Re: public and private mailboxes randomly dismounting

OK, so it's not an excessive number of log files either. I was wondering
because you suggested backups had stopped working, it appears however that
you have been able to perform a backup recently, all your logs are commited
previous to today.

You should also exclude the STM (Streaming) data from AV. The 'store' is the
combined edb+stm.

You don't mention anything about logs (System or Application Event Logs),
anything in there at the times the store goes down?

I'd be tempted to now copy the store somewhere (after dismounting, or
stopping services) and see the result of integrity check of the current
store. I'll post some links but I'm working on something else at the moment.

As of now, I have excluded the extensions: edb, log and chk from being
scanned by the AV. I don't know whether this change will make an impact.
However, how can I test it without waiting a full day?

For your question:
Do you have other partitions or are you just running a single part (C:)?
A/ Single partition on the C:


For your statement:
"With your available space it may be worthwhile stopping the Exchange
services and making a complete copy of the mdbdata folder. We can then
repair/recover the existing store and if we lose significant amounts of
data
possibly mount the copy to retrieve missing bits."
if the AV is not the issue causing those random dismounts, how can we
start
the process of repair/recover of the edb?

TIA

You're not hitting a limit based on those sizes. By default the Exchange
logs are located in the same folder, how many logfiles do you have?

Other thing would be to ensure your AntiVirus is not scannng the store
files.

Either way I'd be inclined to create a new folder for the store, exclude
it
and the current folder from AV, and attempt to move both the store and
logfiles to it (using Exchange System Manager). If the move fails it
should
retain the existing store/log location and our next move would be
creation
of a 'dialtone store' then exmerge from the current store mounted as a
recovery storage group into the newly created store. THIS BREAKS 'Single
Instance Storage' and should be avoided but if my _guess_ is correct it
may
be an easy way to get back to a known good state. There are other options
regarding repairing rather than 'tossing' the existing store. I suspect
that
something in the store is corrupt, your random stops are occurring when
some
process (user activity or a management process) is attempting to access
the
corrupt area of the store. It is likely that repair operations on the
store
will result in loss of some information.

With your available space it may be worthwhile stopping the Exchange
services and making a complete copy of the mdbdata folder. We can then
repair/recover the existing store and if we lose significant amounts of
data
possibly mount the copy to retrieve missing bits.

Larry, thank you for responding.

For your questions, here is what I could gather:
from the c:\Program Files\Exchsrvr\MDBDATA
the priv1.edb = 9,818,184 kb
the priv1.stm = 520,200 kb
the pub1.edb = 28,680 kb
the pub1.stm = 2,056 kb

The partition has 1tb of space and 750gb available.


Let me know, if I could provide you more information

TIA

Hi:

How big is the exchange store, and how much room is available on the

Hello,

My company is hosting an exchange environment under win 2003 sbs.
We're
experiencing a random problem. The public and private mailboxes
keep
dismounting. Every time it happens, I access the server and mount
the
public and private mailboxes by going to the
domain(exchange)\servers\myserver\first storage group\ and
everything
works ok after that process. I noticed the daily backup has stopped
working. I don't know, if there's any relation between these two
applications.

I was following a thread from Robert Li "exchange infromation store
won't
mount URGENT HELP GREATLY APPRECIATED." I tried running the
following
command eseutil /mh. I got the follwing:

"c:\Program Files\Exchsrvr\bin>eseutil /mh "c:\program
files\exchsrvr\mdbdata\priv1.edb"

Microsoft(R) Exchange Server Database Utilities
Version 6.5
Copyright (C) Microsoft corporation. All Rights Reserved.

Initiating FILE DUMP mode...
Database: c:\program files\exchsrvr\mdbdata\priv1.edb

Operation terminated with error -1032 (JET_errFileAccessDenied,
cannot
access fi
le, the file is locked or in use) after 33.47 seconds.


Questions:
1) Because the backup hasn't worked for a long time, just in case of
a
major disaster, how and what can I backup manually for the exchange
database including logs?
2) How can I checked the integrety of the exchange database?


Your help is appreciated
