Class OpGroupVerifyDisks

source code


Verifies the status of all disks in a node group.

Result: a tuple of three elements:

In normal operation, all lists should be empty. A non-empty instance list (3rd element of the result) is still ok (errors were fixed) but non-empty node list means some node is down, and probably there are unfixable drbd errors.

Note that only instances that are drbd-based are taken into consideration. This might need to be revisited in the future.
