Description Steve Ford 2019-01-18 07:40:07 MST

Hello SchedMD,

We updated SLURM to 18.08.4 to fix an issue we encountered using seff (https://bugs.schedmd.com/show_bug.cgi?id=5882)

Now that we're updated, we are experiencing a different issue. Seff has errors and reports incorrect usage:

17.11.8 seff:

This looks like the same issue described in https://bugs.schedmd.com/show_bug.cgi?id=6004 and https://bugs.schedmd.com/show_bug.cgi?id=6315. There are patches suggested in https://bugs.schedmd.com/show_bug.cgi?id=6004, can your developers take a look at these before I apply them?

Thank you,
Steve

Hi Steve,

I'm debating with dev. team about this issue.

Will keep you posted.

Comment 3 Jurij Pečar 2019-01-21 09:20:26 MST

We have the same problem and I just tried out that patch, which solved it for us.

Comment 4 Felip Moll 2019-01-23 03:11:28 MST

Hi, this particular issue has already been fixed in bug 6004 for
18.08.5 and 19.05.0pre2. I am marking this bug as a duplicate.

In bug 6004 comment 6 you will find also a note about the limitations of seff.

We have another internal bug for addressing these limitations.
