Database spawn error under other user accounts

closed

(YH) #1

I successfully installed cryosparc v2 with user for example user1. Everything is ok. When I log in with another user account and launch the cryosparcm, I got the error message:

$cryosparcm start
Starting cryoSPARC System master process..
CryoSPARC is not already running.

I checked the cryosparcm status:
$ cryosparcm status

I also found some text in database.log file
[initandlisten] WiredTiger error (1) [1535011333:146083][19076:0x7fcc1ad5fd40], file:WiredTiger.wt, connection: /opt/bioSoft/cryosparc-2.0/cryosparc2_database/WiredTiger.wt: handle-open: open: Operation not permitted

It seems that there is a permissions issue with the WiredTiger.wt file. But I have already set all of the subfolders and files in the cryosparc-2 folder owned/writable by everyone.

I cannot find any solution what is wrong with it.

Thanks a lot.

Dear Soyvia,

I have been having the same issue. Any luck in solving your problem? Thank you.

I’m having the same issue with my install. Has anyone been able to resolve this issue? Any help is greatly appreciated!

Hi @soyvia,

This seems like it’s happening because you installed cryosparc with one user, but turned it on with another. Make sure cryosparc is turned off on all accounts/machines, delete the lock file, and reinstall it with the user you want cryosparc to run on.

Hi,
Thanks so much for the reply. I will reinstall it following your suggestion, but how about more than one users use the same workstation and everyone must log on the workstation with his own account?
Thanks again.

Hi @soyvia,

If you take a look at the overall setup description here:

It mentions that only one UNIX user needs to run cryoSPARC. You can access cryoSPARC through the user interface (the address will be displayed to you upon first installation). If you keep following the installation instructions, it’ll explain how you can create multiple user accounts that can access the UI.

Hi sarulthasan,
you wrote:

How can I do this? I’m not sure to which lock file you are referring to.
Many thanks

Hi @maarten.tuijtel,

In this case of this issue, I instructed OP to delete the .lock file because a previous user maintained a lock on the database. This is not always the solution because deleting the lock file can corrupt the database. Is is possible if you can start a new post with your specific problem and I can help you there?
