[slurm-users] [EXT] Re: Missing data in sreport for a time period in slurm

That's good to hear. I had the same issue a few years ago, also with Slurm 19, and that was the advice the Slurm support staff gave me.

I do recommend upgrading your Slurm though. sreport is muuuuuch faster in later Slurm versions.

Thank you all so much for your help in solving this issue.

Hi Sean,
Yes, i have changed those values to that time. After restarting slurmdbd, timestamp changed again to today's date but sreport still not showing data for a year.

Did you change those values to a timestamp before May 2020 like I suggested? If you do that, then Slurm will regenerate the data needed for sreport to work properly.

Dear All,
By checking the value of last ran table, hourly rollup shows today's date.
+---------------+--------------+----------------+-------------
| hourly_rollup | daily_rollup | monthly_rollup        |
+---------------+--------------+----------------+-------------
|    1634617800 |   1634581800 |     1634581785 |
+---------------+--------------+----------------+-------------
As we can see the data from last 1 month in sreport but not the data from may 2020 to sept 21, but the same can be visible through sacct.

sreport keeps a track of when it has done the last rollup calculations in the database.

Open MySQL for your Slurm accounting database, do

select * from slurm_acct_db.clustername_last_ran_table;

where slurm_acct_db is your accounting database name (slurm_acct_db is default), and clustername is the name of your cluster in Slurm.

The numbers are UNIX timestamps. e.g for mine

select * from thespian_slurm_acct_db.thespian_last_ran_table;
+---------------+--------------+----------------+
| hourly_rollup | daily_rollup | monthly_rollup |
+---------------+--------------+----------------+
|    1634580000 |   1634562000 |     1633420706 |
+---------------+--------------+----------------+
1 row in set (0.00 sec)

1634580000 is Mon Oct 18 2021 18:00:00 GMT+0000

If you set those values to something before 26 May 2020, you can then either wait for the rollups to happen again, or you can trigger them to start by restarting slurmdbd. Once they start, you can monitor their progress by running that SQL query again. Once they have caught up again, sreport should be back to normal.

Dear all,
As i recall, there were some runaway jobs one month ago, and i used this command to fix it, and from that date only(from 15 Sept) , previous data from 26 May 2020 to Sept 14 2021
has been gone in sreport.
I hope there is no co-relation between using this command and data missing in sreport.

I have backup from that day of mysql, if you can suggest some way to integrate that data into slurm table in mysql.
Or is there any other way so that i can reinitialize the slurm utillization tables from initial.

Does "sacctmgr show runawayjobs" reveal any problematic jobs?
