Question

server keeps crashing using mongodb

I use this command to hang up a mongodb in background and set dbpath to mount:

sudo mongod --dbpath /mnt/volume-nyc1-04/mongodata2 --fork --logpath /var/log/mongod.log --bind_ip 127.0.0.1

this works well for mongodata, but for mongodata2 whenever i type into command line the whole server just keep crashing and i have to log into console and power on.

This mongodata2 is a large db (300GB) with large collection (3billion rows). I am wondering what could cause the server crashing?

Hi @adrian3118b6a2c

If the server reboots, meaning kernel crash, then you should find some information in /var/log/kern.log https://help.ubuntu.com/community/DebuggingSystemCrash#log_files

But you’re using MongoDB incorrect. You shouldn’t run it as root - never. And if you run multiple MongoDBs at the same time, you need to set different PID, dataPath, listen address, etc.

Why are you running mongodb as root? What do you mean by “crashing”? Did you check the logs?
