Description of problem: As documented in BZ# 1236473 [1] and KCS 2176931 [2], while using Ceph for ephemeral storage, openstack adds up the ceph storage seen in each storage node rather than just using the real amount of ceph storage. This results in incorrect storage utilization showing in openstack. Request a warning be added to openstack 6 documentation regarding this issue since it is not likely it will be fixed in Openstack 6. [1] https://bugzilla.redhat.com/1236473 [2] https://access.redhat.com/solutions/2176931
Assigning to Don for review. Don - this one will need to be targeted for the 6.0 documentation on the osp6-juno branch.
A warning describing the discrepancy between Ceph and Nova RE: available ephemeral storage is now available publicly on the following links: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/6/html-single/Release_Notes/index.html#idp5499120 https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/6/html-single/Configuration_Reference_Guide/index.html#ch_configuring-openstack-compute https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/6/html-single/Command-Line_Interface_Reference_Guide/index.html#novaclient_subcommand_hypervisor-stats Scott, please advise if there are any other docs we should add the warning, or if there's anything else? If not, please close the BZ. Thanks!
The warning looks good to me. Scott, do you have any feedback?
