[ovirt-users] Re: Unable to put host in maintenance mode & unable to login to Postgres

21 Oct 2021

      Ok, I was able to login to ovirt-engine/api/imagetransfers, and I see the 3 image transfers in here.
Thanks for the help on that.

Based on the example that I'm pasting below, and based on your last email, I tried to run the following curl command:
$ curl -u admin@password -X POST https://ovirt-engine.mydomain.com/ovirt-engine/api/imagetransfers/2bf042e8-7... -k

That produced zero output, and when I refresh the imagetransfers xml file, the image is still there... so I'm not sure if it's doing anything. 

Here's an example from apti/imagetransfers:
<image_transfer href="/ovirt-engine/api/imagetransfers/2bf042e8-7ddd-4f43-a2b1-4a16de5c750a" id="2bf042e8-7ddd-4f43-a2b1-4a16de5c750a">

There they are! 
I just cross-checked these disk_id's, and can confirm these are the 3 that continue to show up in the oVirt UI.

Is it safe for me to simply run DELETE FROM image_transfers; ?

...
It will be better to try to finalize the transfers first - 

...
POST path_to_your_engine/api/imagetransfers/<transfer-id>/finalize

Hi David, 
...
...

Since you tried first to execute the query without semicolon the second attempt to run the query with the semicolon failed.It considers both lines as one query.
...
...
...
Try only - SELECT * FROM image_transfers;
...
...

I tried that, but whenever I use semicolons, I get a syntax error. Here's my full stdout with and without the semicolon: 
...
...
...
...
postgres=# \c engine
You are now connected to database "engine" as user "postgres".
engine=# SELECT * FROM image_transfers
engine-# SELECT * FROM image_transfers;
ERROR:  syntax error at or near "SELECT"
LINE 2: SELECT * FROM image_transfers;

You are missing ';' at the end of the query.
...
...
...

That's why you see no output.

Thank you.
However, that was one of the queries I already tried.
...
...
...
...
...
...
All of the queries I listed in my previous email returned empty results, which is why I was confused. Given the name of some of these tables, I expect to see some data in them.
I just tried re-running that query, making sure to capitalize the "FROM" just in case, but got the same results:
...
...
...
...
...
...
engine=# SELECT * FROM image_transfers
engine-#
...
...
...
...
...
...
I then went into the UI, and migrated a VM from 1 host to another.
During the migration, I re-ran that query, and it still came back empty.
...
...
...
...
...
...
Does this table store information about moving a disk from 1 volume to another, or moving VMs from 1 host to another?
