.SH "WARNING"
.PP
If you want/need to run an \-r \-f rebuild after adding \'cachecnid\' to a volume configuration, you must run a rebuild with \-r alone at first in order to sync all existing CNIDs from the db to the AppleDouble files!
.SH "CNID BACKGROUND"
.PP
The CNID backends maintains name to ID mappings\&. If you change a filename outside afpd(8) (shell, samba), the CNID db will not know and doesn\'t reflect that change\&. Netatalk tries to recover from such inconsistencies as gracefully as possible\&. The mechanisms to resolve such inconsistencies may fail sometimes, though, as this is not an easy task to accomplish\&. E\&.g\&. if several names in the path to the file or directory have changed, things may go wrong\&.
.PP
If you change a lot of filenames at once, chances are higher that the afpds fallback mechanisms fail, i\&.e\&. files will be assigned new IDs, even though the file hasn\'t changed\&.
