@irtaza9 Is this on a single host or a pool? Are all hosts properly time-synchronized? It it related to just one specific storage device or on any, e.g., is the behavior the same on a locally-created SR? Are there any hung tasks causing unnecessary I/O on that storage device?

@john.c Indeed, John, and I almost forgot that the backup network on each host was actually on a separate, isolated NIC, and not at all on the VLAN.

RE: HA causes reboot of xcp-ng nodes
@john.c Keeping the various network traffic isolated according to specific usage (management, storage, VMs, etc.) is always a good idea. The last system I managed had 10GiB LACP bonds and using VLANs to isolate traffic and that worked fine with a four-node pool running around 80 or so XenDesktop instances per node. Never experienced any congestion issues. Each dom0 had a ton of memory and I believe it was either 8 or 16 VCPUs to make sure there were sufficient compute and memory allocations to allow for sometimes very heavy loads. It also helped that I eventually added GPUs to take on some of the computational load, in particular when some of the VMs were running applications employing heavy graphics.

@carloum70 One option to address the HA error messages: Delete the HA configuration and re-configure it from scratch once the bonds are all configured OK, which it appears you think they now are.
