Remove a cluster

Install, Configure and Update
1

Hi,
On my clustered cryosparc system, I added a cluster, in the name of the cluster I had added spaces in the name that it looks like “HI gpu cluster”. I realized that I can’t easily access it via the api because the spaces break the python api calls. I added two more ‘clusters’ with the properly formatted name (no spaces) and that is working fine. I can’t remove the “HI gpu cluster” now because of the spaces, is there another way to remove this cluster from the cryosparc database?
Thanks,
Jeff

Hi @jmcdonal,

cryosparcm cluster remove <name>

# removes a cluster configuration from the scheduler

Thanks Stephan, I did try that as well as a number of variations (single quotes, single+double, etc) of trying to pass the string:

% cryosparcm cluster remove "HI gpu cluster"
HI gpu cluster
Removing cluster HI gpu cluster

Hello all,

I have the same issue. Unfortunately I gave quite information on the lane name without spaces…
grep 'name' cluster_info.json: "name" : "nodes with slurm pinning and SSD",
My bad, but … did you find out how to run cryosparcm cluster remove, or how to remove it?

Thanks…

Hi @jmcdonal, @jucastil,

Is it possible if you can try deleting the lane from your instance via the CLI?

cryosparcm cli "remove_scheduler_lane('HI gpu cluster')"

if that doesn’t work, try this command:

cryosparcm cli "remove_scheduler_target_cluster('HI gpu cluster')"

Hello @stephan @jmcdonal,

Sorry for the delay but the lane was in use :wink:
I can confirm that in our case
cryosparcm cli "remove_scheduler_lane('nodes with slurm pinning and SSD')"
worked ( version: v2.16.1-live_deeppick_privatebeta, slurm 20.02.4).
After deletion I’ve added the line again with the new name (and a new cache size :smiley:).
Thanks Stephan for the info!
