MongoDB mongorestore failure: locale::facet::_S_create_c_locale name not valid
MongodbLocaleUbuntu 12.04MongodumpMongorestoreMongodb Problem Overview
I created a dump with mongodump on computer A (ubuntu 12.04 server). I moved it to computer B (ubuntu 12.04 server) and typed:
> mongorestore -db db_name --drop db_dump_path
It failed and it reported:
> connected to: 127.0.0.1
> terminate called after throwing an instance of 'std::runtime_error'
> what(): locale::facet::_S_create_c_locale name not valid
> Aborted
I've successfully accomplished this operation before and this strange behavior has never occurred. What do I need to do to fix this?
Mongodb Solutions
Solution 1 - Mongodb
On my distro "locale-gen" was not installed and it turned out all I had to do is set the LC_ALL environment variable. so the following command fixed it:
export LC_ALL="en_US.UTF-8"
hopefully it will help someone else...
Solution 2 - Mongodb
Actually it isn't strictly related to MongoDB. Somehow the language on computer B was not defined correctly. I managed to fix it by typing:
> sudo locale-gen en_US en_US.UTF-8
> sudo locale-gen it_IT it_IT.UTF-8
> sudo locale-gen xx_xx xx_XX.UTF-8 ...
> sudo dpkg-reconfigure locales
These commands will generate and configure the needed locales. After those steps mongorestore got back working as usual.
Solution 3 - Mongodb
Exporting LC_ALL="en_US.UTF-8" only works if you have the en_US locale installed. If you want to avoid installing the locales package (or its equivalent on distributions other than Debian derivatives), then you can instead use:
export LC_ALL=C.UTF-8
which will not require any extra locale data.
Solution 4 - Mongodb
If you are using a Mac OSX and SSH this might be issued by wrong LC_CTYPE.
$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE=UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
Unset the wrong var.
$ unset LC_CTYPE
Check whether locale is working fine.
$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
Now mongo also should do fine.
Solution 5 - Mongodb
To make the fix permanent you can edit one of those files:
- sudo vim /etc/default/locale
- sudo vim /etc/environment
And add the line LC_ALL="en_US.UTF-8"
Solution 6 - Mongodb
Got same problem on debian 7 without locale-gen (command not found) installed.
I solved this way:
su
apt-get install locales
dpkg-reconfigure locales # select locales you want!
Now mongodb should start.
