Usage​

This release brings a container image equivalent to the upstream Ceph's image. At Clyso, we value your right to be free from vendor lock-in, and thus we make sure the our images are compatible with the upstream's Ceph releases. This means you will be able to upgrade to our image from an upstream release, and downgrade it back should you want to.

Container image​

The container image for CES version 25.03.2 can be found in our container registry at harbor.clyso.com/ces/ceph/ceph:ces-v25.03.2

CES 25.03.1​

Compatibility Note​

warning

When migrating from CES 25.03.1 back to upstream Ceph, avoid downgrading to Ceph 18.2.4 due to known upgrade issues. Instead, migrate to Ceph 18.2.7 or later for optimal compatibility.

CES 25.03.1 (Original)​

CES 25.03.1 is based on Reef 18.2.4.

These release notes are divided into two sections, upstream backports and downstream only patches. Upstream backports are a set of patches that didn't make it to Reef 18.2.4 but feel are vital to operating Ceph. Downstream only patches on the other hand are configuration changes we highly recommend to operators or changes we have yet to submit to the upstream Ceph community.

This release includes the following patches below plus the ceph-copilot module. This release does not include any of the clyso monitoring module and clyso dashboard.

Downstream Patches​

osd: default osd_op_type wpq​

  • mclock still unstable in corner cases in reef. Setting to wpq fixes some issues for now.

Upstream Backports​

cephadm: fix upgrade to reef​

orchestrator: public and cluster networks, comma separated not supported​

osd: Report health error if OSD public address is not within subnet​

common/pick_address: Add IPv6 support to is_addr_in_subnet​

rgw: fix checksum mismatch​

rgw/swift: tempurl fixes​

rgw/auth/s3: validate x-amz-content-sha256 for empty payloads​
