Hi!
Is there a way to get the list of dynamic nodes that have been created but that are pending to get slurmd to run on them? I fail to see them with with either scontrol or sinfo:
root@ea-u24-dynamic-2511:~# scontrol show nodes | grep NodeName
NodeName=node001 Arch=x86_64 CoresPerSocket=1 NodeName=node002 Arch=x86_64 CoresPerSocket=1 NodeName=node003 Arch=x86_64 CoresPerSocket=1 root@ea-u24-dynamic-2511:~# sinfo -N -a
NODELIST NODES PARTITION STATE node001 1 defq* idle node002 1 defq* idle node003 1 defq* idle root@ea-u24-dynamic-2511:~# scontrol create NodeName=node004 .... state=FUTURE feature=dyn1
root@ea-u24-dynamic-2511:~# scontrol show nodes | grep NodeName
NodeName=node001 Arch=x86_64 CoresPerSocket=1 NodeName=node002 Arch=x86_64 CoresPerSocket=1 NodeName=node003 Arch=x86_64 CoresPerSocket=1 root@ea-u24-dynamic-2511:~# sinfo -N -a
NODELIST NODES PARTITION STATE node001 1 defq* idle node002 1 defq* idle node003 1 defq* idle root@ea-u24-dynamic-2511:~# scontrol version
slurm 25.11.2
Only when I start slurmd from node004 does it become visible (through scontrol only):
root@ea-u24-dynamic-2511:~# ssh node004 /cm/local/apps/slurm/current/sbin/slurmd -Z -f /cm/shared/apps/slurm/etc/slurm/slurm.conf
root@ea-u24-dynamic-2511:~# sinfo -N -a
NODELIST NODES PARTITION STATE node001 1 defq* idle node002 1 defq* idle node003 1 defq* idle root@ea-u24-dynamic-2511:~# scontrol show nodes | grep NodeName
NodeName=node001 Arch=x86_64 CoresPerSocket=1 NodeName=node002 Arch=x86_64 CoresPerSocket=1 NodeName=node003 Arch=x86_64 CoresPerSocket=1 NodeName=node004 Arch=x86_64 CoresPerSocket=1
Thanks in advance.

IIRC, they don't truly exist in slurm until slurmd starts and they register with slurmctld.
Until then there is just a number placeholder saying there can be up to X nodes in the cluster.
So your quest would be like wondering the name of the person in seat 5A before anyone has purchased it.

I believe you need the --future flag for scontrol and sinfo to see nodes in the "FUTURE" state.
That pulled it off, thanks!
$ scontrol show nodes node004 Node node004 not found $ scontrol show nodes --future node004 | grep NodeName NodeName=node004 CoresPerSocket=1

Hooray! Glad it worked for you.
