What's New in Ceph Octopus
- All Ceph daemons are now running as containers.
- New Ceph dashboard
- PG autoscaling: You can allow the cluster to either make recommendations or automatically tune PGs based on how you will use your ceph cluster by enabling pg-autoscaling.
- Partial object recovery replaces log-based recovery to improve the speed of recovery.
- Snapshot trimming improvement eliminates metadata in the OSD map that (previously) would grow with cluster age.
- Bluestore performance improvement
- Support new RBD client cache policy write-around as the default setting. The write-around policy differs from the write-back policy in that it does not attempt to service read requests from the cache, unlike the write-back policy, and is, therefore, faster for high-performance write workloads.
- Snapshot-based RBD mirroring reduces the I/O overhead of journal-based snapshots. Snapshot-based mirroring supports kernel RBD that journal-based mirroring doesn't.
- RGW supports object lock for Write-Once-Read-Many (WORM) data protection.
What's new in UVS Manager v2.15.18
- Ceph Version: 15.2.x (Octopus)
- Operating System
○ Upgrade Linux to CentOS 8
○ Kernel upgrade to 5.4.100
- Deployment & Management:
○ Use cephadm and ceph orchestrator as the deployment and management tools
○ Modify the UVS manager to meet the requirement of deploying ceph on containers
○ Modify the UVS manager to adopt the change of Ceph Octopus.
○ Modify the console RESTORE function to accelerate the container deployment.
- Automatically deploy NTP Server:When deploying the new cluster, the UVS manager will automatically use the node as the default NTP server when deploying a new cluster. This new feature avoids users forgetting to configure the NTP server. Users can change the NTP server after cluster deployment.
- Network Configuration:
○ Add configuration option for separating the Ceph public and in-cluster network.
○ Replace the Linux bonding module with Open vSwitch SLB bonding to provide a better stable network.
- OSD:Add an option for deploy OSD to use the SATA HDD/SSD as the bluestore storage.
- MON:Users can deploy multiple Ceph monitors in parallel to shorten the deployment time.
- RADOS Gateway
○ Simplify the deployment of new RGW
○ Unify the stand-alone and multisite RGW. All new deployed RGW will be multi-site ready.
- Ceph File System:Simplify the deployment of the Ceph file system. Now users can create the CephFS, pools, and metadata server (MDS) on one user interface.
- Demo license:A demo license is embedded in the new Mars 400 shipments. This simplifies the deployment of a new cluster.
- Bug Fixed:
○ Fix bug of unable to control the disk LEDs. (Backport to v2.14.17-3)
○ Fix bug of binding /var/tmp & /tmp all to M.2 SSD /tmp (Backport to v2.14.17-3)
○ Fix wrong setting of CephFS max_mds after the UVS manager upgrade (Backport to v2.14.17-3)
○ Use log rotation to prevent the logs from over consume the storage.
