<![CDATA[image Multicast issue]]>Hi,

i got some issue with Multicast image, had this issue for sometime, now im running the latest 1.5.10.1815 and still got this issue.

If i create a multicast image task , by going to image menu then clicking Multicast image, and creating a multicast session. It works, but then if i want to do an other session , when i click on start, it just reset the fields to default value (session name, count, timeout, image ) but the multicast session is not created.

if i reboot the server i still cannot create a multicast image session anymore.
i noticed that if i run the database maintenance queries :
DELETE FROM hosts WHERE hostID = ‘0’;
DELETE FROM hostMAC WHERE hmID = ‘0’ OR hmHostID = ‘0’;
DELETE FROM groupMembers WHERE gmID = ‘0’ OR gmHostID = ‘0’ OR gmGroupID = ‘0’;
DELETE FROM snapinGroupAssoc WHERE sgaID = ‘0’ OR sgaSnapinID = ‘0’ OR sgaStorageGroupID = ‘0’;
DELETE from snapinAssoc WHERE saID = ‘0’ OR saHostID = ‘0’ OR saSnapinID = ‘0’;
DELETE FROM hosts WHERE hostID NOT IN (SELECT hmHostID FROM hostMAC WHERE hmPrimary = ‘1’);
DELETE FROM hosts WHERE hostID NOT IN (SELECT hmHostID FROM hostMAC);
DELETE FROM hostMAC WHERE hmhostID NOT IN (SELECT hostID FROM hosts);
DELETE FROM snapinAssoc WHERE saHostID NOT IN (SELECT hostID FROM hosts);
DELETE FROM groupMembers WHERE gmHostID NOT IN (SELECT hostID FROM hosts);
DELETE FROM tasks WHERE taskStateID IN (“1”,“2”,“3”);
DELETE FROM snapinTasks WHERE stState in (“1”,“2”,“3”);
TRUNCATE TABLE multicastSessions;
TRUNCATE TABLE multicastSessionsAssoc;
DELETE FROM tasks WHERE taskTypeId=8;

then i can create a task again.

Is there anything to fix this behavior?

I did not update yet to 1824, but i did SELECT * FROM HISTORY;

MariaDB [fog]> SELECT * FROM history;

the new session i create are not shown, and dont work until i run the maintenance queries

then it shows in history table:

MariaDB [fog]> SELECT * FROM history;

Change your branch from stable -> dev-branch

cd /path/to/installer
git checkout dev-branch
git pull
cd bin
sudo ./installfog.sh -y

This will install whatever is “bleeding edge” on the development (which eventually roll up into the stable automatically on the 15th of each month).

It’s not a big issue, i can either multicast by doing a quick registration on my devices , grouping them and doing a group multicast. that works everytime. or just run the queries, and that seem to flush whatever it is that is blocking the multicast.

Thanks!

When I test in 1824, I’m not seeing the problem. So it’s possible a future set of updates fixed the problem you’re specifically looking at.

When a MC task cancels (or completes) the session name is expected to be cleared out because you may need to reuse the session name down the road.

I’m seeing the clients and time are being set correctly.

Maybe I’m not understanding what exactly you’re doing?

Similarly, I started 2 multicast sessions for the exact same image, and I’m unable to replicate what you’re seeing.

i also cancelled one then started a new session and that worked.

To be fair (like I said) I’m on 1824 so maybe we unknowingly fixed the problem you’re hitting right now?
