Safe portable wrapper for block device opperations

A highly parallel Perl 5 interpreter written in Rust

Executes given block in new forked process. After timeout process is killed. Return value of forked prcess is given through tmpfs in /dev/shm as serialized YAML object.

= ebs_conductor The EBS Conductor is a library for managing Amazon Elastic Block Storage volumes and snapshots. It is designed to persist a specific set of data (a "lineage") between different compute instances. EBS Conductor can be used on it's own, but it's most powerful when executed on an EC2 instance using Chef, and the ebs_conductor cookbook[https://github.com/rgeyer/cookbooks/tree/master/cookbooks/ebs_conductor] == Examples === Attach a new 1GB blan volume in the lineage "foobar" to a linux box at /dev/sdb1 ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.attach_from_lineage('i-abcd1234', 'foobar', 1, '/dev/sdb1') === Attach a specific snapshot to a 1GB volume in the lineage "foobar" to a linux box at /devb/sdb1 ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.attach_from_lineage('i-abcd1234', 'foobar', 1, '/dev/sdb1' {:snapshot_id => 'snap-abcd1234'}) === Snapshot the lineage "foobar", do not purge any old snapshots in the lineage ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar') === Snapshot the lineage "foobar", and purge old snapshots so that only 7 remain ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar', {:history_to_keep => 7}) === Snapshot the lineage "foobar" from the specified volume_id This is useful if you're trying to start a lineage from a "naked" instance, or if you are trying to create a new lineage from an existing one ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar', {:history_to_keep => 7, :volume_id => 'vol-abcd1234'}) == List of To Do Items * Support for stripes in a lineage == Copyright Copyright (c) 2011 Ryan Geyer.

This is Daemons 1.0.10 with the addition of Chris Kline's fix from http://blog.rapleaf.com/dev/?p=19 Daemons provides an easy way to wrap existing ruby scripts (for example a self-written server) to be run as a daemon and to be controlled by simple start/stop/restart commands. If you want, you can also use daemons to run blocks of ruby code in a daemon process and to control these processes from the main application. Besides this basic functionality, daemons offers many advanced features like exception backtracing and logging (in case your ruby script crashes) and monitoring and automatic restarting of your processes if they crash. Daemons includes the daemonize.rb script written by Travis Whitton to do the daemonization process.
