Really, I don't know how is possible this.

Hi Tibor, I am not sure I completely understand the scenario. You have a VM with two disks and then you create a snapshot including the two disks? Before creating the snapshot, did the VM recognize the two disks? On Mon, Nov 13, 2017 at 10:36 PM, Demeter Tibor <tdemeter@itsmart.hu> wrote:

Because, I didn't import that vm from the storage domain, I did an another similar VM with exactly same sized thin-provisioned disks. I have renamed, copied to here my originals.
The VM started successfully, but the disk that contain a snapshot did not recognized by the os. I can see the whole disk as raw. (disk id, format in ovirt, filenames of images, etc) . I think ovirt don't know that is a snapshotted image and use as raw. Is it possible? I don't see any snapshot in snapshots. Also I have try to list snapshots with qemu-img info and qemu-img snapshot -l , but it does not see any snapshots in the image.
Really, I don't know how is possible this.

Hi Tibor, Can you please explain this part: "After this I just wondered, I will make a new VM with same disk and I will copy the images (really just rename) from original to recreated." What were the exact steps you took? Thanks On Thu, Nov 16, 2017 at 4:19 PM, Demeter Tibor <tdemeter@itsmart.hu> wrote:
Hi,
Thank you for your reply.
So. I have a disk with snapshot. Or - really - I just think that is a snapshot. It was attached originally to a VM (with other two disks, that is not have snapshot) I did a detach-attach-storage procedure, but after attach, - I don't know why - ovirt could not import the VM and disks from this (ovirt said it is not possible). After this I just wondered, I will make a new VM with same disk and I will copy the images (really just rename) from original to recreated.
It was partial success because the VM can boot, but the disk, where there is a snapshot I can't read the LVM table. I see just it seems to corrupt. Now this disk in a very interested state: I can see the snapshot datas from the vm as raw disk. I think Ovirt don't know that is a snapshotted image and attach to VM as raw disk.
So my really question, how can I add this disk image as good to ovirt?
Please help me, it is very important me.:(
Thanks in advance,
Have a nice day,
Tibor

Hi Tibor, I am not sure I completely understand the scenario.
You have a VM with two disks and then you create a snapshot including the two disks? Before creating the snapshot, did the VM recognize the two disks?

My problem is inside VM I see the content as raw disk. I thing Ovirt don't want to use it as a snapshotted image. Or what ?
Demeter, can you share the output of this command on a host running your vm? virsh -r dumpxml vm-name Nir
Thank you.

Hi,

So. I have a disk with snapshot. Or - really - I just think that is a snapshot. It was attached originally to a VM (with other two disks, that is not have snapshot) I did a detach-attach-storage procedure, but after attach, - I don't know why - ovirt could not import the VM and disks from this (ovirt said it is not possible). After this I just wondered, I will make a new VM with same disk and I will copy the images (really just rename) from original to recreated.
It was partial success because the VM can boot, but the disk, where there is a snapshot I can't read the LVM table. I see just it seems to corrupt. Now this disk in a very interested state: I can see the snapshot datas from the vm as raw disk. I think Ovirt don't know that is a snapshotted image and attach to VM as raw disk.
So my really question, how can I add this disk image as good to ovirt?
Please help me, it is very important me.:(
Thanks in advance,
Have a nice day,

Hi Tibor, I am not sure I completely understand the scenario.
You have a VM with two disks and then you create a snapshot including the two disks? Before creating the snapshot, did the VM recognize the two disks?

Dear Users,
I have a disk of a vm, that is have a snapshot. It is very interesting, because there are two other disk of that VM, but there are no snapshots of them.

Because, I didn't import that vm from the storage domain, I did an another similar VM with exactly same sized thin-provisioned disks. I have renamed, copied to here my originals.
The VM started successfully, but the disk that contain a snapshot did not recognized by the os. I can see the whole disk as raw. (disk id, format in ovirt, filenames of images, etc) .

Really, I don't know how is possible this.

Demeter, can you share the output of this command on a host running your vm?

Hi,
Thank you for your reply.
So. I have a disk with snapshot. Or - really - I just think that is a snapshot. It was attached originally to a VM (with other two disks, that is not have snapshot) I did a detach-attach-storage procedure, but after attach, - I don't know why - ovirt could not import the VM and disks from this (ovirt said it is not possible). After this I just wondered, I will make a new VM with same disk and I will copy the images (really just rename) from original to recreated.
It was partial success because the VM can boot, but the disk, where there is a snapshot I can't read the LVM table. I see just it seems to corrupt. Now this disk in a very interested state: I can see the snapshot datas from the vm as raw disk. I think Ovirt don't know that is a snapshotted image and attach to VM as raw disk.
So my really question, how can I add this disk image as good to ovirt?
Please help me, it is very important me.:(
Thanks in advance,
Have a nice day,
Tibor

Hi Tibor, I am not sure I completely understand the scenario.
You have a VM with two disks and then you create a snapshot including the two disks? Before creating the snapshot, did the VM recognize the two disks?

Dear Users,
I have a disk of a vm, that is have a snapshot. It is very interesting, because there are two other disk of that VM, but there are no snapshots of them. I found this while I've try to migrate a storage-domain between two datacenter. Because, I didn't import that vm from the storage domain, I did an another similar VM with exactly same sized thin-provisioned disks. I have renamed, copied to here my originals.
The VM started successfully, but the disk that contain a snapshot did not recognized by the os. I can see the whole disk as raw. (disk id, format in ovirt, filenames of images, etc) . I think ovirt don't know that is a snapshotted image and use as raw. Is it possible? I don't see any snapshot in snapshots. Also I have try to list snapshots with qemu-img info and qemu-img snapshot -l , but it does not see any snapshots in the image.
Really, I don't know how is possible this.

Because it is a very big (13 TB) disk I can't migrate to an another image, because I don't have enough free space. So I just would like to use it in ovirt like in the past.
I have a very old ovirt (3.5)
How can I use this disk?
Thanks in advance,
Regards,
Tibor
