The domains on this server is using a slave-slave setup. This is the only server with dns issue, the other 2 servers which run master-slave/master-slave dont have this issue. There are 3 servers in total I notice that after v-sync a few minutes later it will autodelete the dns zones on both slave servers. Ive tried to delete remote dns and add back a few times, and after a few minute it autodeletes the dnszones. I checked the log and found this 2023-05-18 23:23:05 v-list-dns-records ‘admin’ ‘[domain.com](http://domain.com)’ ‘json’ [Error 3] Im still trying to figure out why it auto deletes but cant seem to fix it. digging into both slave server error log i found the same error v-delete-dns-domain ‘dns-cluster’ ‘domain.comi’ ‘yes’ ‘’ ‘’ ‘’ ‘’ ‘’ [Error 3] ![server setup](https://forum.hestiacp.com/uploads/default/original/2X/3/38ccd74afbf33c4bfffefae5a009a3aca12046e2.jpeg) ---

I have removed 1 of the slaves and it has stopped auto deleting however this is not a proper solution… ---

This server is primary and slave and the most odd thing is that it created a dns zone for a domain that is hosted on the same server as belonging to another server. So say example domain [test.com](http://test.com) is hosted on ns1, and slave is ns2. On ns1 in dns-cluster user there is a dns zone [test.com](http://test.com) with label as ns2. So basically there is a duplicate its hosting the dns entries on the primary server and inside the dns cluster user so 1 server with 2 duplicate dns zones. ---

Another thing i found that the dns cluster user is not presenting the numbers of zones and records correctly ![dns cluster](https://forum.hestiacp.com/uploads/default/original/2X/0/0f3982b2e28b83953c392f0bcaa0cbf77cc65cfc.jpeg) ---

The old way from vesta days. Added picture to explain my dns cluster setup. Host 3 domains are remote-dns to host 1. Does not seem possible to add to host 2 because once i do that it starts deleting all the records on both slave ns1/ns2 ![server setup](https://forum.hestiacp.com/uploads/default/original/2X/3/38ccd74afbf33c4bfffefae5a009a3aca12046e2.jpeg) ---

Do you for host 3 both dns-user? Try creating a new user and assign the DNS user role… ---

I dont understand your reply. Are you suggesting i re-create all dns-cluster users from host 1 and host 2? Or are you suggesting i create a dns-user on host 3 server? ---

I have switch over to the new API way `v-add-remote-dns-host slave.yourhost.com 8083 'accesskey:secretkey' '' 'api' 'dns-user'` I deleted the previous dns cluster user and recreated as dns-user with dns role. In 10 minutes after adding remote dns for host 3, **host 1 and 2 (slave)** starts deleting zone records of **host 3.** Now host 3 dns zones are not hosted anywhere because the slaves keeps auto deleting… ---

I think the bug happens when you add 2 remote slaves for 1 server. I have removed both slaves and now i just add 1 slave and it does not seem to be auto deleting anymore. ---

There is a bug in the DNS documentation: Username should be: dns-cluster or assign the “Role” ![Screenshot 2023-05-20 at 09.48.18](https://forum.hestiacp.com/uploads/default/original/2X/4/4f8d0823492c443d0eac010022237754dbd4b8e5.png) That will prevent it from accidentally syncing… ---

@eris I did both, i added username as dns-user and set role as dns sync user. Do i need to change the username or probably not since i assigned role dns sync user. But the problem still remains, for host 3 i can only add its dns zone to 1 slave so that means there is no redundancy and only 1 name server which generally isn’t good… do you have any idea how to resolve this? ---

v-sync-dns-cluster deletes every dns domain on the user account So make sure to create an unique user for each “server” ---

So you mean for each server the dns cluster username has to be different? **For example server 1** dns-user111 as username **Server 2** dns-user222 as username Is this what you mean? ---

This seems to have resolved the problem, different username for each dns cluster. I never thought about it because the documentation from vesta and hestia always meantion dns-cluster as the user and never crossed my mind that it could be something else other than that. Thanks for your help @eris ---

Yes a unique username is fine… Also update the role off course… ---

My question is a bit off. - Why should we use DNS Cluster? - In what situation should we use it? - And how useful is it? ---
