Database failure

Hi - our cryoSPARC database suddenly died on us earlier this week. Everything seemed to be running fine then the web UI stopped populating items and when I refreshed the page it crashed. When I try to restart cryoSPARC I get a database spawn error:

[hansenbry@D01985551 ~]$ cryosparcm restart
CryoSPARC is not already running.
If you would like to restart, use cryosparcm restart
Starting cryoSPARC System master process..
CryoSPARC is not already running.
database: ERROR (spawn error)

When I checked the status it listed a database failure:

The log I’m not sure how to interpret and was hoping someone here could help me figure out how to recover from the crash or if I just need to reinstall:

-----  END BACKTRACE  -----

I did crop the log to just the first round of the backtrace error. If more of the log is needed I can add it. I just ran out of characters if the whole log was posted

Thanks for any help!

Hi @hansenbry,

Unfortunately we haven’t come across an error like this before. Do you know if there were any changes to your filesystem configuration around the time you received this error?

It seems like the main error within the backtrace is Fatal Assertion 28558 at src/mongo/db/storage/wiredtiger/wiredtiger_util.cpp 361. Our best guess is to try searching for this assertion error in the context of MongoDB. WiredTiger is MongoDB’s default storage engine, so all problems seem to point to some sort of storage or filesystem malfunction.

Please let us know if you have any additional questions, we’ll try our best to help resolve the issue.

Regards,
Suhail

Thanks for the suggestiong @sdawood! I’ll pass this along to our IT group here. This was my feeling too, but wanted to confirm.

Hi @hansenbry, please let us know if there has been any progress on this. The logs also mention that the file

/net/ai-rmlhpc/gs1/RTS/EM/Software/Proc1-cryosparc/cryosparc2_database/mongod.lock

exists, which indicates an unclean shutdown. You can stop cryosparc, remove the .lock file and try to start cryosparc again, which often fixes unclean shutdown issues.

hi @apunjani - We’re working to restore the cryosparc2_database folder from a daily backup that we have before the initial issue started. I did however try to do a cryosparm stop then remove the mongod.lock file and restart, but I still get the database spawn error and the mongod.lock file get recreated.

Hi @hansenbry,

This might be caused by the following series of events:

  1. The initial sock file goes missing (this can happen if the /tmp directory is cleared
  2. The original mongo process is still running, but supervisor doesn’t know that its running because there is no sock file
  3. The backup/restore commands use supervisor to start the database if its not already running
  4. Supervisor reports to the backup/restore commands that the mongo process is not running
  5. The backup/restore commands turn on the database using supervisor, creating a new sock file
  6. The mongo database throws exceptions because it has two processes trying to acquire a lock on the db

Please kill the mongo processes, delete the lock files, and restart cryoSPARC.

ps -ax | grep “mongod”
kill <process_pid>
//delete the .lock file
cryosparcm start

Hi @stephan I got the database spawn error to clear up. However, now when I try and login to the UI it says ‘User not found’. Did something get majorly mucked up to where I would be better re-installing?
