Change hostname of physical hosts under an oVirt and Gluster combination
Hey All, Would like to change the hostname of hosts within a gluster volume that's been added to oVirt. I also need to readd the bricks to the gluster volume under the new hostname. What's the recommended approach to do so when all this is added to oVirt? -- Thx, TK.
Or in other words, how do I remove all resources, clusters, datacenters, hosts and readd them under different names? Cheers, TK On 9/22/2019 6:48 PM, TomK wrote:

Hey Sahina, Thanks very much. I've taken a quick glance and it does mention I need a third host which I don't have. However, since I wrote, I removed everything. Had to force remove hosts however the gluster setup and data in it stayed (Or so I'm thinking). I'll read the article more thoroughly however is there a specific procedure for adding existing oVirt gluster volumes back into a cluster? One additional question. Is the sequence below correct? 1) Create Data Center 2) Create Cluster within the DC 3) Create a Domain within the Cluster 4) Add hosts to DC 5) Import Gluster Volume Some issues. I create a DC, add a Cluster then add the Host to it. Then I try to add another the second node but it says It's already in a cluster. There is no other cluster and the second host is not listed anywhere. So I try to remove the first host to restart from the beginning. It says I can't remove the only host now till it's in maintenance. Maintenance is grayed out. I wait a bit guessing there's background processes running and can finally remove to readd. When I try to redo the operation and get to the step of adding another host, I get: "Error while executing action: Server mdskvm-p02.nix.mds.xyz is already part of another cluster."

One additional question. Is the sequence below correct?
1) Create Data Center 2) Create Cluster within the DC
When you create the cluster - there's an Import cluster option, if I remember correctly. This should discover the peers and volumes and add it to the engine 3) Create a Domain within the Cluster
4) Add hosts to DC 5) Import Gluster Volume
4 & 5 not required if you change step 2 to import. You are running into errors below because the engine sees the addition of new hosts as gluster peer probing to a new cluster
Some issues. I create a DC, add a Cluster then add the Host to it. Then I try to add another the second node but it says It's already in a cluster. There is no other cluster and the second host is not listed anywhere.

Just upgraded to 4.3.5. What do I do if I can't remove a host from a cluster? Maintenance window options Active and Maintenance are grayed out. Host is currently showing as Unassigned with an exclamation mark next to it. Items listed include: "Power Management is not configured for this Host. Enable Power Management" "Gluster status is disconnected for this host. Restart Glusterd service" "Host has no default route." I try to modify some of this thinking maybe it will nudge the server out of it's slumber but get this when trying to fix Power Management: "Error while executing action: mdskvm-p01.nix.mds.xyz: Cannot edit Host. Host parameters cannot be modified while Host is operational. Please switch Host to Maintenance mode first." Of course I can't put it into maintenance since it's grayed out. Anyway to remove this host and start fresh? Cheers, TK

So I try to remove the first host to restart from the beginning. It says I can't remove the only host now till it's in maintenance. Maintenance is grayed out. I wait a bit guessing there's background processes running and can finally remove to readd.
When I try to redo the operation and get to the step of adding another host, I get:
"Error while executing action: Server mdskvm-p02.nix.mds.xyz <http://mdskvm-p02.nix.mds.xyz> is already part of another cluster."
But I can clearly see it's not there via another oVirt UI window.

System prevents me from removing and restarting the process again with a:

Hey Sahina,
Thanks very much.
I've taken a quick glance and it does mention I need a third host which I don't have.
However, since I wrote, I removed everything. Had to force remove hosts however the gluster setup and data in it stayed (Or so I'm thinking).
I'll read the article more thoroughly however is there a specific procedure for adding existing oVirt gluster volumes back into a cluster?
One additional question. Is the sequence below correct?
1) Create Data Center 2) Create Cluster within the DC
When you create the cluster - there's an Import cluster option, if I remember correctly. This should discover the peers and volumes and add it to the engine
Trying that now. On a side note, the autodiscovery box is hard to edit.
So in the meantime, trying to up the version to take advantage of some new features and ensure Gluster 6 is fully supported. Not having luck with the oVirt UI upgrade at the moment ( Not a self hosted engine. It's on a separate VM. ):

Just upgraded to 4.3.5.
What do I do if I can't remove a host from a cluster? Maintenance window options Active and Maintenance are grayed out. Host is currently showing as Unassigned with an exclamation mark next to it. Items listed include:
"Power Management is not configured for this Host. Enable Power Management" "Gluster status is disconnected for this host. Restart Glusterd service" "Host has no default route."
I try to modify some of this thinking maybe it will nudge the server out of it's slumber but get this when trying to fix Power Management:
"Error while executing action: mdskvm-p01.nix.mds.xyz: Cannot edit Host. Host parameters cannot be modified while Host is operational. Please switch Host to Maintenance mode first."
Of course I can't put it into maintenance since it's grayed out.
Anyway to remove this host and start fresh?
Cheers, TK
Need to update these certs but the host won't be able to refresh them until I can remove the host: 2019-09-25 20:33:44,897-04 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] Unable to process messages General SSLEngine problem 2019-09-25 20:33:44,908-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-81) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM mdskvm-p01.nix.mds.xyz command Get Host Capabilities failed: General SSLEngine problem Is my understanding correct that oVirt will manage VDSM certificates itself including renewing older certificates? It not, what is the latest procedure to update VDSM certificates? Cheers, TK
3) Create a Domain within the Cluster 4) Add hosts to DC 5) Import Gluster Volume
4 & 5 not required if you change step 2 to import. You are running into errors below because the engine sees the addition of new hosts as gluster peer probing to a new cluster
Some issues. I create a DC, add a Cluster then add the Host to it. Then I try to add another the second node but it says It's already in a cluster. There is no other cluster and the second host is not listed anywhere.
So I try to remove the first host to restart from the beginning. It says I can't remove the only host now till it's in maintenance. Maintenance is grayed out. I wait a bit guessing there's background processes running and can finally remove to readd.
When I try to redo the operation and get to the step of adding another host, I get:
