Hello Cyrus People. I have been always a proud user of the cyrus email system, currently my larger cyrus installation is about 70K users, which have been working fine, however i need to make some adjustems to improve the resposiviness of the mailstore. At the begining i use only a default mailstore, on a ext3 formatted filesystem over a raid 10 / LVM, it works fine, however when it reaches the 32768 directories, (a limitation of ext3) i have to create another partition, and then another one, so i have currently 3 partitions in total. Having defined some criteria in order to group every user into a partition i will like some recomendations, taking in mind the current cyrus server tools which i currently don't know what are their current capabilities, my plan is to forget using cyrus partitions, and instead using LVM partitions and the propper links to the physical partitions from the logical one. So i currently have: partition-default : 30K users partition-alt1: 20K users partition-alt2 : 20K users. and then i will like to have just one partition: partition-default ext4 formatted with links to physical partitions based on the first letter [a-z] of the user. I think LVM is a great advantage, and in some way aliviate the need for cyrus partitions, i it will lead me deal with the grow of a partition and data administration so easy without too much downtime. So, it means that accordingly to this stragegy which seems to be the most simple for me, what would be the best technical path to accomplish a good migration ? allowusermoves: yes option and renamemailbox is enoguth to do this task ? what if i want to do this online ? can i ? how ? is there any script that will help me do that ? Any suggestions or migration histories are welcome ! What about murder / perdition ? they make any sense in this configuration ? Keep this good work ! Slds. -- Nestor A.
