What I did when my engine was reinstalled

- Via CLI/bash : copy old VM data to new folder (/local/folder/storage/original_vm)
- CLI : check datastore for folders in /rhev/DC/storage
- GUI : create new VM with 512Gb thin provisioned disk
- CLI : check datastore and remember new created disk UUID (can also see this in GUI)
- CLI/bash : copy old disk from /local/folder/storage/original_vm to /rhev/dc/storage/UUID
- GUI : boot VM

regards
Raymond

Hi

Can you take a look at your storage and try to find the disk there.
It seems that they got lost and the engine cant find them.
If you can find them its possible to tie them back (the data seats on the disks)
Just search for those big qcow2 files or ovf ones.

Hi community!
I have instance with 3 nodes: 2 nodes as hypervisors and 1 node as
engine. Data domain is FC array.
The node with engine was fail to boot. After it i have made a fresh
install of the engine. And import a data domain. But only 1 VM was
restored. Another 2 VMs have no disks.
What i can do to restore the VMs?

Hi

You mean you used the disks from FC directly in the VM's and not as NFS share and stored the disk on that NFS share ?

Hi Tolik!
My storage is a FC array. This array have 12 disks with 1 volume
identified by LUN ID. I think this volume on the RAW format. Can i
mount this like NFS?

Hi

I am not very familiar with FC arrays.
But can you try to fsck them somehow ?
The logs show that it cant connect to those disks.
One reason can be that they was not unmounted correctly from the VMs.

After that you can try to import them again into the engine.

Yes exactly. I've create a Vdisk by HP manage utility. And create a
new DATA_DOMAIN with type DATA / Fibre Channel.

if the DC was 3.5, you could just re-install the engine and import the
data domain.
