Remote bridge
The remoteBridge submenu is used to register or deregister a remote bridge
for a configured location.
Registering and de-registering
To register a remote bridge use storpool remoteBridge register <location-name>
<IP address> <public-key> as shown in the example below:
# storpool remoteBridge register StorPool-Rome 10.1.100.10 ju9jtefeb8idz.ngmrsntnzhsei.grefq7kzmj7zo.nno515u6ftna6
OK
This will register the StorPool-Rome location with an IP address of
10.1.100.10 and the above public key.
In case of a change in the IP address or the public key of a remote location, the remote bridge could be de-registered and then registered again with the required parameters; here is an example:
# storpool remoteBridge deregister 10.1.100.10
OK
# storpool remoteBridge register StorPool-Rome 78.90.13.150 8nbr9q162tjh.ahb6ueg16kk2.mb7y2zj2hn1ru.5km8qut54x7z
OK
A remote bridge might be registered with noCrypto in case of a secure
interconnect between the clusters; typical use-case is a Multi-cluster
setup, with other sub-clusters in the same datacenter.
Minimum deletion delay
To enable deferred deletion on unexport from the remote site the
minimumDeleteDelay flag should also be set, the format of the command is
storpool remoteBridge register <location-name> <IP address> <public-key>
minimumDeleteDelay <minimumDeleteDelay>, where the last parameter is a time
period provided as X[smhd] - X is an integer and s, m, h, and
d are seconds, minutes, hours and days accordingly.
For example, if you want to register the remote bridge for the StorPool-Rome
location with a minimumDeleteDelay of one day you can do it like this:
# storpool remoteBridge register StorPool-Rome 78.90.13.150 8nbr9q162tjh.ahb6ueg16kk2.mb7y2zj2hn1ru.5km8qut54x7z minimumDeleteDelay 1d
OK
After this operation all snapshots sent from the remote cluster could be
unexported later with the deleteAfter parameter set (check the
Remote snapshots section). Any deleteAfter parameters lower than
the minimumDeleteDelay will be overridden by the bridge in the remote
cluster. All such events will be logged on the node with the active bridge
in the remote cluster.
For more information about deferred deletion, see Multi site.
Listing registered remote bridges
To list all registered remote bridges use:
# storpool remoteBridge list
StorPool> remoteBridge list
------------------------------------------------------------------------------------------------------------------------------
| ip | remote | minimumDeleteDelay | publicKey | noCrypto |

Status of remote bridges
You can see the state of all registered bridges to clusters in other locations or sub-clusters in the same location:
# storpool remoteBridge status
