similar to: DSYNC needs a lot more documentation

I would like to set up an active-active fault tolerance couple of mail servers. Is the following procedure correct? Let's suppose I want to set up two servers for acme.com, mail1.acme.com and mail2.acme.com I declare both servers as MX in DNS configuration. Mailbox are stored in maildir with a single UID/GID owner for all the maildir files Userbase is MySQL, user tables are replicated

OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location =

What does this mean? These lines occur on subsequent runs of "dsync -u user backup target" dsync(dmiller at amfes.com): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync(dmiller at amfes.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. -- Daniel

doveadm already supports some nice things, such as being able to remotely launch a doveadm command via TCP socket. It also supports executing a command for all users or to some specific users using a wildcard. dsync could use these features, so I merged dsync and doveadm into same binary for v2.1. I'll still install "dsync" symlink pointing to "doveadm", and running that

Hello, I'm trying to migrate from maildir++ to mdbox. The maildir++ is a leftover of our previous setup (was using courier) We have 3 virtuals servers for our +70000 accounts. Now, I'd like to use mdbox, so I'm trying using dsync for that. I setup a new virtual server, configured for mdbox. 1st, I tried a basic setup: I established a file with all my accounts (taken from LDAP)

Hi, Using dsync to backup my users' mailboxes (dovecot 2.2.10 on both sides), I sometimes encounter the following issue. Below is the output of: dsync -Dvf -u "user" -R backup ssh root at server.domain.tld dsync -u "user" doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_acl_plugin,

Compiles, but untested for now. It works with one more change on top of your patch: diff --git a/src/doveadm/dsync/dsync-mailbox-export.c

Hi, I try to mirror two dovecots with: dsync -v -f -u login mirror ssh -o IdentityFile=/etc/dovecot/dsync.d/id_rsa root at shrike dsync -u login This usually works, but if I delete a certain number of emails, I get this messages: dsync-local(mailverwalter): Info: Posteingang: Ignored 178 modseq changes dsync-local(mailverwalter): Info: Posteingang: Couldn't keep all uids

Hi, while syncing dsync crashed: dsync-local(matthias): Panic: dsync brain state=10 dsync-local(matthias): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0 [0xf7eed541] -> /usr/local/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x4e) [0xf7eed66e] -> /usr/local/lib/dovecot/libdovecot.so.0(i_error+0) [0xf7eed878] -> dsync [0x804e106] -> dsync [0x80539b7] ->

Hello, I thought mdbox was production ready, but it seems to me that (in 2.0.4) it's quite broken. 1) The documentation only running this to convert from maildir to mdbox: *dsync mirror maildir:~/Maildir* but based on my experience and on posts on the mailing list, it's not enough. A namespace has to be defined and it's not clear whether / or . should be used as a separator. I

I think I get pretty much the same issue: dsync(support): Panic: file mailbox-attribute.c: line 360 (mailbox_attribute_get_stream): assertion failed: (value_r->value != NULL || value_r->value_stream != NULL) dsync(support): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0xc9e06) [0x7fba8a348e06] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7fba8a348e4a]

Hi, We have dsync failing once in a while when running in "backup" mode. What's strange is that the result is that the file permissions on the *source* machine ends up with the wrong permissions (set to uid 0). Even though the dsync manual clearly says: "Backup mails from default mail location to location2 (or vice versa, if -R parameter is given). No changes are ever done

Hi, I dont know why dsync requires o+rx in working dir, at least it could give better error message when working dir has o-rwx. # cd # mkdir test # cd test # dsync -D -v -u 'info at example.org' -o 'mail_privileged_group=mail' -o 'mail_location=mbox:/email/info at example.org/mail:INBOX=/var/mail/info at example.org' mirror 'maildir:~/Maildir' dsync(info at

Hello, Some code that I didn?t write but am maintaining passes a local script?s path as dsync?s ?destination? argument, like so: dsync -D -u john -v backup -R -1 "/code/dsync_client.pl" 127.0.0.1 john at mydomain.org dsync_client.pl establishes a TCP connection with a remote dsync process then acts as a proxy between the two dsync processes. ?127.0.0.1? and ?john at mydomain.org?

Hi I understand the crash below is caused by filesystem quota. I just report it because perhaps it could have a more graceful failure.

When a user renames their username, I am using dsync to copy their mail over to the new username's mail location[0]. Some of the dsyncs are failing with errors that I dont know how to work with, for example: dsync(<username>): Error: Trying to open a non-listed mailbox with guid=41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: msg iteration failed: Couldn't open

Hi list, I recently tried to backup mailboxes from an older server machine to a new one in order to move the service to the new machine. Both machines are in the same LAN, I used this command: dsync -R -u username backup ssh -i .ssh/id_rsa username at 192.168.1.11 /opt/local/bin/dsync and I get this error: dsync-local(dz): Error: Invalid server handshake: dsync-server 2 dsync-remote(dz):
