Hi,
We are experiencing issues with our DFSR replication. We have 1 volume which is about 5.4TB in size on a Windows 2008 R2 server. The replication fails with the following message
The description for Event ID ( 2104 ) in Source ( DFSR ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: 535EBA43-87FD-4231-AB37-0BA51B8F5104, D:, 9214, Internal database error, -1014, D:\System Volume Information\DFSR.
The response from Microsoft was as below and that we are running an unsupported solution and are refusing to support us any further. Can anyone please comment on sizes and support?
To exceed the 10TB limit – which again, is not supported nor recommended – seriously consider:
1. High reliability fabric to high reliability storage – i.e. do not use
iSCSI. Do not use cheap disk arrays. Dedicated fiber or similar networks only with redundant paths, to a properly redundant storage array that costs a poop-load of money.
2. Store no more than 2TB per volume – There is one DFSR database per volume, which means if there is a dirty shutdown, recovery affects all replicated data on that volume.
1TB max would be better.
3. Latest DFSR hotfixes at all times –
http://support.microsoft.com/kb/968429. This especially includes
using http://support.microsoft.com/kb/2663685, combined with
read-only replication when possible.
Points 1 & 2 are very alarming and make DFSR almost an unusable product if this statement is true.
Many thanks in advance
