Hi,
I have oVirt setup, separate PC host engine + 2 nodes (#10 + #11) with =
local storage domains (internal RAIDs).
1st node #10 is currently active and can=E2=80=99t be turned off.
Since oVirt doesn=E2=80=99t support more then 1 host in data center with =
local storage domain as described here:
http://lists.ovirt.org/pipermail/users/2018-January/086118.html =
<http://lists.ovirt.org/pipermail/users/2018-January/086118.html>
defined another data center with 1 node #11.
Problem:=20
1) can=E2=80=99t copy or move VM disks from node #10 (even of inactive =
VMs) to node #11, this node is NOT being shown as possible destination.
2) can=E2=80=99t migrate active VMs to node #11.
3) Added NFS shares to data center #1 -> node #10, but can=E2=80=99t =
change data center #1 -> storage type to Shared, because this operation =
requires detachment of local storage domains, which is not possible, =
several VMs are active and can=E2=80=99t be stopped.
VM disks placed on local storage domains because of performance =
limitations of our 1Gbit network.=20
2 VMs running our accounting/inventory control system, and are critical =
to NFS storage performance limits.
How to solve this problem ?
Thanks in advance.
Andrei

Hi,
Which version are you using?
in 4.1 , the support of adding shared storage to local DC was added [1].
You can copy/move disks to the shared storage domain, then detach the SD
and attach to another DC.
In any case, you wont be able to live migrate VMs from the local DC, it is
not supported.
Regards,
Fred

Hi,
Thanks for clarification. I=E2=80=99m using 4.2.
Anyway, I have to define another data center with shared storage domain =
(since data center with local storage domain can have only 1 host), and =
the do what you have described.
Is it possible to copy VM disks from 1 data center #1 local storage =
domain to another data center #2 NFS storage domain, or need to use =
export storage domain ?

Hi,
Just to make clear what you want to achieve:
- DC1 - local storage - host1 - VMs
- DC2 - local storage - host2
You want to move the VMs from DC1 to DC2.
What you can do:
- Add a shared storage domain to the DC#1
- Move VM disk from local SD to shared storage domain
- Put shared storage domain to maintenance
- Detach shared storage from DC1
- Attach shared storage to DC2
- Activate shared storage
- You should be able to register the VM from the shared storage into the DC2
- If you want/need move disks from shared storage to local storage in DC2
Please test this flow with a dummy VM before doing on important VMs.
Regards,
Freddy

Hi,
Just to make clear what you want to achieve:
- DC1 - local storage - host1 - VMs
- DC2 - local storage - host2
You want to move the VMs from DC1 to DC2.
Yes, thanks, this is exactly what I want to accomplish.
BTW, are export domains from different data centers visible to each other=
?
If not, wouldn't be simpler to export VM#1 in DC #1 to Export domain #1,
copy over ssh to DC #2 Export domain, and finally import it into DC #2.
PS. I can't test right now myself, sitting home on sick leave..
What you can do:
- Add a shared storage domain to the DC#1
- Move VM disk from local SD to shared storage domain
- Put shared storage domain to maintenance
- Detach shared storage from DC1
- Attach shared storage to DC2
- Activate shared storage
- You should be able to register the VM from the shared storage into
the DC2
- If you want/need move disks from shared storage to local storage in D=
C2
Please test this flow with a dummy VM before doing on important VMs.
Regards,
Freddy

Hi,
Thanks for clarification. I=E2=80=99m using 4.2.
Anyway, I have to define another data center with shared storage
domain (since data center with local storage domain can have only
1 host), and the do what you have described.
Is it possible to copy VM disks from 1 data center #1 local
storage domain to another data center #2 NFS storage domain, or
need to use export storage domain ?

Using Export domain should work also, but I would go the way I described
earlier.
