Re: VMware backup failure
Thanks for providing the requested information. The reported issue is already addressed by VMware and provided patch for the same. Normally this issue occurs in case where after you upgrade to or install VMware ESXi 6.0.x, the following operations might fail or not work as expected on a Change Block Tracking (CBT) enabled virtual machine due to excessive CBT heap exhaustion:
- Virtual machine backup
- Virtual machine Power on
- Expanding the size of the virtual disk
- Taking virtual machine quiesced snapshots
You can observe error log similar to the following in the /var/log/vmkernel.log file:
"<YYYY-MM-DD>T<TIME>.nnnn cpu5:nnnnnn)WARNING: CBT: 191: No memory available! Called from 0xnnnnnnnnnnnn"
The vSphere Client might display an error message similar to the following when you attempt quiesced snapshot:
An error occurred while taking a snapshot: msg.snapshot.error-QUIESCINGERROR

@Finch can you please try quiescing snapshot of the problematic and update us to check further on this issue
