31 dbd CNID databases\&. It must be run with appropiate permissions i\&.e\&. as root\&.
34 can be run on active volumes, but
35 \fBdbd \-rf\fR, which wipes the db before rebuilding it, checks and enforces that the chosen volume is not in use\&.
40 Dump CNID database\&. With
41 \fB\-i \fRdump indexes too\&.
48 Compare CNIDs in database with volume, test if \&.AppleDouble directories exist, test if AppleDouble files exist, report orphaned AppleDouble files, report directories inside \&.AppleDouble directories, check name encoding, heck for orphaned CNIDs in database (requires
54 Don\'t check \&.AppleDouble stuff, only check orphaned\&.
59 Don\'t open CNID database, skip CNID checks, only traverse filesystem
67 Sync CNIDSs from database with volume, ensure \&.AppleDouble directories exist, ensure AppleDouble files exist, delete orphaned AppleDouble files, report directories inside \&.AppleDouble directories, check name encoding by roundtripping, delete orphaned CNIDs in database (requires
73 Converts volume from adouble:v2 to adouble:ea
78 Don\'t create \&.AppleDouble stuff, only cleanup orphaned\&.
83 Wipe database and rebuild from IDs stored in AppleDouble files, only available for volumes without
94 Opens the database which triggers any necessary upgrades, then closes and exits\&.
100 Only work on inactive volumes and lock them (exclusive)
105 Rebuild indexes (just for completeness, mostly useless!)
114 In order to be able to run
116 reconstructing the CNIDs in the database from the
118 files, make sure you\'ve run a
120 rebuild sometimes before, where the CNIDs then would have been synched between database and
124 Also be careful about the option
125 \fBnocnidcache\fR\&. Avoid this option if at all possible, because if prevents you from being able to use
127 .SH "CNID BACKGROUND"
129 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 not 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\&.
131 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\&.
