Initializes this class.
|
Checks if the instance disks are activated.
|
Check prerequisites. This checks that the instance is in the cluster.
|

|
Create new storage on the primary or secondary node. This is only used for same-node replaces, not for changing the secondary node, hence we don't want to modify the existing disk. |
Replace a disk on the primary or secondary for DRBD 8. The algorithm for replace is quite complicated:
Failures are not very well handled. |
Update the configuration of disks to have a new secondary.
