Hi Nir,

  I identified the reason for the failing OVF updates on the initial VG – 
metadata was affected by blkdiscard tests in scope of 
https://bugzilla.redhat.com/show_bug.cgi?id=1562369

However, the OVF updates are failing on other installations as well (on 2 out 
of 40 storage domains). Here is the output of your commands:

I worked around the SPM problem by running engine-setup (neither vds-client 
Host/StoragePool *Task*, async_task_entries or taskcleaner.sh showed any tasks).

All the best,

Hi all,

  does anybody have an idea how to address this? There is also a side effect 
that I cannot change SPM (“Error while executing action: Cannot force select 
SPM. The Storage Pool has running tasks.“).

Betreff: Failed to update VMs/Templates OVF data

Hi,

  I have a FC storage domain reporting the following messages every hour:

VDSM command SetVolumeDescriptionVDS failed: Could not acquire resource. 
Probably resource factory threw an exception.: ()
Failed to update OVF disks cb04b55c-10fb-46fe-b9de-3c133a94e6a5, OVF data isn't 
updated on those OVF stores (Data Center VMTEST, Storage Domain VMHOST_LUN_62).
Failed to update VMs/Templates OVF data for Storage Domain VMHOST_LUN_62 in 
Data Center VMTEST.

Trying to manually update OVF results in “Error while executing action

MetaDataKeyNotFoundError: Meta Data key not found error: ("Missing metadata

This means the volume metadata is missing a required key: "DOMAIN".

Can you share the output of:

lvs -o vg_name,lv_name,tags | grep a1e7554d-530c-4c07-a4b5-459a1c509e39

There should a tag named MD_N - N is an integer. Once you find it,
we would like to see the metadata at offset N * 512 in the metadata volume.

You can extract it like this:

dd if=/dev/vgname/metadata bs=512 skip=N
