Replication Failing During Calculating Digests Step

[itfnb]

Last week, I migrated our vSphere VMs to new hosts, but left vCenter and vSphere untouched. All of the Veeam backup jobs, copies, and replications ran flawlessly, though Veeam did have to reread all of the VMs (No biggie, that was expected.).

This week, I migrated Veeam to a new VM, vCenter to a new VM, updated our DR site's vSphere hosts from ESXi 5.1 to the latest 5.5 build (to match the new production hosts), and applied the latest Veeam B&R 7 patch when it was released. The backup jobs and copies worked great.

However...I'm having a bit of an odd behavior on our replications: The proxy VM at our DR site normally has used Hotadd on the host its running on and network for the other host. It's never been a big deal because the WAN connection is the bottleneck. Now, during the "calculating digests" step, it will eventually fail and give an error like this:

Code: Select all

2/15/2014 11:19:22 AM :: Processing 'Replication Job Name' Error: Client error: Failed to open VDDK disk [[datastore] vm_name/vmname-000002.vmdk] ( is read-only mode - [true] )

Failed to process [calcDiskDigestsCli].

The odd thing is that the jobs going to the other DR host through the same proxy, but using nbd are working. ???

FWIW, the jobs that were failing under Hotadd are indeed working in Network mode (The only change I made was to force the DR site's proxy to use Network mode.).

Perhaps some generic hot add issue... try switching this proxy to the network mode for now.

Yeah, it's working under that mode.

Any patch for this issue?

Thank you and best regards,

Do you also use Hot Add mode? Does switching to network mode solves the issue for you? Have you already contacted support team with this problem? Thanks.
