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 no perl pro (never had to decipher it until this week), 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. Since I'm new to perl, 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 script. I know I'm supposed to
1. stop mail services
2. add the following to my imapd.conf [code]fulldirhash: yes
hashimapspool: yes # optional[/code]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.
