Updating a worker node?

Install, Configure and Update
1

Hello,

I recently tried to update cryosparc with the command: cryosparcm update

This is what the output was:

 Now updating worker nodes.
 
All workers: 
XXXXXXX cryosparc_user@XXXXXXX
 -------------------------------------------------
Updating worker XXXXXXX
Remote update
scp ./cryosparc2_worker.tar.gz cryosparc_user@XXXXXXX:/home/cryosparc_user/software/cryosparc/cryosparc2_worker
cryosparc_user@XXXXXXX's password: 
Authentication failed.
lost connection
Failed to update XXXXXXX! Skipping...
 -------------------------------------------------
 ---------------------------------------------------
 Done updating all worker nodes.
 If any nodes failed to update, you can manually update them.
 Cluster worker installations must be manually updated.
 
 To update manually, simply copy the cryosparc2_worker.tar.gz
 file into the cryosparc worker installation directory, and then run 
    $ bin/cryosparcw update 
 from inside the worker installation directory.

I tried searching around but didn’t really see any instruction for how to update the worker node. I already tried the manual update that was suggested in this output, and it said that the cryosparc2_worker was already updated.

TIA!

Hi @merandamasse, it looks like you don’t have passwordless SSH access between the master and worker nodes. See instructions on how to set this up here: 3. Password-less SSH Access

Be sure to replace remote_username and remote_hostname with your worker config (the outputs of the whoami and hostname commands on the worker machine).

Hope that helps,

Nick
