- DDEESSCCRRIIPPTTIIOONN
- JJbbuuiilldd is a system manager's utility for the Jaquith system.
- It's purpose is to rebuild Jaquith's disk index from tape in
- the event of disk crash.
-
-
- Jbuild processes a single Jaquith tape by restoring a
- sequence of index (thdr) file, parsing them, and rebuilding
- the tree structure on disk. Several arguments control the
- details of the restoration: The --ffiirrsstt and -last arguments
- limit the range of thdr files which are read from tape. The
- --mmaattcchhppaatthh argument restricts restoration to user file path-
- names which match _p_a_t_h_n_a_m_e. The --nnooiinnddeexx option inhibits
- the rebuilding of the disk index entirely; only the raw thdr
- files are restored.
-
-
- Jbuild is not network-aware since it is not for use by
- clients. It assumes that it has direct access to the
- readers.
-
-
- _d_a_t_e is of the form _D_a_t_e_S_p_e_c[:_T_i_m_e_S_p_e_c]. _T_i_m_e_S_p_e_c is of the
- form [hh[:mm[:ss]]], and _D_a_t_e_S_p_e_c is of the form
- dd-month[-yyyy]. Month is the first 3 letters of the month;
- all others are numbers. The '/' character is a substitute
- for '-' and '.' may be used instead of ':'.
-
-
- FFIILLEESS
- Jbuild creates a temporary work file in the Jaquith root
- called rebuild._p_i_d. The work file will be renamed
- _a_r_c_h/thdr._n_u_m_b_e_r after the thdr file has been restored to
- its archive, or thdr._p_i_d._c_o_u_n_t, if the file appears to be
- bogus.
-
-
- BBUUGGSS
- Jbuild can restore only one volume at a time; several invo-
- cations may be necessary to restore an entire logical
- archive.
