Doc Text: |
Cause: race condition when updating a batch of nodes (we verified the issue on 8+ nodes) to (un)schedulable with "oadm manage-node --schedulable=<true|false>".
Consequence: several nodes couldn't be updated with the "object has been modified" error.
Fix: use a patch on the "unschedulable" field of the node object instead of a full update.
Result: all nodes could be properly updated schedulable and/or unschedulable (tested on a 60 nodes cluster).
