Exchange 2010 DAG Mailbox not synching

Hi

I have  2 exchange 2010 std servers with a dag , one on a 10.0.10.x range and one on 10.0.0.0 range. The server in the 10.0.10.x range is called SERVESTSECMAIL0 and the server on the 10.0.0.x range is called SERVESTSECMAIL .The 10.0.10.x is in a data centre and 10.0.0.x is at our office. We have 4 databases 2 are working great and 2 are not synching, keeps telling us to reseed the database.

Q1) how do we reseed ?
Q2) how to make a copy of the database in the 10.0.0.x to the 10.0.10.x Exchange server ?

please can anybody help.

many thanks

Hi

you can add mailbox database copy simply by right click-ing specific mailbox database and selecting add mailbox database copy.
But i think that you have tried this already and ih you having troubles replicating (seeding) database to DAG members, meybe you should check database health with eseutil to eliminate database errors.

Thanks for the reply . What command will you run with eseutil to check for database errors ?

Do we need to shutdown the databases before we do this?

You dont seem to have a second copy of some databases. The head office one for example.

ESEUTIL /g – Performs an integrity check  of a Database
ESEUTIL /k – Performs a checksum test of a Database
ESEUTIL /p – Repairs a Database when it’s corrupt (and beyond recovery)
first "dismount" specific database before performing database checks.

If everything is ok with database check for required logs:
ESEUTIL /mh
search for LOG REQUIRED and if is: 0-0 then move old logs files to let's say "backup folder" and mount database again.

Now try to resees database and all errors must be gone.

Hi there,

We all know that passive copy is not in good state.
Did you check health of active copy?
And more important, did you try to reseed passive copy again?

First try to reseed passive copy and post errors here if any.

Hi ,

Can you write out the correct procedure to follow to reseed the passive copy ? I've attached more screen shots for you to look at .

Thanks again

Hey there, sorry it took me long to reply I got your contact on the website.

what is the bandwidth you have between the 2 sites?

alphanetworksAuthor Commented:
We have a 4Meg wirelss link between the 2 sites
0
 
AkhaterCommented:
My best guess from the screen shots is that the problem is that you have a lot of log files in the queue and it is failing.

what is the size of the database you are trying to copy?


Here is what I want you to do

1. On the database enable circular logging (right click -> properties -> maintenance tab)
2. dismount mount the DB and wait long enough for all the logs to be cleared
3. Disable circular logging and dismount mount the database again

try to reseed

AkhaterCommented:
I have other questions for you do you have the same drive letters on both servers?
0
 
alphanetworksAuthor Commented:
Yes they are both on drive letter E .

The Database size is 52.7GB and the whole folder where the database is in is 72.3GB .

Must I enable circular loging on the database and then dismount it ?
head-office-database-size.jpg

AkhaterCommented:
Yes please, you have 20 gb log files => 20,000 logs +

this could explain the failure

do the proposed steps please

0
 
alphanetworksAuthor Commented:
ok . how long do I have to wait before I mount the database again ?
0
 
AkhaterCommented:
you don't have to wait, just enable circular logging
dismount and mount it again
then wait about 10 min or so till you are left with only a few megs of log files (none will be older than a few hours ago)

then disable circular logging and dismount mount again
0
 
alphanetworksAuthor Commented:
I've enabled circular logging and dismounted and mounted the database again . It's been almost 20 minutes now and the folder size is still the same. I can't see that the log files are getting smaller .

Please advise ?

disable circular logging - dismount mount
remove the failing copy
enable circular logging - dismount mount
wait
disable circular logging - dismount mount
create a copy again

alphanetworksAuthor Commented:
Ok I've done everything except for creating a new copy because the servestsecmail ( fail over )  server is still showing the copy in EMC . On the servestsecmail0 it's gone . Must I wait until it's gone on both servers ?

I've manged to get the copy on and it showed healthy for 5 minutes and then it went back to failed and suspended .

can you tell me how did you manage to get it on ? did the seeding succeed ? or you just resumed it ?

alphanetworksAuthor Commented:
when I refreshed the EMC the copy was there but it was suspended so then I resumed it and it went to a healthy state and showed up on the other server .

also please go to the event log of your exchange server any relevant errors in the Application log ?

in the event log open applications and services -> Microsoft -> Exchange -> High availabiilty

AkhaterCommented:
oh that's nothing it was never seeded.



let's do something else can you try one more time creating the copy (after you delete the failing one and the files) but initiate it from the TARGET server and not the source
0
 
alphanetworksAuthor Commented:
Ok will try that now

alphanetworksAuthor Commented:
waiting for copy database to be removed from the target server .

The exchange logs has the same message for all the databases :

Hi , just to keep you up to date . We have started moving the mailboxes from the Head Office and Pretoria databases to the stable databases which is Cape Town and Durban . I will let you know once they have completed .

Q: Why does the move request option on a mailbox go away if the mailbox has been moved once ?
0
 
AkhaterCommented:
because a mailbox request already exists for this mailbox, go down to the move requests you will see them all completed, delete them and the option will show again
0
 
alphanetworksAuthor Commented:
Sorry for the delay but it's been a night mare to move all the mail boxes out, just got a few left.
Once this has been done must we just delete the database and create a new one on one side which will be the primary and the create a copy using the wizard

yes that's about it, delete the failing one

Yes . At the moment some e-mails are trying to send out via our head office server 10.0.0.9 and not the data centre one which is 10.0.10.14 . We need to make sure that 10.0.10.14 is the only server that is used to send mail out through DNS . Where do we check that everything is in place ?

alphanetworksAuthor Commented:
Does the head office server that needs to direct mail to the data centre server to send mail out need a send connector ?

I am sorry bro but I need to ask you to open another question for this issue.

It is very hard to keep track of many problems in the same question and, that way, others might be able to help too
