[Dovecot] FTS indexing
I'm reacreating all FTS indices on all my users' INBOX folders:
mkdir ~%s/Maildir/lucene-indexes && chown %s:users ~%s/Maildir/lucene-indexes doveadm index -u %s -q INBOX
In "ps auxwww" I'm seeing this:
tbudkevy 29186 3.7 0.0 6616 3056 ? S 18:11 0:15 dovecot/indexer-worker [tschuetz INBOX]
how can a dovecot/indexer-worker actually access the INBOX of the user "tschuetz" (where "tbudkevy" doesn't have access, due to the different UID)...?
Should ~%s/Maildir/lucene-indexes be filled after having run the command sequence for all users?

You shouldn't need to do this. It's created automatically. Also by "recreating" do you mean that the users already had Lucene indexes and you deleted them?

indexer-worker runs basically as chroot, but it doesn't bother switching back to root immediately. My guess is that this was a very brief race condition in ps between reading process's UID and the command line. Unless you can easily reproduce this?

Only if there was something in the INBOX. Also if users already had previous Lucene indexes it doesn't work, you need to run doveadm fts rescan because dovecot.index remembers which message was last indexed to Lucene.

There weren't any. That's why I tried creating them!

Can't :)

My users ALWAYS have something in their inbox :)

OK; I'll try that. Where do I finde the lucene index? I didn't find any trace of ~%s/Maildir/lucene-indexes so I was worried and tried to create the directories.

I fucked up royally: I somehow managed to have fts but not fts_lucene in my list of plugins...

It should log errors about that if plugin { fts=lucene } I think?

Well, I somehow managed to sprinkle the plugin lines in such a way that no error was triggered. Now I put fts and fts_lucene into mail_plugins and everything works.
