Error adding host to existing pool
-
You need to have a host that doesn't have any network configured already (outside management), because the config will be wiped and replaced by the destination pool config.
-
@olivierlambert Thank you for your prompt response.
If I understood correctly, the slave host only needs to have the manager network configured.
But I have more vlans that access the shared sr. Do I have to configure these later?
-
As soon your host enters the pool, the network configuration (and storage) will be propagated to the new pool member.
-
@olivierlambert I'll try it!
-
@olivierlambert Now it has been added,
But it has also copied the vlan configurations with the network cards....
Is that so?
If on host 1 in eth1 I had vlan 40 for storage
on host 2 do I have to have it the same?Can't I have it on eth4???
-
No, you have to use the same NIC numbering between the hosts in the pool, that's part of the perk using a pool, the configuration is auto applied on all your hosts.
If you have a different number of NICs you must use interface rename program to try to get them ordered the same at least. If the hardware is too different, then using a pool isn't what you need.
-
@olivierlambert Ok, understood.
The issue is that the current server which is master is the most different from the other 4 we have.
We have this fifth one for testing and migrations.
The others are all the same.
Can VMs be migrated in different pools?
Could one host be changed from master to another once we have the same ones in the same pool??
Thanks in advance.
-
So you can do the opposite if you prefer, create a pool with the other hosts instead. Yes, you can live migrate between pools. Or warm migrate. Anyway, everything is possible, it's just a matter of understanding the pro and cons of using pools.
-
@olivierlambert Thank you very much for the info.
Better this way, I will create a pool with the 4 equal hosts.
-
Yeah I think that's the best approach in your case
