Cryosparcm restart stalls at command_core: started after change in IP address

Install, Configure and Update
1

Hi
We have cryosparc installed in our standalone workstation (Centos7) with the latest version and patch. All the programs were running without issues until yesterday when our Computer Center assigned a new IP address to our workstation (The “hostname” is same). Now when I restarted cryosparc with “cryosparcm restart”, it stalls at command_core: started.

cryosparcm-restart

When I run “cryosparcm status”, it shows:

cryosparcm-status
cryosparcm-status730×371 99.5 KB

I checked the ports 39000-39010 and they are open. Can you please help me solve the issue?

Are there any error messages at or near the end of output from
cryosparcm log command_core?

Has the workstation been rebooted since the address reassignment? If not, I suggest

  • determining the process id of the supervisord mongod process
    ps xu | grep cryosparc | grep supervisor
    and killing that process
  • confirming that the CryoSPARC database is no longer running
    ps xu | grep cryosparc | grep mongo
    and killing (but not kill -9, details) the mongod process if necessary.
  • rebooting the computer
  • then trying cryosparcm start

Does cryosparcm start work after reboot? If not, what are

  • error messages in shell
  • the output of hostname -f
  • the output of cryosparcm log command_core

Hi @cryo-fan , you can be sure CS sees your host by adding

export CRYOSPARC_MASTER_HOSTNAME="mycomputer"
export CRYOSPARC_FORCE_HOSTNAME=true

on your config.sh. Maybe it will work. Of course backup and stop cryosparc before the modification… :upside_down_face:

Hello @wtempel and @jucastil,
Thanks so much for the helpful suggestions. Cryosparc is now running smoothly in our workstation.
