Package ganeti :: Module opcodes :: Class OpGroupVerifyDisks

Class OpGroupVerifyDisks

Verifies the status of all disks in a node group.

Result: a tuple of three elements:

dict of node names with issues (values: error msg)
list of instances with degraded disks (that should be activated)
dict of instances with missing logical volumes (values: (node, vol) pairs with details about the missing volumes)

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.
