Bug Description

I enlisted 14 nodes, by powering them up manually and watching them appear in maas. I selected all and chose enlist.

Maas took over, enlisted, and they were powered down at the end. So far, so good.

I then selected all of them and chose "commission".

Maas powered them up and ran the commissioning scripts. In the end, the machines were "Ready", but several had "error" in the power state. See attached screenshot.

The logs were also suddenly full with messages like:

That's very unsettling, because these machines were *just* commissioned by maas itself, using the ipmi credentials that maas created.

I then clicked on one of the problematic nodes and hit the "check power state" button. To my surprise, it worked and said the machine was off, as it should be. Going back to the node list, the power status was correct and the error condition was reset.

Turns out after a while, all of them were good again.

This bug is about that ERROR state that happened right after commissioning. I can understand the power status in the web ui being a bit delayed, but the password was never incorrect, so I don't understand where the ERROR state came from.

The error state came from the fact that commissioning changes the IPMI password to the BMC. Power monitoring works by the cluster asking the region for all of its nodes and its power information, it then goes through the list of returned nodes updating each one by one. The list will contain an invalid power password for ipmi once commissioning has changed it, so on next request from the cluster to the region asking for the nodes and power information it will get the new password and it will succeed.

This would be a hard fix, I think the best thing to do would be to only update the BMC password on enlistment and not on commissioning, but that has been in debate for a while.

Hi Ed,

If you are being affected by this issue in 2.0, can you provide logs?

1. cloud-init logs from the commissioning environment itself
2. /var/log/maas/rsyslog/<machine-name>/.../messages.

Thanks.

Hi Ed,

I found the same thing with HP ILO [IPMI 2] but then I realized that the username and password which is auto completed by maas during the commissioning is not the username and password supplied by me in the ILO setup.

The commissioning is a kind of smoke test and I dont think it is able to obtain the details of the ilo user/password. Therefore it auto completes the smoke test with the default user/randompass.
I've done this a number of times and the result is the same.

After I changed the values in MAAS to the correct values I supplied in ilo it works. Of course, if I do a commission on the host, then the correct ilo values must be supplied again together with the power mac.

Fortunately you only need to run the commission once.
