Locating the SLURM Image on the EMS

1. The image.json file from the previous step needs to exist on the EMS in /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>/image.json with permissions:

   CODE

   -rw-r--r-- 1 slurm slurm 568 May  9 01:26 /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>/image.json

2. The initramfs image or the initrd file need to be located on the EMS in /xcompute/slurm/bin/vm-mode/<AMI_ID>/<INIT_FILE> with permissions:

   CODE

   -rw-r--r-- 1 slurm slurm 56202253 May  9 01:19 /xcompute/slurm/bin/vm-mode/ami-050bf59b877e9f593/initramfs-3.10.0-1160.105.1.el7.x86_64.img

This can be accomplished with scp -i <path-to-private-key> [ image.json | <INIT_FILE> ]${EMS_ADDRESS}:/tmp.

Once on the EMS, the root user can finalize placement and permissions

for image.json:

mkdir /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>
cp /tmp/image.json /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>/image.json
chown -R slurm:slurm /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>
chmod 755 /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>
chmod 644 /xcompute/slurm/bin/xcompute-daemon/data/images/<IMAGE_NAME>/image.json

and for the INIT assets:

mkdir /xcompute/slurm/bin/vm-mode/<AMI_ID>
cp /tmp/initramfs-3.10.0-1160.105.1.el7.x86_64.img /xcompute/slurm/bin/vm-mode/<AMI_ID>/
chown -R slurm:slurm /xcompute/slurm/bin/vm-mode/<AMI_ID>
chmod 755 /xcompute/slurm/bin/vm-mode/<AMI_ID>
chmod 644 /xcompute/slurm/bin/vm-mode/<AMI_ID>/initramfs-3.10.0-1160.105.1.el7.x86_64.img
