HA with 3 distant Storage Pool and 2 XCP-ng in cluster
-
Hello !
I've tree question about how work clusters.
First i will describe the situation :
I've 3 differents places, connect with SD-WAN.
In all places there will be a NAS for shared storage who will be part of the cluster.
Only 3 places will have a server XCP-ng in cluster.So my questions are :
1- In case of one of my shared storage failed, how does the VM to migrate to the one of my other storage Pool ?
2- If the link between one of my place with a XCP-ng and Storage Pool failed, how does the VM to migrate to the one of my other storage Pool ?
3- If the link between one of my place with a XCP-ng and Storage Pool failed, both XCP-ng can't reach each other so did the VM migrate and both can use it with his own storage and when the link became UP again both Pool synchronize information ?
Any help would be appreciated ! Thanks in advense for replying,

If a shared storage fails, it means the VM disk can't be used anywhere. If a compute host fails, no problem, the VM will be restarted elsewhere.

@olivierlambert Thanks for replying !
Is there any solution available in XCP-ng to have multiple Storage Share HA ?

Nope, that doesn't exist at the moment. But I'm not certain how that would work exactly, at least I've not thought about it here.
