Re: Dovecot 2.3.8 - How to force index creation for user/mailbox?

[Tomek Lutelmowski via dovecot]

Someone who have mailbox in different directory than indexes, can confirm
if doveadm can recreate index (after deleting dovecot.index* files) or
these files can be created only by connecting with IMAP client?

can't spot anything obvious wrong. Just spotted that you are storing mails in 
users home root along with all other files such as index files.

Maybe you should store the mailbox contents into Maildir:~/Maildir under the 
users home and index to ~/index/

Re: Dovecot 2.3.8 - How to force index creation for user/mailbox?

[Tomek Lutelmowski via dovecot]

Neither of dovecot.index files are created (.cache, .log, .thread) - these
files are created when I open the folder with IMAP client. When mailbox is
not used for long time, the indexing takes very long time. So I'm looking
for any solution (preferably with doveadm) to manually reindex folders in
background.

Wait, did you mean 'dovecot.index' file? That file is only created 
occasionally, the actual index is kept in dovecot.index.log.

Thanks, but both commands didn't create dovecot.index. Only when I open
folder with IMAP client, the dovecot.index is created.

Try first 'doveadm fetch -u victim body ALL'. If this does not produce any 
useful results, try 'doveadm force-resync -u victim "*"'.

Dovecot 2.3.8 - How to force index creation for user/mailbox?

[Tomek Lutelmowski via dovecot]

Hello,

I'm using maildirs, and I have problems with big mailboxes (~ 2 emails,
30-50GB) - sometimes access to such mailbox takes very long (~10 minutes),
I would like to be able to create index for mailbox in background, but I
couldn't find any way to do it. So far I tried:


*doveadm -D -vvv index -u user 'Folder'  *

But even if this folder have no dovecot.index* files - I always get:

doveadm(user): Info: Wersje robocze: Cache is already up to date

It seems that doveadm doesn't actually checks if the index is present. The
index is created only when I log with IMAP client and check the folder.

So i tried:

*doveadm mailbox cache purge -u user 'Folder' *

No joy either:
doveadm(user): Error: Cache is unusable

And command below doesn't actually do anything to index:

*doveadm  -vvv force-resync -u user 'Folder'*

Is there any way to use doveadm tool to create/fix index? Shouldn't the
index be updated on each email arrival?

Cheers,
TomekL
