@ahkumar
@AlexTalker thank you, will just stick to stopping iml-storage-server.target & chroma-agent.service and removing python2-iml-agent-4.1.4-1.el7.noarch. & clean up /var/lib/chroma
@AlexTalker Hope this works ..
Alex Talker
@AlexTalker
@ahkumar Yeah, good luck
Amit Kumar
@ahkumar
@AlexTalker thank you!!
Amit Kumar
@ahkumar
@AlexTalker @jgrund removing agent and reinstalling went smooth. thank you for your input and help!
Joe Grund
@jgrund
@ahkumar Thanks to @AlexTalker glad it worked for you
Amit Kumar
@ahkumar
@jgrund yes thank you @AlexTalker as well. One of these warnings have been repeating itself. Can this be made not to complain: (/usr/lib/python2.7/site-packages/requests/packages/urllib3/connectionpool.py:821: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html) ??
@jgrund another question: can I dump the metrics(jobstats) to elasticsearch ? so I can have some historical info?
Joe Grund
@jgrund
@ahkumar, you should be able to script some ingest against the IML REST API
Amit Kumar
@ahkumar
@jgrund Great. I will use the API and script it found an example in the docs. Also wondering if you have an answer for the InsecureRequestWarning above?
Joe Grund
@jgrund
WIll need to take a look futher. Can you open an issue at https://github.com/whamcloud/integrated-manager-for-lustre/issues/new/choose with more detail?
Amit Kumar
@ahkumar
@jgrund sounds good will do!
Amit Kumar
@ahkumar
@jgrund Wondering how frequently is "jobstats" collected? and is it stored in the database that I can retrieve for historical data on jobs IOPS etc? if yes is there an API i can use to get that infromation?
Alex Talker
@AlexTalker
@ahkumar Yes, if you grant access to postgres manually, you can find jobstat info, look for tables with numbers in their names. As for API, AFAIK, the current one just streams information from database by websocket and you can inspect it on jobstat web ui page. Jobstats collected each 10 seconds I think.
Alex Talker
@AlexTalker
@ahkumar Here's my approach to request statistics from PostgreSQL: select s.dt, s."sum", e.name, e.id, t.name from chroma_core_sample_10 s, chroma_core_series e, chroma_core_managedtarget t where s.id = e.id and e.object_id = t.id and t.state = 'mounted' --and t.name = 'lustre1-OST0001' and s.dt >= '2019-06-28 12:30:40.000Z' and s.dt <= '2019-06-28 12:33:10.000Z' and e.name like '%_write_bytes%';
Change parameters to fit your needs, you may remove some conditions to check if data is present
Joe Grund
@jgrund
@ahkumar @AlexTalker There is also Rest JSON API access if you don’t want to hit the db directly

Is it possible to create a non-HA server with IML? We have a customer with a single MDS/MGS node and the filesystem format fails at configuring corosync and doesn't even attempt to format or start targets
Joe Grund
@jgrund
Deploy Lustre from IML, but no HA?
Not at the moment. IML can monitor existing filesystems without needing HA
bmerchant
@bmerchant
That's what I figured, thanks for confirming. We went manual install + monitor mode route

@bmerchant
Is it possible to recover/reset the superuser password for IML? This is IML 3.0.0.0 and no other users exist besides what was created during initial chroma-config install
Joe Grund
@jgrund
@bmerchant yes
on the manager node:
cd /usr/share/chroma-manager
python ./manage.py changepassword <username>
bmerchant
@bmerchant
Perfect, thanks!

when I reposync -n --repoid=managerforlustre-manager-for-lustre, a warning : cannot find repository managerforlustre-manager-for-lustre. no repositories found

I am having the same issue when attempting to create an offline repo "cannot find repository managerforlustre-manager-for-lustre. no repositories found"
zmahiri47
@zmahiri47
Update - I was able to successfully perform reposync via dnf by including the complete repoid name. For me the complete command as " dnf reposync -n repoid=copr:copr.fedorainfracloud.org:managerforlustre:manager-for-lustre "

Hello, I can't seem to add any servers to IML (6.0). When I add a server, packages install, but when I add a server the chroma-agent.log give the "daemon WARNING get_nids: failed to open" . Also, when I try to import any of the chroma modules in python I get errors like "ImportError: No module named chroma_core.lib.storage_plugin.base_plugin". How can install the chroma_core modules?
