Optimizing Objectstore Storage
In versions prior to 2022.4, Ceph was using the replicated type of data pool, which takes 900 GiB of space across the cluster to store 50 GiB of objects. Opting for the erasure-coded pool instead of the replicated type reduces the storage space required to store the same 50 GiB of objects from 900 GiB to 450 GiB.
You can optimize Objectstore storage only if the Ceph version running within your Automation Suite cluster is 15.x.
The scenarios where your Automation Suite cluster hosts Ceph 15.x are the following:
- Fresh installation of Automation Suite 2022.4.0;
- Existing installations of Automation Suite 2021.10.0, 2021.10.1, 2021.10.2;
- Upgrade from Automation Suite 2021.10.0, 2021.10.1, 2021.10.2 to 2022.4.0.
Automation Suite 2021.10.3 and 2021.10.4 hosts Ceph 16.x, where you cannot take advantages of an optimized Objectstore storage. We are working on providing a solution for this.
To check the installed Ceph version, run the following command on any server node:
kubectl -n rook-ceph get deployment -l rook_cluster=rook-ceph -o jsonpath='{range .items[*]}{"ceph-version="}{.metadata.labels.ceph-version}{"\n"}{end}' | sort | uniq
kubectl -n rook-ceph get deployment -l rook_cluster=rook-ceph -o jsonpath='{range .items[*]}{"ceph-version="}{.metadata.labels.ceph-version}{"\n"}{end}' | sort | uniq
The following sample output shows a Ceph version that is not supported for storage optimization:
ceph-version=16.2.7-0
ceph-version=16.2.7-0
To optimize the Objectstore storage, you need to migrate the replicated Ceph algorithm to the erasure encoding algorithm. The following table shows the ways you can migrate the data.
