=head2 get_status
This parses the DRBD status on the local or remote system. It returns a JSON -> decoded reference.
This parses the DRBD status on the local or remote system. The data collected is stored in the following hashes;
- drbd::status::<hostname>::resource::<resource_name>::{ap-in-flight,congested,connection-state,peer-node-id,rs-in-flight}
- drbd::status::<hostname>::resource::<resource_name>::connection::<peer_hostname>::volume::<volume>::{has-online-verify-details,has-sync-details,out-of-sync,peer-client,peer-disk-state,pending,percent-in-sync,received,replication-state,resync-suspended,sent,unacked}
- # If the volume is resyncing, these additional values will be set:
- drbd::status::<hostname>::resource::<resource_name>::connection::<peer_hostname>::volume::<volume>::{db-dt MiB-s,db0-dt0 MiB-s,db1-dt1 MiB-s,estimated-seconds-to-finish,percent-resync-done,rs-db0-sectors,rs-db1-sectors,rs-dt-start-ms,rs-dt0-ms,rs-dt1-ms,rs-failed,rs-paused-ms,rs-same-csum,rs-total,want}
- drbd::status::<hostname>::resource::<resource>::devices::volume::<volume>::{al-writes,bm-writes,client,disk-state,lower-pending,minor,quorum,read,size,upper-pending,written}
If any data was stored in a previous call, it will be deleted before the new data is collected and stored.
