Getting the facter value of $mount from $partitions.

[Hiu]

hi all,

I am wondering if I would like to retrieve the mount points values from the facter. From the facter -p, I can see that I do have the information. e.g.

partitions => {

"sda1"=>{

"mount"=>"/boot", 

"uuid"=>"4e5014d1-080a-4182-aa89-bc83159b85fb", 

"filesystem"=>"ext4", 

"size"=>"614400"}, 

"sda2"=>{

"mount"=>"/", 

"uuid"=>"edbab169-7983-4e38-9c71-24f0f88cccaa", 

"filesystem"=>"ext4", 

"size"=>"18257920"}, 

"sda3"=>{

"uuid"=>"b9674244-6686-49b0-b778-91052d78767f", 

"filesystem"=>"swap", 

"size"=>"2097152"}

}

And $mount is the one that I am looking for. Question: how can i loop through the $partitions data structure and harvest $mount and detect if there is a mount point call "/data". thanks!

It can be done.  Your best bet is probably a custom function or an inline template, either one of which can be used to process your data with arbitrary Ruby code.  Exactly how that would look depends a lot on what you want to do with the data, and in what form you want to receive the result.  If all you want to know is whether there is any x for which $::partitions[x]['mount'] == '/data', then it might look like this:

$has_data_partition = inline_template("<%= (! @partitions.select { | fs, opts | '/data' == opts['mount'] }.empty? ).to_s %>")
if $has_data_partition == 'true' {
  # ...
} else {
  # ...
}
