Hi
When making “cinder backup-create”
We found the process “cinder-backup” use 100% util of 1 CPU
core on an OpenStack Controller node.
It not just causes a bad backup performance, also make the
openstack-cinder-backup unstable.
Especially when we make several backup at the same time.
The Controller Node has 40 CPU cores.
Can we assign more CPU resources to cinder-backup ?
This has been addressed in [1], but it may not be in the release
you're using.
[1]
https://github.com/openstack/cinder/commit/373b52404151d80e83004a37d543f825846edea1
In addition to the change above we also have
https://review.openstack.org/#/c/537003/ which should also help with the
stability issues. That has been backported as far as Pike.
The change for multiple processes is only in master for the Rocky
release right now.
