This is a fork of the original ec2-consistent-snapshot written by Eric Hammond.
The difference is that this version has support for MongoDB.
On Ubuntu Lucid EC2 instance: sudo apt-get -y install build-essential libio-socket-ssl-perl libdatetime-perl sudo PERL_MM_USE_DEFAULT=1 cpan -fi MongoDB MongoDB::Admin Copy this ec2-consistent-snapshot to /usr/bin/ replacing old file.
Below is an example command for snapshotting Mongo. It will lock and fsync the DB, take the snapshot, and then unlock it. You can add a --stop to have Mongo restart afterwards.
ec2-consistent-snapshot \ --mongo \ --xfs-filesystem /data \ --region us-east-1 \ --description "RAID snapshot $(date +'%Y-%m-%d %H:%M:%S')" \ vol-VOL1 vol-VOL2 vol-VOL3 vol-VOL4 vol-VOL5 vol-VOL6 vol-VOL7 vol-VOL8
