operation fails.
coda_replay can handle normal tar files since it invokes tar to perform
create, link, and symlink operations. However, its main purpose is to
replay checkpoint files saved by the Coda cache manager, Venus, during
disconnected operation. These files may contain operations unknown to
tar: setattr, unlink, rename, mkdir, and rmdir. These other operations
are encoded in the tar file by overloading the linkflag and linkname
fields. Consult the replay.h header file for more details.
BUGS
· There is a limit of 100 characters imposed on filename length by tar.
· Filenames in checkpoint files generated by Venus are all relative to
the enclosing volume root.
