Hi Marcelo, Is it cold (the VM is down) or live (the VM is up) merge (snapshot deletion)? What version are you running? Can you please share engine and vdsm logs? Please note that at some point we try to verify that image was removed by running getVolumeInfo hence, the volume not found is expected. The thing is, that you say that volume does exist. Can you run following command on the host: vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol> Thank you, Ala On Sat, Mar 12, 2016 at 3:35 PM, Marcelo Leandro <marceloltmm@gmail.com> wrote:

You question is not clear. Can you explain what is the unexpected behavior? To check if an lv created or removed by ovirt, you can do: pvscan --cache lvs vg-uuid Nir

What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Please note that at some point we try to verify that image was removed by running getVolumeInfo hence, the volume not found is expected. The thing is, that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>

You question is not clear. Can you explain what is the unexpected behavior?
the link to the lvm should not be deleted after deleting the snapshot?
Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume? /dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of: pvscan --cache lvs vgname ls -l /dev/vgname Both before the the merge, and after the merge was completed. The lv should not exist, and the links should be deleted. Links under /run/vdsm/storage or /rhev/data-center/ should be created when starting a vm, and tore down when stopping a vm, hotunpluging a disk, or removing a snapshot. To understand if there is an issue, we need the output of: tree /run/vdsm/stoage/domain/image tree /rhev/data-center/pool/domain/images/image Before and after the merge. The links should be deleted.

I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?

pvscan --cache lvs vg-uuid
Nir

VM is up
What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Please note that at some point we try to verify that image was removed by running getVolumeInfo hence, the volume not found is expected. The thing
is,
that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>
return the command: [root@srv-qemu03 93633835-d709-4ebb-9317-903e62064c43]# vdsClient -s 0 getVolumeInfo c2dc0101-748e-4a7b-9913-47993eaa52bd 77e24b20-9d21-4952-a089-3c5c592b4e6d 93633835-d709-4ebb-9317-903e62064c43 948d0453-1992-4a3c-81db-21248853a88a Volume does not exist: ('948d0453-1992-4a3c-81db-21248853a88a',)
after restarting the host where vm was on, the link discs in image_group_id was broken but was not removed.

You question is not clear. Can you explain what is the unexpected
behavior?
the link to the lvm should not be deleted after deleting the snapshot?
Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:
pvscan --cache lvs vgname ls -l /dev/vgname
Both before the the merge, and after the merge was completed.
The lv should not exist, and the links should be deleted.
Links under /run/vdsm/storage or /rhev/data-center/ should be created when starting a vm, and tore down when stopping a vm, hotunpluging a disk, or removing a snapshot.
To understand if there is an issue, we need the output of:
tree /run/vdsm/stoage/domain/image tree /rhev/data-center/pool/domain/images/image
Before and after the merge.
The links should be deleted.

Good morning
I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?
You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid

VM is up
What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Please note that at some point we try to verify that image was removed
running getVolumeInfo hence, the volume not found is expected. The
by thing is,
that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>
return the command: [root@srv-qemu03 93633835-d709-4ebb-9317-903e62064c43]# vdsClient -s 0 getVolumeInfo c2dc0101-748e-4a7b-9913-47993eaa52bd 77e24b20-9d21-4952-a089-3c5c592b4e6d 93633835-d709-4ebb-9317-903e62064c43 948d0453-1992-4a3c-81db-21248853a88a Volume does not exist: ('948d0453-1992-4a3c-81db-21248853a88a',)
after restarting the host where vm was on, the link discs in image_group_id was broken but was not removed.

You question is not clear. Can you explain what is the unexpected
behavior?
the link to the lvm should not be deleted after deleting the snapshot?
Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:
pvscan --cache lvs vgname ls -l /dev/vgname
Both before the the merge, and after the merge was completed.
The lv should not exist, and the links should be deleted.
Links under /run/vdsm/storage or /rhev/data-center/ should be created when starting a vm, and tore down when stopping a vm, hotunpluging a disk, or removing a snapshot.
To understand if there is an issue, we need the output of:
tree /run/vdsm/stoage/domain/image tree /rhev/data-center/pool/domain/images/image
Before and after the merge.
The links should be deleted.
Nir

Good morning
I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?
You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid

Right?
Yes, this seems to be a bug when doing a merge on a host which is not the spm. According to the log you attached (vdsm.log.5): - we do not deactivate the lv after the merge - therefore the link /dev/vgname/lvname is not deleted - we don't delete the link at /rhev/data-center - we don't delete the links at /run/vdsm/storage The links under /run/vdsm/storage and /rhev/data-center should will be deleted when hotunpluging this disk, or when stopping the vm. Please file a ovirt/vdsm bug for this and include the information from this thread. Nir

Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
in /rhev/data-center/pull/domain/image/volume
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:

VM is up
What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Please note that at some point we try to verify that image was removed by running getVolumeInfo hence, the volume not found is expected. The thing is, that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>
return the command: [root@srv-qemu03 93633835-d709-4ebb-9317-903e62064c43]# vdsClient -s 0 getVolumeInfo c2dc0101-748e-4a7b-9913-47993eaa52bd 77e24b20-9d21-4952-a089-3c5c592b4e6d 93633835-d709-4ebb-9317-903e62064c43 948d0453-1992-4a3c-81db-21248853a88a Volume does not exist: ('948d0453-1992-4a3c-81db-21248853a88a',)
after restarting the host where vm was on, the link discs in image_group_id was broken but was not removed.

