Dear All,
Are there tools to remove this task (in attach) ?
taskcleaner.sh it's seems doens't work:
[root at ovirt-new dbutils]# ./taskcleaner.sh -v -r
select exists (select * from information_schema.tables where
table_schema = 'public' and table_name = 'command_entities');
t
SELECT DeleteAllCommands();
6
[root at ovirt-new dbutils]# ./taskcleaner.sh -v -R
select exists (select * from information_schema.tables where
table_schema = 'public' and table_name = 'command_entities');
t
This will remove all async_tasks table content!!!
Caution, this operation should be used with care. Please contact support
prior to running this command
Are you sure you want to proceed? [y/n]
y
TRUNCATE TABLE async_tasks cascade;
TRUNCATE TABLE
after that I see the same running tasks . Does It make sense ?
Thanks
Best Regards
Enrico
