Protocol A is suitable for DR hosts with higher latency connections, but the DR host will be allowed to fall slightly behind the nodes. Protocol C ensures that the DR host is never behind, but could hurt storage performance.

Note: Protocol A is OK when replicating to a DR host. When used, it allows the DR host to fall behind the nodes, which helps avoids a performance hit when the network latency / speed to the DR host is higher than tolerable. Between nodes, protocol C must always be used, which ensures synchronous replication.

[#!variable!resource_state!#] Enabled Disabled s Up Down Down The resource is stopped. StandAlone No network configuration available. The resource has not yet been connected, or has been administratively disconnected (using drbdadm disconnect), or has dropped its connection due to failed authentication or split brain. Connecting This node is waiting until the peer node becomes visible on the network. Connected A DRBD connection has been established, data mirroring is now active. This is the normal state. Disconnected This indicates that the connection is down. Disconnecting Temporary state during disconnection. The next state is StandAlone. Unconnected Temporary state, prior to a connection attempt. Possible next states: Connecting. Timeout Temporary state following a timeout in the communication with the peer. Next state: Unconnected. BrokenPipe Temporary state after the connection to the peer was lost. Next state: Unconnected. NetworkFailure Temporary state after the connection to the partner was lost. Next state: Unconnected. ProtocolError Temporary state after the connection to the partner was lost. Next state: Unconnected. TearDown Temporary state. The peer is closing the connection. Next state: Unconnected. Off The volume is not replicated over this connection, since the connection is not Connected. Established All writes to that volume are replicated online. This is the normal state. StartingSyncS Full synchronization, initiated by the administrator, is just starting. The next possible states are: SyncSource or PausedSyncS. StartingSyncT Full synchronization, initiated by the administrator, is just starting. Next state: WFSyncUUID. WFBitMapS Partial synchronization is just starting. Next possible states: SyncSource or PausedSyncS. WFBitMapT Partial synchronization is just starting. Next possible state: WFSyncUUID. WFSyncUUID Synchronization is about to begin. Next possible states: SyncTarget or PausedSyncT. SyncSource Synchronization is currently running, with the local node being the source of synchronization. SyncTarget Synchronization is currently running, with the local node being the target of synchronization. PausedSyncS The local node is the source of an ongoing synchronization, but synchronization is currently paused. This may be due to a dependency on the completion of another synchronization process, or due to synchronization having been manually interrupted by drbdadm pause-sync. PausedSyncT The local node is the target of an ongoing synchronization, but synchronization is currently paused. This may be due to a dependency on the completion of another synchronization process, or due to synchronization having been manually interrupted by drbdadm pause-sync. VerifyS On-line device verification is currently running, with the local node being the source of verification. VerifyT On-line device verification is currently running, with the local node being the target of verification. Ahead Data replication was suspended, since the link can not cope with the load. This state is enabled by the configuration on-congestion option (see Configuring congestion policies and suspended replication). Behind Data replication was suspended by the peer, since the link can not cope with the load. This state is enabled by the configuration on-congestion option on the peer node (see Configuring congestion policies and suspended replication). Diskless No local block device has been assigned to the DRBD driver. This may mean that the resource has never attached to its backing device, that it has been manually detached using drbdadm detach, or that it automatically detached after a lower-level I/O error. Inconsistent The data is inconsistent. This status occurs immediately upon creation of a new resource, on both nodes (before the initial full sync). Also, this status is found in one node (the synchronization target) during synchronization. Outdated Resource data is consistent, but outdated. DUnknown This state is used for the peer disk if no network connection is available. Consistent Consistent data of a node without connection. When the connection is established, it is decided whether the data is UpToDate or Outdated. UpToDate Consistent, up-to-date state of the data. This is the normal state Attaching Transient state while reading meta data. Detaching Transient state while detaching and waiting for ongoing IOs to complete. Failed Transient state following an I/O failure report by the local block device. Next state: Diskless. Note: Despite the name, this is rarely an actual issue. Negotiating Transient state when an Attach is carried out on an already-Connected DRBD device. Primary The resource is currently in the primary role, and may be read from and written to. This role only occurs on one of the two nodes, unless dual-primary mode is enabled. Secondary The resource is currently in the secondary role. It normally receives updates from its peer (unless running in disconnected mode), but may neither be read from nor written to. This role may occur on one or both nodes. Unknown The resource’s role is currently unknown. The local resource role never has this status. It is only displayed for the peer’s resource role, and only in disconnected mode.