You question is not clear. Can you explain what is the unexpected behavior?
the link to the lvm should not be deleted after deleting the snapshot?
Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:
pvscan --cache lvs vgname ls -l /dev/vgname
Both before the the merge, and after the merge was completed.
The lv should not exist, and the links should be deleted.
Links under /run/vdsm/storage or /rhev/data-center/ should be created when starting a vm, and tore down when stopping a vm, hotunpluging a disk, or removing a snapshot.
To understand if there is an issue, we need the output of:
tree /run/vdsm/stoage/domain/image tree /rhev/data-center/pool/domain/images/image
Before and after the merge.
The links should be deleted.
Nir

Good morning
I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?
You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid

it must have just one disk after the merge.
Right?
Yes, this seems to be a bug when doing a merge on a host which is not the spm.
According to the log you attached (vdsm.log.5): - we do not deactivate the lv after the merge - therefore the link /dev/vgname/lvname is not deleted - we don't delete the link at /rhev/data-center - we don't delete the links at /run/vdsm/storage
The links under /run/vdsm/storage and /rhev/data-center should will be deleted when hotunpluging this disk, or when stopping the vm.
Please file a ovirt/vdsm bug for this and include the information from this thread.

Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
in /rhev/data-center/pull/domain/image/volume
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:

VM is up
What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Please note that at some point we try to verify that image was
removed
by running getVolumeInfo hence, the volume not found is expected. The thing is, that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>
return the command: [root@srv-qemu03 93633835-d709-4ebb-9317-903e62064c43]# vdsClient -s 0 getVolumeInfo c2dc0101-748e-4a7b-9913-47993eaa52bd 77e24b20-9d21-4952-a089-3c5c592b4e6d 93633835-d709-4ebb-9317-903e62064c43 948d0453-1992-4a3c-81db-21248853a88a Volume does not exist: ('948d0453-1992-4a3c-81db-21248853a88a',)
after restarting the host where vm was on, the link discs in image_group_id was broken but was not removed.

You question is not clear. Can you explain what is the unexpected behavior?
the link to the lvm should not be deleted after deleting the
snapshot?
Are you talking about /dev/vgname/lvname link or the links under /run/vdsm/storage/domain/image/volume, or /rhev/data-center/pull/domain/image/volume?
/dev/vgname/lvname is created by udev rules when lv is activated or deactivated. To understand if this is the issue, can you show the output of:
pvscan --cache lvs vgname ls -l /dev/vgname
Both before the the merge, and after the merge was completed.
The lv should not exist, and the links should be deleted.
Links under /run/vdsm/storage or /rhev/data-center/ should be created when starting a vm, and tore down when stopping a vm, hotunpluging a disk, or removing a snapshot.
To understand if there is an issue, we need the output of:
tree /run/vdsm/stoage/domain/image tree /rhev/data-center/pool/domain/images/image
Before and after the merge.
The links should be deleted.
Nir

You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid

VM is up
What version are you running?
oVirt Engine Version: 3.6.3.4-1.el7.centos
Can you please share engine and vdsm logs?
yes.
Looking in your vdsm log, I see this error (454 times in 6 hours), which looks like a bug: periodic/5::ERROR::2016-03-12 09:28:02,847::executor::188::Executor::(_execute_task) Unhandled exception in <NumaInfoMonitor vm=8d41b39a-5995-41a0-9807-7d9a6af308a5 at 0x7f898836f090> Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 186, in _execute_task callable() File "/usr/share/vdsm/virt/periodic.py", line 279, in __call__ self._execute() File "/usr/share/vdsm/virt/periodic.py", line 324, in _execute self._vm.updateNumaInfo() File "/usr/share/vdsm/virt/vm.py", line 5071, in updateNumaInfo self._numaInfo = numaUtils.getVmNumaNodeRuntimeInfo(self) File "/usr/share/vdsm/numaUtils.py", line 116, in getVmNumaNodeRuntimeInfo vnode_index = str(vcpu_to_vnode[vcpu_id]) KeyError: 1 Adding Francesco and Martin to look at this.
Please note that at some point we try to verify that image was removed by running getVolumeInfo hence, the volume not found is expected. The thing is, that you say that volume does exist. Can you run following command on the host:
vdsClient -s 0 getVolumeInfo <sd> <sp> <img> <vol>
return the command: [root@srv-qemu03 93633835-d709-4ebb-9317-903e62064c43]# vdsClient -s 0 getVolumeInfo c2dc0101-748e-4a7b-9913-47993eaa52bd 77e24b20-9d21-4952-a089-3c5c592b4e6d 93633835-d709-4ebb-9317-903e62064c43 948d0453-1992-4a3c-81db-21248853a88a Volume does not exist: ('948d0453-1992-4a3c-81db-21248853a88a',)
after restarting the host where vm was on, the link discs in image_group_id was broken but was not removed.

You question is not clear. Can you explain what is the unexpected behavior?
the link to the lvm should not be deleted after deleting the snapshot?
Thanks

Good morning
I have a doubt, when i do a snapshot, a new lvm is generated, however when I delete this snapshot the lvm not off, that's right?
You question is not clear. Can you explain what is the unexpected behavior?
To check if an lv created or removed by ovirt, you can do:
pvscan --cache lvs vg-uuid
