1 DRBD is a software-based, shared-nothing, replicated storage solution
2 mirroring the content of block devices (hard disks, partitions, logical
3 volumes etc.) between hosts.
5 DRBD mirrors data
7 * in real time. Replication occurs continuously while applications
8 modify the data on the device.
9 * transparently. Applications need not be aware that the data is stored
10 on multiple hosts.
11 * synchronously or asynchronously. With synchronous mirroring,
12 applications are notified of write completions after the writes have
13 been carried out on all (connected) hosts. With asynchronous mirroring,
14 applications are notified of write completions when the writes have
15 completed locally, which usually is before they have propagated to the
16 other hosts.
