always getting "unhealthy VDI chain"
-
I have an delta backup job in xoa, which is backing up 28 VMs. 26 of them has never any problems, 2 of them (different storages, different xenserver hosts) have always (or at least nearly always, as some manual retries did it) this error:
Reason: (unhealthy VDI chain) Job canceled to protect the VDI chain
When I rerun the job for these two machines, sometimes it get's thru. When running it automatically, it never runs thru.
How can I get more detailed information about the real reason. Which logs can show more?
interesting: I even made a copy of the vdi to have that chain thing cut and used the copy (not a fast one or clone) as storage, but the same error occurs. As far as I can see, there is no VDI chain, with no parent or childs. So where could lay the problem?
Any help is welcome!

Have you read the docs? https://xen-orchestra.com/docs/backup_troubleshooting.html#vdi-chain-protection

@Danp - thank you. Yes, I did, but that was not helping in this case.
Found the solution:Both machines are on a hostserver, which has NOT all networks. So the real reason must be a network problem, therefore a quite missleading error message
After moving both VMs to the master of this pool (which is connected to the same network where the xoa resides), everything went fine. Same storage, same vhds.
