Unable to restore QOS' Preempt value to default

[Trey Dockendorf]

Using version 14.03.4-2 I'm unable to reset a QOS' default Preempt value using sacctmgr. The documentation mentions "Setting a Preempt to '' (two single quotes with nothing between them) restores its default setting." but that is not working.

$ sacctmgr show qos normal format=name,preempt,preemptmode
Name Preempt PreemptMode
---------- ---------- -----------
normal cluster

$ sacctmgr -i modify qos normal set preempt=background
Modified qos...
normal

$ sacctmgr show qos normal format=name,preempt,preemptmode
Name Preempt PreemptMode
---------- ---------- -----------
normal background cluster

$ sacctmgr -i modify qos normal set preempt=''
sacctmgr: No error
Nothing modified

I'm able to fix the column in the database:

MariaDB [slurmdbd]> update qos_table set preempt='' where name='normal';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

Unfortunately I don't know C well enough to offer a patch. If I knew where to look in the source I might be able to fix it out :).
