Hi,

I believe that when you replicate the LUN using Array Storage, you also replicate the uuid of the lvm (volume group) that oVirt/Linux uses.
I believe this is the cause of not being able to import the new LUN as Domain Storage.
You can view the logs on the host you chose to import the LUN (rescan process). The file is located in /var/log/vdsm/vdsm.log.

My suggestion:
1 - Create a new LUN
2 - Create a Domain Storage
3 - Replicate the data (disks) using some script or backup software such as Vinchin

Cheers!

Hi All,

We wish to create some kind of DR plan for our OVM 4.4.10.7-1.0.22.el8 environment.

Idea is to do storage replication of defined Storage Domains.

steps:

create LUN on storage
present LUN to OVM
create Storage Domain
put VMs on Storage Domain
on storage

replicate LUN to another storage [or the same storage]
Storage Domains contains OVF_STORE

Now, recovery

On live OVM

present replica of LUN
import Storage Domain
But we cannot import replica LUN. Where to look for errors? Is this action possible it all?

Facts

OVM is the same version
Storage is the same vendor
LUN is browsable on SAN level and have differen WWIN, if we wish to add replicated LUN like new Storage Domain. Adding new Storage Domain mean that LUN will be formatted ...
What I do wrong?
