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.

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.
