Sysfs parser library to get blockdevice topology

Device Topology

A simple package that parses the sysfs directory to obtain the blockdevice topology.

The project is still in Alpha stage.

Usage:

• To use as a binary, build the code

go build -o topo main.go
./topo /dev/sdb

• To use as a package. Import the topology package and create a Device object using the device path. This will be used to get the dependent devices.

Terms used:

1. Holders : Holders are the list of blockdevices that are held by the given blockdevice. eg: /dev/sda1 is held by /dev/sda since it is a partition. Therefore the holder list of /dev/sda will have /dev/sda1
2. Slaves : Slaves are the list of blockdevices to which the given device acts as a slave. eg: /dev/sda1 is a slave for /dev/sda. Therefore slave list of /dev/sda1 will contain /dev/sda
