Hi Ahmad,

I did the following:

1. Storage -> Storage Domains

2 Click the existing Storage Domain and click "Manage Domain"

and then I see next to the LUN which is already part of the SD the "Add" button

I do not want to click add since it may destroy the existing SD or the content of the LUNs.

In the Engine Log I see the following:
020-07-14 09:57:45,131+02 WARN  [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-20) [277145f2] EVENT_ID: STORAGE_DOMAINS_COULD_NOT_BE_SYNCED(1,046), Storage domains with IDs [6b82f31b-fa2a-406b-832d-64d9666e1bcc] could not be synchronized.

Thanks a lot

Hi Arsène Gschwind,

it's really strange that you see "Add" on a LUN that already has been added to the database.

to verify the steps you did make at first,

1- Storage -> Storage Domains

2- New Domain - [ select iSCSI ]

3- click on "+" on the iscsi target, then you see the "Add" button is available

4- after clicking add and ok, then this error will be shown in the logs

is that right?

can you also attach vdsm log?

Hello all,

I've checked all my multipath configuration and everything seems korrekt.

Is there a way to correct this, may be in the DB?

I really need some help, thanks a lot.

HI,

I'm having a strange behavior with a SD. When trying to manage the SD I see they "Add" button for the LUN which should already be the one use for that SD.

In the Logs I see the following:

It looks like the engine will add a LUN to an SD and it already exist...

Any Idea how to resolve that problem?

Thanks a lot
