Description:
RAID 1 over TCP/IP for Linux (user utilities)
Drbd is a block device which is designed to build high availability clusters by providing a virtual shared device which keeps disks in nodes synchronised using TCP/IP. This simulates RAID 1 but avoiding the use of uncommon hardware (shared SCSI buses or Fibre Channel). It is currently limited to fail-over HA clusters. . This package contains the programs that will control the drbd kernel module provided in the Linux kernel.
