Problems with restoring VM

Created: 31 Jul 2013 | 11 comments

Hello!

I've a problem in restoring full VM.

I Use Restore from virtual machine backup, using SAN then NBD.

In restore wizzard I choose original location, Restore BIOS UUID, Overwrite existing VM and remove backing information for DVD/CDROM. All prerecovery check pass successfully.

In vCenter console I can see that netbackup creates my VM and try to restore it, but fails

There is some information in log:

Could you please check whether all the Data stores are available online and have enough disk space to recover the data.

Please try to restore the data to different Data store by manual change Data store option in the VM ware recovery option.

Also check if the service account your using in credentials for vCenters or ESX hosts have restore permissions in vCenter

They are online and have enough free space

Please try to restore the data to different Data store by manual change Data store option in the VM ware recovery option.

When I restore to another datastore, it's ok!

Thanks! But I don't understand why it fails with original datastore with nbd transfer? What do I need to check?

Also check if the service account your using in credentials for vCenters or ESX hosts have restore permissions in vCenter

Account has full permissions

Sorry for delay,

Could you please request your VM team to perform health check on the original Data Store?

Hello,

Could you please confirm or share the details whether issue has been resolved or not?

By the sounds of it, a VMDK is being restored.

Are all storage LUNS presented to your backup host. If you are restoring by SAN the presented LUNs need to be online.

Also check if the service account your using in credentials for vCenters or ESX hosts have restore permissions in vCenter.

Don't use SAN to restore... use NBD. NBU might not have access to write to the Datastore (only read).
