I've followed guidance in all of the posts here attempting to get Rest to work correctly and still not successful. I've created the role & account on my clusters, I think I've modified all the appropriate yaml files. How can I continue to troubleshoot? NAbox 4.0.10 / Harvest 25.02.0

Hi Lorne, sorry that you've hit a snag. What do you have in the collectors section of the poller in question in your /etc/nabox/harvest/harvest.yml file?

spiral hedge Mar 27, 2025, 6:25 PM

#

Should I add the others? Also note that I just setup this NAbox instance and just completed the migration of data from NAbox3 to NAbox4. I was also never able to get Rest working in NAbox3.

What version of ONTAP is running on your clusters? In Nabox, what do you have selected in edit

#

spiral hedge Mar 27, 2025, 6:33 PM

#

9.15.1p3. Auto is currently selected. If I select Rest, will it still use Zapi where needed?

elfin condor Mar 27, 2025, 6:35 PM

#

I'm not sure, but we can check. Select Rest, click Modify and then let's check the /etc/nabox/harvest/harvest.yml again. I assume it will look similar to what I pasted about

#

Getting this...

elfin condor Mar 27, 2025, 6:39 PM

#

let' see what @edgy harbor says about why Nabox is failing there. In the meantime, you can edit /etc/nabox/harvest/harvest.yml to have

        - Rest
        - RestPerf
        - Zapi
        - ZapiPerf
        - Ems

#

after making that change, restart the container via dc restart havrest, wait a couple of minutes and then run docker logs havrest --since 5m 2>&1 | grep NFSClients

spiral hedge Mar 27, 2025, 6:52 PM

#

Waited at least 10 minutes after the restart and the "docker" command produces nothing.

elfin condor Mar 27, 2025, 6:53 PM

#

well phooey - can you grab a support bundle and upload it to https://upload.nabox.org/nuyo-zuxu-mynu

spiral hedge Mar 27, 2025, 6:56 PM

#

Support bundle has been uploaded

elfin condor Mar 27, 2025, 6:56 PM

#

thanks, looking

#

One quick note. I am now getting Rest data in the FSA dashboard, but nothing in the NFS Clients dashboard

elfin condor Mar 27, 2025, 7:01 PM

#

thanks, that's good to know, progress! I assume you didn't see data in the FSA dashboard before?

spiral hedge Mar 27, 2025, 7:02 PM

#

Correct

elfin condor Mar 27, 2025, 7:02 PM

#

ok good

#

try changing your etc/nabox/harvest/user/rest/custom.yaml to this:

objects:
    NFSClients: nfs_clients.yaml
    Volume: custom_volume_flexgroup.yaml

After making that change, restart the container via dc restart havrest, wait a couple of minutes and then run docker logs havrest --since 5m 2>&1 | grep NFSClients

spiral hedge Mar 27, 2025, 7:14 PM

#

Still not getting anything back from the "docker" command. Where and what should be in the nfs_clients.yaml file?

elfin condor Mar 27, 2025, 7:16 PM

#

the custom.yaml is enabling the out-of-the-box nfs_clients.yaml template that you should see in /data/packages/harvest/conf/rest/9.7.0/nfs_clients.yaml

spiral hedge Mar 27, 2025, 7:18 PM

#

10-4. I do see the file in that location

elfin condor Mar 27, 2025, 7:19 PM

#

can you grab another support bundle and upload so I can take a look at the logs files after the custom.yaml change?

spiral hedge Mar 27, 2025, 7:22 PM

#

Done

elfin condor Mar 27, 2025, 7:22 PM

#

thank you

#

while I dig through the logs, change your etc/nabox/harvest/user/rest/custom.yaml to only this. In other words delete the collector: line.

objects:
    NFSClients: nfs_clients.yaml
    Volume: custom_volume_flexgroup.yaml

Save and do the restart dance

spiral hedge Mar 27, 2025, 7:32 PM

#

Done.
And still nothing from the "docker logs" command

elfin condor Mar 27, 2025, 7:33 PM

#

ok does this return anything? docker logs havrest --since 10m 2>&1 | grep 'unable to merge config'

spiral hedge Mar 27, 2025, 7:34 PM

#

time=2025-03-27T19:28:29.598Z level=ERROR source=havrest.go:49 msg="unable to merge config" error="yaml: unmarshal errors:\n line 4: cannot unmarshal !!seq into string"

elfin condor Mar 27, 2025, 7:35 PM

#

can you tell by the timestamp of when you restarted if that is from the most recent restart or the one before you fixed custom.yaml?

spiral hedge Mar 27, 2025, 7:37 PM

#

I believe after. You asked me to restart at 19:22 and I responded done at 19:32

elfin condor Mar 27, 2025, 7:38 PM

#

can you copy paste into the chatcat etc/nabox/harvest/user/rest/custom.yaml?

spiral hedge Mar 27, 2025, 7:39 PM

#

objects:
NFSClients: nfs_clients.yaml
Volume: custom_volume_flexgroup.yaml

elfin condor Mar 27, 2025, 7:42 PM

#

thanks. I think i see the (a) problem. We fixed rest/custom.yaml but not restperf/custom.yaml that is causing the merge problem which unfortunately is breaking rest when nabox does its merge. For restperf/custom.yaml, can you comment out all the lines, move the file somewhere else, etc. so we can focus on the NFSClients issue?

spiral hedge Getting this...

You need to put password again for modifications.

elfin condor Mar 27, 2025, 7:43 PM

#

@edgy harbor when logging this, it would be nice to also log the file that has the syntax error {"log":"time=2025-03-27T14:51:59.014Z level=ERROR source=havrest.go:49 msg=\"unable to merge config\" error=\"yaml: unmarshal errors:\\n line 4: cannot unmarshal !!seq into string\"\n","stream":"stdout","time":"2025-03-27T14:51:59.014711405Z"}

edgy harbor Mar 27, 2025, 7:43 PM

#

Good point !

elfin condor Mar 27, 2025, 7:45 PM

#

@edgy harbor also not sure if you expected it or not but a syntax error in restperf custom.yaml seems to cause rest custom.yaml merging to fail too. I assume an error bails? But might be worth trying to improve

spiral hedge Mar 27, 2025, 7:48 PM

#

After commenting out the restperf/custom.yaml and restarting, I'm not getting output from the docker logs command and also see data in NFS clients dashboard.

#

Sorry!!! 'now' not 'not' 😀

elfin condor Mar 27, 2025, 7:49 PM

#

🙂 I was confused

spiral hedge Mar 27, 2025, 7:49 PM

#

Meaning, it's working now

elfin condor Mar 27, 2025, 7:51 PM

#

Great! So three issues: 1) REST was not in your harvest.yml 2) rest/custom.yaml had a syntax error that prevented the NFSClients template from loading. 3) restperf/custom.yaml also had a syntax error that prevented the REST NFSClients template from loading

Thanks for all the help 🏆
