similar to: Single instance storage - testing please

Ok, didn't find much on this... The bottom of /etc/dovecot/conf.d/10-mail.conf has the following settings: #mail_attachment_dir = #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} all of which are apparently the defaults according to doveconf -d output - so no need to set them explicitly, unless I want to change them, right? So, enable the

Hi all, I'm running dovecot 2.3.7.1, with mdbox and single instance storage. I use offline deduplication like this: mail_attachment_fs = sis-queue /mailboxes/%d/_attachments_/queue:posix Each week I run doveadm sis deduplicate to deduplicate the mail attachments. Everything was fine until I mistakenly run doveadm sis deduplicate twice, simultaneously. I ended up having some error messages

I tried to change: mail_attachment_fs = sis posix to mail_attachment_fs = sis-queue posix and immediately failed with: Failed to initialize user: Namespace '': mdbox: mail_attachment_fs: sis-queue: Parent filesystem not given as parameter Where do I specify the "Parent filesystem"? -- Ralf Hildebrandt Gesch?ftsbereich IT | Abteilung Netzwerk Charit? - Universit?tsmedizin

Hello, We are migrating our dovecot servers from 2.1.9 to 2.1.15 (or 2.2 if there is a stable version soon) and maildir format to mdbox. Looking for mdbox options I have found options: * mail_attachment_dir * mail_attachement_min_size * mail_attachment_fs * mail_attachment_hash but this options are described with the message: # WARNING: This feature hasn't been tested much yet. Use at

??????? Hello everybody, ?? On a Dovecot 2.x, what is the best way to delete an user mailbox when : * all attachments for all users detach in a common directory (mail_attachment_dir = var/mail/attachments ). * attachments use SIS deduplication (mail_attachment_fs = sis posix) * mailbox are in mdbox Trying to delete user mailbox directory (rm) and do the command? : doveadm -v purge -u johndoe ,

Hi, I'm currently running a small home-server with Dovecot. A long time ago I configured it with SIS enabled. I would like to stop using SIS. If I remove sis from mail_attachment_fs will the old mails that are stored in SIS-storage still be accessible? How can I convert all mailboxes to stop using SIS and store attachments back in the mails? Rgds, N.

Having had a week with the system I'm now inclined to believe that the issues I've seen are not necessarily related to SIS and zlib but may be due to replication instead. After experiencing these issues and looking at historical mailing list posts I wrote a basic script (as was suggested as a possible diagnostic approach for SIS before SIS was even implemented!) which pulled all the

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the

Hi, I've been working with dovecot SiS for a long time without any problem. This is my configuration for SiS: mail_attachment_dir = /mail/users/attachments mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} mail_attachment_min_size = 128 k With this configuration, I have, for example: # ls -l /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1* -rw-------

Hi everyone, I tried to find info about this online, but I couldn't find anything talking specifically about what I am trying to accomplish. I am sending and receiving the same attachments pretty often and as a result my email accounts are growing much more rapidly than I would like. *My goal* is to set up a second instance of Dovecot with SIS enabled and transfer everything over to this

We will be deploying a replacement Dovecot server soon, and we are planning to use maildir for the primary storage, but with an archive namespace using mdbox (or perhaps sdbox), and SIS. Our backup servers and (luke)warm spare server need to obtain full copies of the mail store. For the maildirs I know I can simply use rsync (we already use it here). I'm a little wary of using rsync with

Now that v2.0.0 is only waiting for people to report bugs (and me to figure out how to fix them), I've finally had time to start doing what I actually came here (Portugal Telecom/SAPO) to do. :) The idea is to have dbox and mdbox support saving attachments (or MIME parts in general) to separate files, which with some magic gives a possibility to do single instance attachment storage. Comments

This single-instance storage is going to encourage bad habits! I just found myself preparing an e-mail that needs to be sent to multiple recipients - including several within my own organization - yet it's not necessary for everyone (in-house) to get the large attachment. As I was getting ready to split the message into two parts for distribution I remembered - I can just send it to

Hi I migrated my dovecot server from Maildir to mdbox with saving attachments to external files and enabled SIS a few days ago. Everything works fine except one issue. I have both virtual and system users. Dovecot saves attachments with mode 0600. So I catch such errors for system users: dovecot: lda(wasya): Error: fs-sis: Couldn't read hash file

How do you do. I have tried to use SiS to deduplicate attachments in mail storage. Unsuccesful. When goes mail with reasonable size, and SiS try to start, I have receive error, when this mail must be delivered for group of receivers (i.e. through aliases). Below is error log, valuable parts of mail addresses masked by X and Y chars Aug 6 16:11:12 mailsrv dovecot: lmtp(xxxxx):

Thanks Jack. That's good to know. It is definitely something to consider. In a distributed storage scenario we might build a dedicated pool for that and tune the pool as more capacity or performance is needed.
