Exchange 2013 dag copy queue length
While it technically should work, it is not recommended to stretch subnets for DAG Networks across the WAN.
If you have multiple huge mailbox databases, you need to do the first one, eat something, then copy back to do the second one.
Do not put multiple databases on a single LUN.
You could easily have a connection over 500ms not experience copy queues if you have only 20 mailboxes with low usage profiles.CopyQueue length (Logs queuing up to be sent to the passive node) ReplayQueue length (Logs queuing up to be replayed to the passive node database) To re-seed a database (remove all the passive contents and re-copy) On the pasive node first suspend the Storage group.Use the command in the three stooges episodes the link below to force cluster to start using the forcequorum option.Step 1 Pre-Stage DAG Computer Account.These networks should be ignored by the DAG for cluster use.Perform the following steps: prison break the final break blogspot Get-DatabaseAvailabilityGroup Set-DatabaseAvailabilityGroup dagname iscsi/Backup/Mgmt NetworkName -IgnoreNetwork:True Finally, lets validate everything.They should be on isolated networks that have no contact with each other.After a bit of investigation I was able to find out that the customer had recently been trying unsuccessfully to create a DAG from his 3 Exchange 2013 SP1 servers.I asked if those changes were documented; the silence was my answer.
D isable or remove your hardware based VSS provider.
But in step 5, you may need to use setup /m:RecoverServer instead of setup /m:RecoverServer, after adding back the DAG members, you need to force it to reseed.
Disable the Computer Account.
This means if the NICs are configured correctly then you should not have to manually collapse the DAG Networks post DAG Setup.Sometimes it can work out for you but sometimes it can leave you in a state where youre worse off than when you started.The resulting report contains 2 sections; the current mounted databases, and the database replication status.Move all Databases to one node before running backup.You can resolve this in one of 3 ways.The procedure is in this link:.But Exchange is still refuse to start because the mailbox database copy in Machine_A is not the latest version.According to our Networking Development Groups, the recommendation actually is that on-link routes should be added with a entry for the next hop, not with the local address (particularly because the local address might be deleted) and with the interface specified.However, because you should only have 1 Default Gateway configured per server, DAG nodes in each site would be unable to communicate with each other over the Replication networks.Reported As, failed, alert, seeding, warning, seedingSource.Initializing, warning, resynchronizing, warning, mounted, healthy, dismounted.Exchange Trusted Subsystem, managed Availability Servers, eventually I found that the Exchange Install Domain Servers group had been added as a member of the Domain Admins group during the customers troubleshooting efforts to get all their servers added as DAG members.When you add servers to a DAG it will create a network for every subnetNIC that server is connected to, this is nice because as soon as you add the server it can replicate with the other nodes.Custom thresholds can be set for copy and replay log coloring for warnings and alerts.
