- list of node names with bad data returned (unreachable, etc.)
- list of instances with degraded disks (that should be activated)
In normal operation, both lists should be empty. A non-empty
instance list 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.
