Question

I am trying to create collection in mongo, on the server running ubuntu

creating collection from the shell

db.createCollection('collName')

{
   "errmsg" : "exception: assertion util/mmap.cpp:169",
   "code" : 0,
   "ok" : 0
}

I tried to google about it but with no success.
Any ideas how to handle this?

PS. I am not out of space and I volume is writeable

Ok, I found the problem
When mongo was just installed, one should have to create directories for its data

$ sudo mkdir -p /data/db/
$ sudo chown `id -u` /data/db

after this restart mongo
