Hello,

I hope someone can help me, we have been noticing some issues with the DFS
in Prod and its not looking to good.

DFS Setup comprises of 6 servers, 4 referal servers and 2 servers which host
the data, 400gb of data in todal A Node & B Node across 2 data centers - So 3
Servers per Data Center across quite a fast link, i.e. file copy a GB in 3
mins.

In recent weeks users have been reporting that the data isnt consistant
across the 2 sites and after investigations it would appear that they are
correct.

I have run FRSDiag.exe on the 2 servers hosting the data and have the
following outputs:-

A Node

NtFrs 04/01/2008 20:12:12 Warning 13520 The File Replication Service moved
the preexisting files in e:\production\citrixim to
e:\production\citrixim\NtFrs_PreExisting___See_EventLog. The File
Replication Service may delete the files in
e:\production\citrixim\NtFrs_PreExisting___See_EventLog at any time. Files
can be saved from deletion by copying them out of
e:\production\citrixim\NtFrs_PreExisting___See_EventLog. Copying the files
into e:\production\citrixim may lead to name conflicts if the files already
exist on some other replicating partner. In some cases, the File
Replication Service may copy a file from
e:\production\citrixim\NtFrs_PreExisting___See_EventLog into
e:\production\citrixim instead of replicating the file from some other
replicating partner. Space can be recovered at any time by deleting
the files in e:\production\citrixim\NtFrs_PreExisting___See_EventLog.
NtFrs 04/01/2008 19:39:02 Error 13552 The File Replication Service is unable
to add this computer to the following replica set: "PROD|CITRIXIM"
This could be caused by a number of problems such as: -- an invalid
root path, -- a missing directory, -- a missing disk volume,
-- a file system on the volume that does not support NTFS 5.0 The
information below may help to resolve the problem: Computer DNS name is
"apraafs0xcv.domain.local" Replica set member name is
"{75F45136-2EFB-4CA5-B08B-9109145570A7}" Replica set root path is

"e:\frs-staging" Replica working directory path is "c:\windows\ntfrs\jet"
Windows error status code is ERROR_BAD_COMMAND FRS error status code is
FrsErrorResourceInUse Other event log messages may also help determine
the problem. Correct the problem and the service will attempt to restart
replication automatically at a later time.
NtFrs 04/01/2008 19:39:01 Error 13544 The File Replication Service cannot
replicate e:\production\citrixim because it overlaps the replicating
directory e:\production\citrixim.

without cleaning up.
NtFrs 04/01/2008 20:28:23 Warning 13522 The File Replication Service paused
because the staging area is full. Staging files are used to replicate
created, deleted or modified files between partners. FRS will automatically
remove least recently used files from this staging area (in the order of the
longest time since the last access) until the amount of space in use has
dropped below 60 of the staging space-limit, after which replication will
resume. If this condition occurs frequently: Confirm that all
direct outbound replication partners receiving updates from this member are
online and receiving udpates. Verify that the replication schedule for
receiving partners is open or "on" for a sufficient window of time to
accomodate the number of files being replicated. Consider increasing
the staging area to improve system performance. The current value
of the staging space limit is 10240000 KB. To change the staging space
limit, run regedit: Click on Start -> Run and type REGEDT . Expand
HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Services, NtFrs, Parameters,
and the value "Staging Space Limit in KB".

Can anyone help me determin what these outputs are saying?

I also am running MS Ultrasound which keeps mentioning about Morphed
Directories exist, Very old back logged files, FRS replica set in State
Stopped, Ive Up'd the FRS Staging to 20gb.

Also how can I check the consistancy of the c:\windows\ntfrs\jet\ntfrs.jdb

PLease get back with anything that might assist me with regards to
corrective actions

Many Thanks
