Class Method Details

.parse(key, columns, data) ⇒ Object

Parses the results of LVMs commands. This does not handle when columns have no data and therefore these columns should be avoided. It returns the data with the prefix removed i.e. “lv_free” would be come “free” this however doesn’t descriminate and will turn something like “foo_bar” into “bar”
