Hello,
I have env1 and env2, both in 4.3 and both configured as single host HCI
environments.
On both I have the predefined hosted_storage, data and vmstore gluster
storage domains.
On env1 I have hosted_storage and data on a disk, and vmstore on a whole
different disk. I also have a "big2" gluster storage domain created in
another disk in a second time.
I want to scratch env1 but preserve and then import vmstore and big2
storage domains in env2
This "big2" is configured as a PV on the whole 4Tb disk on env1.

In similar way the vmstore storage domain has:

I presume the correct way is:
- env1
delete and detach vmstore and big2 (without formatting/zeroing)
- env2
attach the two disks to the system
and then?
What should I do at gluster commands level to "import" the already setup
gluster bricks/volumes and then at oVirt side to import the corresponding
storage domain?
BTW: can I import the previous storage domain named "vmstore" giving anothe
r name such as vmstore2, not to create conflict with already existing
"vmstore" storage domain or the name is hard coded when importing and
creating possible conflict?
Thanks,
Gianluca
