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

      Hah. Wow. 
Thanks for your patience on this. lol.

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.

engine=# SELECT command_id, disk_id, last_updated, message, timeout_policy, type, active FROM image_transfers;              command_id              |               disk_id                |        last_updated        |        message        | timeout_policy | type | active

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

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"

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?

Would this be found in the "image_transfers" table?
...

\dt shows me that there are 156 tables in the engine database.
And I see an image_transfers table. But it looks empty, like a lot of other tables.

This seems strange to me. All of these tables are empty, unless I'm doing something wrong (I'm new to Postgres).
