Hello All, If I change the mdbox_rotate_size to 100 MB & mdbox_rotate_interval to say 3 days after a year of usage what would be the impact on existing mails and new mails? Thanks/DP

Hello everyone, I am currently evaluating dovecot for our new email production servers (20k+ mailboxes) and found out something strange. I'm using those settings on Dovecot 2.2.4 (x86_64 / Slackware / compiled from sources) mdbox_rotate_size = 128M mdbox_rotate_interval = 1d mdbox_preallocate_space = yes with virtual users and location like : mail_location = mdbox:~/mdbox I don't think the remaining config is relevant but ask me if you need some other parts. Using test accounts for 2 weeks now I've figured that the 128M preallocated space is never '...

...n Mdbox over strace (see at tail of message). As I can see dovecot process opens old storage m.* file, reads it content, opens new temporary file, writes in this one content and rename this new one to m.(*+1). How fast this algorithm works on system with about 10000 users and 5Tb data? I will use mdbox_rotate_interval for delayed expunge but I think that simple delete file in Maildir must be faster than expunge from Mdbox. Please, tell me about real experience work with Mdbox on big loaded systems. ++++++++++++++++ 0.000017 open("/var/vmail/example.org/user/storage/.temp.1362474108.P7152Q0M909647.ma...

...ent? What would happens if I lose indexes? Can I still recover the messages? Reading the doc it seems I would lose all the message flags and all the messages would be in INBOX, is this right? *3? Performance tuning with mdbox* I have read in dovecot archive about using mdbox_rotate_size & mdbox_rotate_interval to balance between a lot of smaill files (like Maildir) or really big files (a "variant" of mbox). I have tested with a big vaule of mdbox_rotate_size (100 MB) and is a complete disaster for backup:if a user delete a message, then a nightly cronjob purges the mailbox (refcount=0) a new md...

...ring how would dovecot convert this, like if i convert all mail from maildir to mdbox it would make many mailbox based on this seetings ? Or in the first convert it would make a big mdbox file and after it it will rotate by day or it would make many boxes just based on size? mdbox_rotate_size = 5m mdbox_rotate_interval = 1d Well, another thing can i make rotate interval happens in a certain time of day? end from where it takes this time ? it rotates at midnight ? Another one!, if i lose the index files what really happens ? Sometimes in my server the index get corrupet and as i am reading mdbox index files held...

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan
