Hi,

I don't mean on the fly upgrade, just confused that i should stop all
VMs at once, as i understood procedure. If it's possible to do per VM,
it's perfectly OK for me.

Thank you Nir for clarification.

Best regards,
Misak Khachatryan

You can enable it per vm, you don't need to stop all of them. But I think
we do not support upgrading a machine with running vms, so upgrading
requires:

1. migrating vms from the host you want to upgrade
2. upgrading the host
3. stopping the vm you want to upgrade to libgfapi
4. starting this vm on the upgraded host

Theoretically qemu could switch from one disk to another, but I'm not
sure this is supported when switching to the same disk using different
transports. I know it is not supported now to mirror a network drive to
another network drive.

The old disk is using:







The new disk should use:










Adding qemu-block mailing list.

2017-11-15 Thread Kasturi Narra

Hi Misak,

  I do not think we will be supporting any in the near future. Enabling
gfapi means that access mechanism of drive changes and i think we will need
to stop the vms.

Thanks

Hi Bryan,

 In your output if you see the -drive file=gluster:/// 
this means that vm disk drives are being accessed using libgfapi. 

If it is fuse then you would have seen something like 
"file=/rhev/data-center/59f2df7e-0388-00ea-02c2-017b/67d7d3cc-df3f-4d07-b6f3-944982c5677c/images/8e6f96d3-2ed4-4c56-87d1-3a994284e683/9bf5a54e-d72d-4b1f-8ab1-0a84eb987fdd"

restarted the engine, shutdown the vm completely and started it back up a

I am using this command to check:

Hi again,
OK, tried to stop all the vms, except the engine, set engine-config -s 
LibgfApiSupported=true (for 4.2 only) and restarted the engine.
When I tried restarting the VMs they are still not using gfapi, so it does 
not seem to help.

The only command I tried was engine-config -s LibgfApiSupported=true but the 
result is what is shown in my output below, so it’s set to true for v4.2. 
Is it enough?
I’ll try restarting the engine. Is it really needed to stop all the VMs 
and restart them all? Of course this is a test setup and I can do it, but 
for production clusters in the future it may be a problem.

The procedure to enable gfapi is below.

Hi,

I'm using the latest 4.2 beta release and want to try the gfapi access, but 
I'm currently failing to use it.

My test setup has an external glusterfs cluster v3.12, not managed by oVirt.

The compatibility flag is correctly showing gfapi should be enabled with 
4.2:

# engine-config -g LibgfApiSupported
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: false version: 4.1
LibgfApiSupported: true version: 4.2

The data center and cluster have the 4.2 compatibility flags as well.

However, when starting a VM with a disk on gluster I can still see the disk 
is mounted via fuse.

Any clue of what I'm still missing?

Re: [ovirt-users] Enabling libgfapi disk access with oVirt 4.2

2017-11-14 Thread Bryan Sockel

Hrm, not sure what i am doing wrong then, does not seem to be working for 
me.  I am not using the hosted engine, but a direct install on a physical 
server.  I thought i have enabled support for libgfapi with this command:

# engine-config -g LibgfApiSupported
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: true version: 4.1

restarted the engine, shutdown the vm completely and started it back up a 
short time later.

I am using this command to check:
 ps ax | grep qemu | grep 'file=gluster\|file=/rhev'

Output is 
 file=gluster://10.20.102.181/gl-vm12/

Thanks
Bryan

You do need to stop the VMs and restart them, not just issue a reboot. I havn’t 
tried under 4.2 yet, but it works in 4.1.6 that way for me.

[ovirt-users] Enabling libgfapi disk access with oVirt 4.2

2017-11-08 Thread Alessandro De Salvo


Hi,

I'm using the latest 4.2 beta release and want to try the gfapi access, 
but I'm currently failing to use it.


My test setup has an external glusterfs cluster v3.12, not managed by oVirt.

The compatibility flag is correctly showing gfapi should be enabled with 
4.2:


# engine-config -g LibgfApiSupported
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: false version: 4.1
LibgfApiSupported: true version: 4.2

The data center and cluster have the 4.2 compatibility flags as well.

However, when starting a VM with a disk on gluster I can still see the 
disk is mounted via fuse.


Any clue of what I'm still missing?

Thanks,


   Alessandro
