Enabling libgfapi disk access with oVirt 4.2
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
Hi , The procedure to enable gfapi is below. 1) stop all the vms running 2) Enable gfapi via UI or using engine-config command 3) Restart ovirt-engine service 4) start the vms. Hope you have not missed any !! Thanks kasturi On Wed, Nov 8, 2017 at 11:58 PM, Alessandro De Salvo < Alessandro.DeSalvo@roma1.infn.it> wrote:

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.

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 kasturi On Wed, Nov 15, 2017 at 12:27 PM, Misak Khachatryan <kmisak@gmail.com> wrote:

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: <disk device="disk" snapshot="no" type="file"> <source file="/rhev/data-center/mnt/server:_volname/sd_id/images/img_id/vol_id"/> <target bus="virtio" dev="vda"/> <driver cache="none" error_policy="stop" io="threads" name="qemu" type="raw"/> </disk> The new disk should use: <disk device="disk" snapshot="no" type="network"> <source name="volname/sd_id/images/img_id/vol_id" protocol="gluster"> <host name="1.2.3.4" port="0" transport="tcp"/> </source> <driver cache="none" error_policy="stop" io="threads" name="qemu" type="raw"/> </disk> Adding qemu-block mailing list.

I don't think this is possible yet, but we're relatively close to actually allowing this. No promises as to when qemu will allow QMP to make arbitrary changes to the block graph, but it is being worked on. Kevin

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/....

Hi Bryan, In your output if you see the -drive file=gluster://<ip>/<vol_name> 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-02c2-00000000017b/67d7d3cc-df3f-4d07-b6f3-944982c5677c/images/8e6f96d3-2ed4-4c56-87d1-3a994284e683/9bf5a54e-d72d-4b1f-8ab1-0a84eb987fdd" Thanks kasturi On Tue, Nov 14, 2017 at 8:37 PM, Bryan Sockel <Bryan.Sockel@altn.com> wrote:
