Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

Thanks for your answer, but I have just decided to reinstall everything from 
scratch, because I don't want to spend too much time on this testing 
environment.

Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

Ok, after updating the DB, it is now fine:
# update storage_server_connections set connection='' where 
id='';

But (because there is always a 'but'), I still have an issue when I reboot host 
where Hosted VM runs, I have to do a:
# hosted-engine --clean-metadata
In order to have Hosted VM starts.
Else, the error I have is:
sanlock[1268]: 2016-06-03 11:45:15+ 5973 [1273]: r3 cmd_acquire 2,8,3274 
invalid lockspace found -1 failed 0 name ab7ce50d-238a-4f4f-a36e-8d06e276ae4b
libvirtd[2586]: Failed to acquire lock: No space left on device

Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I have tried these steps :

-  Stop Hosted VM

-  # vdsClient -s localhost forcedDetachStorageDomain 

-  Domain is now detached

-  # hosted-storage –clean-metadata

-  # hosted-storage –vm-start

But, hosted domain path is still the old one.
If I run :
# vdsClient -s localhost getStorageDomainsList 
The path is correct !!

So I don’t know where the wrong path is stored.

I think the only way is to reinstall Hosted VM from scratch.

@ Staniforth Paul, your procedure is not working ☹

You must create a situation where vdsm would fail to monitor that domain. I.e 
stop sharing that path or block it and then the status will allow you to force 
remove

Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I am not able to do that, "Remove" button is greyed.
And it is not possible to place it into maintenance mode because hosted VM is 
running on it...

Any clue?

Thanks.

Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I have followed these steps :


-  Stop supervdsmd + vdsmd + ovirt-ha-agent + ovirt-ha-broker

-  Modify config file

-  Copy files (cp better handles sparse files than rsync)

-  Umount old hosted-engine path

-  Restart services

-  Hosted VM doesn't start => hosted-engine -clean-metadata. I get an 
error at the end, but now I am able to start Hosted VM :

o   ERROR:ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:Metadata for 
current host missing.

I can connect to oVirt interface, everything seems to be working fine, but the 
Hosted storage domain has an incorrect path, it is still pointing to old one... 
I think this information is not correctly reported by web interface, because 
this path doesn't exist anymore, and hosted VM is working !
Does anyone knows how to fix that ?

Lionel BEARD

Hi,

I'm trying to move Hosted storage from one NFS server to another.
As this is not a production environment, so I gave a try with no success, with 
a plan similar to yours.

But I don't like to stay on a failure, so I will give a second chance by 
following your plan :)

Objet : [ovirt-users] Moving Hosted Engine NFS storage domain


Hello,

 we would like to move our NFS storage used for the HostedEngine.



Plan would be

  *   enable global maintenance
  *   shut-down HostedEngine VM
  *   edit  /etc/ovirt-hosted-engine/hosted-engine.conf on hosts

 *   storage=newnfs:/newnfsvolume

  *   copy storage domain from old to new nfs server
  *   start HostedEngine VM
  *   run engine-setup on HostedEngine VM
  *   disable global maintenance

Has anyone had any experience doing this?

Have I missed any steps out

we are currently running oVirt 3.6.2



Thanks,

  Paul S.

Re: [ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I'm trying to move Hosted storage from one NFS server to another.
As this is not a production environment, so I gave a try with no success, with 
a plan similar to yours.

But I don't like to stay on a failure, so I will give a second chance by 
following your plan :)

Regards,
Lionel BEARD

[ovirt-users] Hosted-Engine storage migration

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I would like to migrate Hosted Engin VM from a NFS storage domain to another 
NFS one.
I have tried to move data and to update HostedEngine.conf and vm.conf but with

Is there a procedure to perform this operation ?

Thanks !
