Hi,

https://pastebin.com/raw/cFrphHHh

The problematic disk is

  <disk type='file' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
      <source file='/rhev/data-center/bcc17ec5-3ba3-4664-ba47-24fde9d92a2a/d2f65815-5f25-4740-ba56-76749a0f4571/images/d1db6e0e-87d0-4124-8326-b18bff3fdf90/5974fd33-af4c-4e3b-aadb-bece6054eb6b'>
        <seclabel model='selinux' relabel='no'/>
      </source>
      <target dev='vdc' bus='virtio'/>
      <serial>d1db6e0e-87d0-4124-8326-b18bff3fdf90</serial>

      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </disk>

What can I do?

Thank you for your time!

Hi,

Sorry for my bad English:(

Ovirt could not import my VM and disks from original storge-domain. It is an NFS share on a server. 

Then I create an another NFS share on same storage and attached to ovirt as new storgae domain.

At this step I've created a new VM on new storage-domain with same disks. (three think provisioned, 100GB, 60GB and 13TB disks). It was necessary, because ovirt cant import my original disks and VM from the re-attached storage domain. 

Finally I renamed my old disks from old storage domain to new on new storgae domain (it was possible because are there on same file system on nfs server)

At this moment only two virtual disk working fine. The 100 and 60GB disks does working fine, but the 13TB is not. It has a snapshot. Or not? Is it a snapshot or not? 

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 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

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.

qemu-img snapshot -l 5974fd33-af4c-4e3b-aadb-bece6054eb6b

(nothing)

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
