On Tuesday, November 10th from 10:00am to 12:00pm the Nebula web interface and API interfaces will be unavailable for maintenance.
We will work on:
- Testing the addition of new storage servers, but restricting cinder access to specific projects (like the way Nova handles availability zones)
- Security hardening
- Possibly uninstalling the aging and possibly deprecated Amazon EC2 API that comes with OpenStack and replacing it with a third-party plugin
- Possibly installing Ceilometer
Instances and networking to those instances will continue to work as expected during the maintenance time. Functions that try to provision new instances or volumes will not work, however.
Maintenance was completed at 12:00pm CST.
- Another storage node was added to the storage pool
- Security updates were installed
- Discovered that volume deletion zeroes out the file, so 10TB test volume requires 10,000,000 writes to delete; changed this going forward to only zero out the first 50MB
