Copy file from archer2 to puma2

General

Hi CMS team,

I would like to copy some input files for a run from archer 2 to puma 2. To test the syntax I am moving a very small file. When I am logged into puma2 and try the following command the terminal hangs:

rsync -av penmaher@login.archer2.ac.uk:/home/n02/n02/penmaher/dev_r5518_GO6_package_penmaher/info.txt ./

When I try to ssh into archer2 from puma2 I the terminal also hangs. Have I failed to set up a ssh-key or is this by design not possible (i.e. the ssh path would be archer2login>puma2>archer2login which seems a bit odd) and I should copy files another way?

Thanks in advance!

Penny

Hi Penny,

What input files are you wanting to copy over? All model input files need to be on ARCHER2 not PUMA2. Please don’t put large files on PUMA2 as it has a very limited disk.

You can access the PUMA2 home disk from ARCHER2 at: /home/n02/n02-puma/penmaher and use normal cp.

You can also use rsync but it would be rsync -av <login-node>:/home/n02/n02/....... where <login-node> is one of ln0[1-4]
Cheers,
Ros

Excellent! Thanks for the info. I am realising now I should put the files in /work/n02/n02/ and I think that should sort it! Appreciate you getting back to me to quickly.
