Hello List,
i am using oVirt Engine Version: 3.5.2.1-1.el6.
I would like to remove a node from a GlusterFS Cluster and use it for
local storage.
So i put my node into maintance. Reinstalled it freshly with CentOS7.
Now i would like to add it to a New Cluster with local storage, but i get:
Error while executing action: Cannot add Host. Host with the same UUID
already exists.
How can i resolve this problem?
I can NOT remove my old host from the Gluster: Cannot remove Host.
Server having Gluster volume.
Thanks,
Mario
8:04 a.m.
A log will be nice.
However, can you please compare /etc/vdsm/vdsm.id in both hosts?
If not available at new host it might be a bios issue, try to uuidgen >
/etc/vdsm/vdsm.id and add host.

Hi,
I have resolved this in such way.
On the engine host connect to db:
su postgres
psql -s engine
Then delete host from db manualy:
select vds_id from vds_static where host_name = 'HOST_NAME';
delete from vds_statistics where vds_id = 'id';
delete from vds_dynamic where vds_id = 'id';
delete from vds_static where vds_id = 'id';

Thanks,
i solved it by:
uuidgen > /etc/vdsm/vdsm.id
I was just confused because /etc/vdsm/vdsm.id did not exist at that
point on my new node.
Thanks.

Please compare:
# dmidecode -s system-uuid
At both machines.
If equals then your bios has well known bug, the method to override it is to manually
create /etc/vdsm/vdsm.id

Hi,
I have resolved this in such way.
On the engine host connect to db:
su postgres
psql -s engine
Then delete host from db manualy:
select vds_id from vds_static where host_name = 'HOST_NAME';
delete from vds_statistics where vds_id = 'id';
delete from vds_dynamic where vds_id = 'id';
delete from vds_static where vds_id = 'id';
this is only part of the work, now you have junk in some of your table
The right way is to call
SELECT DeleteVds(<uuid>);
the body of this SP is :
---Start---
UPDATE vm_static
SET dedicated_vm_for_vds = null
WHERE dedicated_vm_for_vds = v_vds_id;
DELETE FROM tags_vds_map
WHERE vds_id = v_vds_id;
-- Delete all Vds Alerts from the database
PERFORM DeleteAuditLogAlertsByVdsID(v_vds_id);
DELETE FROM vds_statistics WHERE vds_id = v_vds_id;
DELETE FROM vds_dynamic WHERE vds_id = v_vds_id;
DELETE FROM vds_static WHERE vds_id = v_vds_id;
DELETE FROM permissions where object_id = v_vds_id;
--- end ---
Please verify that you complete the missing operations manually and consult with us in
future before doing anything directly on the database
Thanks

You could remove all the bricks which are added from old host using
remove bricks action and try removing the host.
