Does anyone know if there is a way to exclude a single volume when replicating a VMware Guest? The reason for this is the disk i/o on this server is so high that the replication of the pre-seeded disk never completes. What we want to do is exclude the disk with the high i/o and if necessary restore that volume from backup if needed. I know this is not true failover if something happens, but we cannot get that volume to replicate.
You mention pre-seeding, so I want to clarify what you’ve done so far. You have tried copying the VM to a portable drive and taking it to the target location and uploading it there. Then, in Zerto Virtual Replication, you mapped the source VM volumes to the target location of the .vmdks (or vhds) and tried to let Zerto perform a delta sync and it’s not completing. Correct?
Also, you can exclude volumes from replicating by identifying them as swap disks when you edit a VM in a VPG. This will tell Zerto not to replicate that volume (after the initial replication completes). See: http://s3.amazonaws.com/zertodownload_docs/Latest/Zerto%20Virtual%20Replication%20Zerto%20Virtual%20Manager%20%28ZVM%29%20-%20vSphere%20Online%20Help/index.html#page/ScreenReference%2FConfigureVolume.html
Correct, I copied the VM to the remote location, loaded up the vmdk and pointed the disk to the pre-seeded volume. The initial sync will never complete, it just keeps going and going, sometimes will go to around 33% and then just starts over again and never completes.
I’d recommend you open a case with Zerto support and let them look at it. They can help you figure out the bottleneck and some possible corrective actions to get it working.
I did contact support about this and we did some configuration planning and it turns out that this particular server needs at least 40MB’s between the sites to allow the sync, just this server alone, not to mention all the others we have. Since assigning 40MB just to one server is not possible we were trying other alternatives. Just cant get this server to replicate.
When will the ability to exclude completely, be available? I have immediate need to exclude a disk and not have to mess with the swap or initial sync. 2tb disk? It won’t sync….ever
