pblock-bd

Utility to attach pblock connection as a block device.

Under the hood it uses nbd kernel interface and BUSE to communicate with it.

`nbd` and `pblock` differences

Device size

pblock doesn't have notion of file size and nbd requires it to create block device. As a result you have to pass device size in pblock-bd command args.

Transactional access

I didn't found any information about nbd being transactional, so currently every read or write on nbd is wrapped in separate pblock transaction.

Install

make install PREFIX=~/.local

Tests

Dependencies:

pgspawn
pblock utilities

Currently tests require root previlages. Test runner uses sudo to provide them.
