I work at a college where we have about 4500 student mail accounts. Our
Xserve (Tiger 10.4.7) is bound to Active Directory where we're using the
student id # as the username which always begins with a 0 or 1. This causes
the basic hashing scheme to put the /var/imap/___ files in subfolder "q" of
the respective directory (user, quota, ...). We are not using virtual
domains. I would like to rehash to the full hashing scheme using the rehash
script (/usr/bin/cyrus/tools/rehash). I'm neither a bash nor perl expert,
but it appears the rehash script is not compatible with case INsensitive
file systems (like our Mac OS Extended - Journaled). I've made some changes
to the script's move_users subprocedure to create new dirs beginning with
"." (so it wouldn't remove valid dirs) and then after hashing rename all
those "." dirs back to their corresponding letters--just like the
move_quotas and move_sieve subprocedures do. I'm hesitant to run my changes
since there is no easy undo if it doesn't work. (Yes, I know I need a test
box.) If any are interested in seeing my modified rehash script, let me
know. (I've also added a bunch of print statements for debugging.)
Also, I haven't found much documentation on the rehash script. I know I'm
supposed to
1. stop mail services
2. add the following to my imapd.conf
fulldirhash: yes
hashimapspool: yes # optional
3. run sudo -u cyrusimap /usr/bin/cyrus/tools/rehash full
Am I supposed to run anything else (like reconstruct) afterwards before I
start up mail services again?
TIA for any help.
