I've created a san using Logical Volumes as backing-store iSCSI LUNs (tgt)
the target iqn.2011-09.com.pany.san:target1 using the LV /dev/vg0/t1l1 as backing-store
the initiator sees the device as /dev/sda
 on the initiator i've created 2 partition /dev/sda1 (swap) and /dev/sda2 (ext4)

I want to be able to create backup on of the ext4 fs, without stopping the initiator!

The solution i came up with involves the snapshot feature of LVM, kpartx from multipath-tools and some backup method (i prefer rdiff-backup or safekeep).

steps:

CouchDB and multiple tags

The problem

Given a set of documents, each associated with multiple tags, how can I retrieve the documents tagged with an arbitrary set of tags?

My solution

qw3r

#!/usr/bin/env ruby

#
# A quick script to dump an overview of all the open issues in all my github projects
#

require 'octokit'
require 'awesome_print'
require 'rainbow'

qw3r

module CouchDBAttachments
  def attachment(*args)
    lambda do |env|
      request = ActionDispatch::Request.new(env)
      doc = DocWithAttachments.get(request.params[:doc])
      serve_attachment(doc, request.params[:path])
    end
  end
