Name
dbd — CNID database maintenance
Synopsis
dbd [-cfFstuv] [volumepath] dbd [-V]
Description
dbd scans all file and directories of AFP volumes, updating the CNID database of the volume. It must be run with appropriate permissions i.e. as root.
Options
-c convert from AppleDouble v2 to EA filesystem metadata -f delete and recreate CNID database -F location of the afp.conf config file -s scan volume: treat the volume as read only and don’t perform any filesystem modifications -t show statistics while running -u username for use with AFP volumes using user variable $u -v verbose -V display version info
CNID background
The CNID backends maintains name to ID mappings. If you change a filename outside afpd(8) (shell, samba), the CNID database will not reflect that change. Netatalk tries to recover from such inconsistencies as gracefully as possible.
