Hi again,
I think I managed to make it working with:
$ slurmrestd -f /etc/slurm/slurmrestd.conf -a rest_auth/jwt -s
openapi/v0.0.36 -vvv 0.0.0.0:6820
Sample request:
$ curl -H "X-SLURM-USER-NAME:riggi" -H "X-SLURM-USER-TOKEN:${SLURM_JWT}"
http://localhost:6820/slurm/v0.0.36/ping
{
"meta": {
Ok,
I think I have found the plugins in:
/root/rpmbuild/BUILD/slurm-20.11.5/src/slurmrestd/plugins/openapi/
I did:
make
make install
and now I have:
$ slurmrestd -s list
slurmrestd: Possible OpenAPI plugins:
slurmrestd: openapi/v0.0.35
slurmrestd: openapi/v0.0.36
slurmrestd: openapi/dbv0.0.36
Thanks very much.
I found both files under:
/root/rpmbuild/BUILD/slurm-20.11.5/src/slurmrestd/plugins/auth/jwt/.libs/rest_auth_jwt.so
/root/rpmbuild/BUILD/slurm-20.11.5/src/slurmrestd/plugins/auth/local/.libs/rest_auth_local.so
It seems they weren't installed (any hints why?). By the way I tried

Thanks very much for your reply.
- I added this line to the slurm.conf file:
AuthAltParameters=jwt_key=/var/spool/slurmctld/jwt_hs256.key
I restarted the daemons but this does not change slurmrestd error. I guess
this is needed anyway after plugins are found, so thanks for pointing that
out.

It's not yet there:
The memory you tell Slurm (using the RealMemory value) is the memory the
jobs can use. So if your nodes have a minimum free RAM of 3353, I think set
RealMemory for your nodes to 3300MB. You always have to leave some RAM for
OS/caching etc. The way we calculate Slurm RAM is (physical RAM - GPFS

2) Installed slurm with:
rpmbuild -ta slurm-20.11.5.tar.bz2 --with mysql --with slurmrestd --with jwt
I don't see this "--with jwt" in the slurm.spec file:
[slurm-20.11.5]# grep "# --with"

Did you add a key?
AuthAltParameters=jwt_key=/etc/slurm/jwt.key
It needs to be present on the slurmdbd and slurmctld nodes.

Dear all,
I write you about how to properly setup slurmrestd.
I followed a recent post (
https://groups.google.com/g/slurm-users/c/VDeFmSDao1U/m/Yu0j-VNcBgAJ) but
slurmrestd fails with:
*slurmrestd: fatal: No authentication plugins to load*
Indeed when I run slurmrestd -a list, no plugin is
The reason why your nodes are drained is "Low RealMemory"
This reason is because you have told Slurm about the RAM on the node, but
it is less than the RAM on the node.
You have told Slurm that the amount of RAM on wn001 is 3934MB
What does
free -m
show on wn001?
The DBD looks good now!

Hi Sean
I made all the changes you recommended but the problem remains.
Attached you will find dbd & ctld log files an slurmd log file from one node
wn001. Also slum configuration.
scontrol show node wn001
NodeName=wn001 Arch=x86_64 CoresPerSocket=2
CPUAlloc=0 CPUTot=2
