dsync replication does not replicate new subfolders
Hello,
Although this issue has been raised in another thread:
https://www.mail-archive.com/dovecot at dovecot.org/msg57281.html
I decided I should create a new one dedicated on it because that thread
includes other issues as well, and the issue in question still remains
unresolved although it is an important one (and I am hoping to attract
Timo's attention on it, too ;-) ).

dsync replication questions
I am running two servers with Dovecot v2.2.12 on CentOS x86_64 (5.10 and
6.5 respectively) and users are virtual over ldap.
I have setup our main internal server (vmail.example.com) with dsync
replication according to the first part of
http://wiki2.dovecot.org/Replication. The second one
(vmail1.example.com) will be the failover server which we want to be a
real-time mirror (but can be

Dovecot Failover
Hello,
Assuming we have two (low traffic) servers (on different data centers)
replicated using dsync, what is the best way to automatically direct
users to the main server when it is up and to the redundant one when the
main server is down?
Using DNS? I've seen that DNS-based failover has generally issues (for

pop3 mailbox mirroring issues using dsync
Hello,
I have setup v2.2.12 to mirror mailboxes between our main mail server
(vmail.example.com) and a failover server (vmail1.example.com).
The problem I have is the behavior of mailboxes used on the main server
(*vmail*) over POP3. I have setup an IMAP account on the failover server
(*vmail1*) on such a mailbox: the mailbox is used on vmail using POP3
and the same is monitored on vmail1

After more googling, I found this bug report with a very recent fix:
https://bugzilla.redhat.com/show_bug.cgi?id=1399487
It seems to me that this may be relevant in our case.
If so, may it be that this fix has not been rolled out to CentOS repos yet?

Urgent: Need to change the location of a directory tree
Hi,
I am running CentOS 7 (fully updated) on a VM. This has a mounted nfs
share (via fstab) (which mounts a remote storage system) on which we
have created the home directories of 2 users
Here are the home directories:
/mynfsmount

|--/user1
|--/user1
We want to move this whole branch from the mounted NFS share to the
local disk.
What is the way to do so?
Would it be enough to create a

remote | local blocks in protocol settings
Hello,
Where can I find detailed documentation on how "remote" & "local" blocks
are used in protocol configuration to provide specific settings for
particular IPs/Names?
I've been searching around (wiki2, Google) but I found very few things.
I also checked in the conf.d directory of the installation and couldn't
find anything.

It's /dev/vda in my case:

I don't see that on VMs that I manage. Some of the physical machines
that I manage do have duplicates in the device.map.

SOS: Production VM not starting!
I am using a VM with CentOS 5.8 x86_64 under KVM. I only have console
access to the VM through a virtual console (web based).
Tonight, after a routine "yum update", I did a "shutdown -r now" due to
kernel update and the VM won't start. See console screenshot vm1.png:

There is an error (which I haven't seen before):

Dsync fails on second sync for folders with dot in the name
I'm in the processes of running our first dsync backup of all users

reliably fail whenever I try a new run:

Thank you Marcelo for replying,
The directory /etc/lvm/cache/ is empty.
And, yes, the UUID matches:
