Cryosparc V2 hangs during startup

rdrighetto · August 21, 2018, 10:16am

I am trying to install cryosparc v2 as a single workstation following the instructions provided. After installing the master without issues, when I first try to start it it hangs as follows:

cryosparc_user@bs-zorro01:~/cryosparc2_master$ cryosparcm start
Starting cryoSPARC System master process..
CryoSPARC is not already running.
database: started
command_core: started

And nothing happens after that for… ever. if I hit Ctrl+C and try to proceed with the installation instructions (create user), I get this error:

The OS is Ubuntu 16.04.2 LTS. How can I get cryosparc V2 to start?

Thank you!

I encountered similar problem as rdrighetto. After installing the master program, when I first start it it hangs after it started command_core. Then I hit Ctrl+C and proceed with the next step and got the error message:

If this is incorrect, you should re-run this command with the flag --sshstr <ssh string>

I also checked the cryosparm status:
$ cryosparcm status
----------------------------------------------------------------------------

The OS is Centos 7.3. What is wrong with the installation? Thanks a lot.

I got now the same problem. My computer died while cryosparc was running. However after restart I get almost exactly the same problem.

cryosparcm start
Starting cryoSPARC System master process…
CryoSPARC is not already running.
database: started
command_core: started

and there it hangs. However if I Ctrl+C I get no more output.

cryosparcm process status:

command_core RUNNING pid 4587, uptime 0:02:07
command_proxy STOPPED Not started
command_vis STOPPED Not started
database RUNNING pid 4510, uptime 0:02:09
watchdog_dev STOPPED Not started
webapp STOPPED Not started
webapp_dev STOPPED Not started

Any idea what could be the problem?

Best,

David

I found the solution for me. The master node did not reach itself. due to network issues. Now it works again.

RD_Cryo · October 7, 2018, 11:13am

It looks like I am having a very similar problem.
Could you please elaborate further about they way you solved it?
Thanks,
Ron

david.haselbach · October 10, 2018, 6:06am

I tried to reach all the nodes including the master node via the ssh string that I had given in the installation. and noticed that the masternode itself was not reachable anymore due to renaming of hostnames by our IT department. So I suggest to check whether you could ssh everywhere you specified.

Hey,

I get the same error as rdrighetto. I try to set-up cryosparc 2.5 on a workstation, following the ’ Quick Install: Single workstation’ . How this error can be solved? Has anyone found a solution? I think the answer from david.haselbach does not apply for a single workstation, am I right?

Thanks for all hints,

Andrzej

Hi @andrzej,

Can you paste the contents of the file cryosparc2_master/config.sh (please ensure to censor your license ID).

andrzej · March 4, 2019, 5:28pm

Here is my config file

export CRYOSPARC_LICENSE_ID="XX"
export CRYOSPARC_MASTER_HOSTNAME="XX"
export CRYOSPARC_DB_PATH="/usr/local/cryosparc/cryosparc2_database"
export CRYOSPARC_BASE_PORT=39000
export CRYOSPARC_DEVELOP=false
export CRYOSPARC_INSECURE=false

Hi @andrzej,

Are you running cryoSPARC on CentOS? Can you post the output of cryosparcm log command_core?

andrzej · March 6, 2019, 9:06am

Hi,

Here the command output:

$ cryosparcm log command_core
COMMAND CORE STARTED ===  2019-03-04 07:01:34.472665  ==========================
