I'm migrating about 3,000 accounts to a new machine that will be running qmail/vpopmail, so there will be a directory for each domain, each user, each user's mailbox, etc. and since it's all Maildir instead of spools, there will be a ton of files. Hopefully the box will grow to a few thousand more boxes if we're lucky. How should I go about determining the number of inodes and the blocksize? Does anyone have any general pointers? So far I've been looking at some postings by Joe Greco from the really old days and just treating this the same way I would have treated a news server, but I'd appreciate some more specific feedback from people running a similar configuration. Even some "df -i's" of similarly-sized boxes would give me a good start. Any input at all is welcome. Thanks, Charles
