Ceph Squid (v19)

This document lists known critical bugs affecting Ceph Squid (v19) releases.

Squid Deployed OSDs Are Crashing​

Severity: Critical
Affected Versions: 19.2.*
Bug Report: https://tracker.ceph.com/issues/70390

Description​

OSDs created in v19 may crash. The issue affects only newly deployed OSDs using Squid, while previously deployed OSDs run fine. It is likely caused by the Elastic Shared Blob implementation introduced in this PR https://github.com/ceph/ceph/pull/53178, and ceph-bluestore-tool repair cannot fix it.

Recommendation​

  • For now, run ceph config set osd bluestore_elastic_shared_blobs 0 on any Squid cluster before adding new OSDs
  • Unfortunately, this will not help OSDs already deployed in Squid—the only known fix for them is redeployment

S3 DeleteBucketLifecycle Does Not Delete Config​

Severity: Medium
Affected Versions: 19.2.3
Bug Report: https://tracker.ceph.com/issues/71083

Description​

The S3 DeleteBucketLifecycle API call fails to actually delete the lifecycle configuration from the bucket, causing S3 compatibility issues. This is a regression introduced in squid 19.2.3.

Recommendation​

  • Upgrade to a fixed version when available
  • Avoid using DeleteBucketLifecycle API in affected versions
