Repair Server (ioGuardian)#

A repair server provides a potential repair mechanism after a system experiences a problem that extends beyond its redundancy tolerance (e.g. simultaneous, multiple drive failures spanning multiple nodes). Typically, a repair server is a sync destination that contains a fairly recent replication of the given system. A repair server will automatically attempt to pull back any needed blocks from the remote system, potentially avoiding the need to roll back using a snapshot. It is generally recommended that you have a repair server in place whenever possible.

There is a higher chance of repair success when there is a good network connection, with relatively low latency, between the system and its repair server.

A repair server is created using the existing outgoing sync configuration: vSAN Host (address of the remote destination), vSAN Port, system-generated authorized username/password, and encryption setting enabled or disabled based on the associated sync configuration.

Create a Repair Server from an Outgoing Sync (common method)#

Repair servers may be auto-generated when Adding Sites to the Dashboard.

Typically, a repair server is created from an outgoing sync because the sync destination would contain a recent copy of the data. This is the recommended method in most cases.

  1. From the outgoing sync dashboard, click Create Repair Server on the left menu.
  2. Enter a Name for the repair server. Use a name that will be helpful for future administration, for example a name that includes that of the remote system.
  3. Optionally, a Description can be entered to store additional information.
  4. Click Submit to complete the creation. A repair server is created using the outgoing sync configuration details, including: vSAN Host (address of the remote destination), vSAN Port, system-generated authorized username/password, and encryption setting.

Create a Repair Server from the Repair Servers List Page#

In instances where there is no current outgoing sync from which to configure the repair server (e.g. a three-way sync configuration or a previous sync destination that is no longer in use), the following instructions can be used:

  1. From the Main Dashboard, select Backup/DR from the left menu.
  2. Click Repair Servers on the left menu.
  3. Click New on the left menu.
  4. Enter a Name for the repair server. Use a name that will be helpful for future administration, for example a name that includes that of the remote system.
  5. Optionally, a Description can be entered to store additional information.

Credentials can be copied from an existing outgoing sync:

  • Select Copy in the Credentialling dropdown list
  • Select desired sync in the Copy Credentials from dropdown list

Manual Credentialling#

To manually enter credential information: select Manual in the Credentialling dropdown list.

Credential Fields#

  • vSAN Host - url to the root level of the remote system
  • vSAN Port - default 14201, a different port can be used but must also be configured on the remote side with ports open on intermediate firewall(s)
  • User
  • Password and Confirm Password for the specified VergeOS user
  • Encryption
