mgr modules' subinterpreter use and their pyo3 incompatibility

by Matthew Vernon

Hi, I'm referring to https://tracker.ceph.com/issues/64213 and the older https://tracker.ceph.com/issues/63529 (which relates to the dashboard mgr module specifically). But basically, the use of pyo3 isn't safe in subinterpreters[0], and it introduced a check to error out on such use. This is already causing problems in Debian bookworm (I think my chance that a version of pyo3 with the check got released there first - it looks like both Ubuntu 23.04 and now centos9 are likely also affected?), although the MR that takes the problematic code out of the dashboard may help somewhat (and I've opened an MR to backport it to reef - https://github.com/ceph/ceph/pull/55689 ). I may have missed discussion on it, but is there a plan for addressing this set of issues, please? It doesn't look like multiple subinterpreter support in pyo3 is going to happen any time soon... Regards, Matthew [0] https://github.com/PyO3/pyo3/issues/576

In today's ever-evolving world of travel and exploration, there is a growing fascination with alternative forms of experiencing new places and cultures. One such trend that has gained significant traction is the use of psychedelics, ketamine, and cannabis to enhance the travel experience.

Tripsitter: A Psychedelics, Ketamine, & Cannabis Encyclopedia is here to guide curious travelers on this journey. Tripsitter is an all-encompassing resource that delves deep into the world of psychedelics, ketamine, and cannabis.

Re: Insane number of "osd_snap purged_snap" keys in monstore db due to rbd-mirror

by Eugen Block

Hi, this thread has been inactive for quite some time, I thought I'd try to revive it. Is there any chance for a better mon store trimming regarding purged_snap and purge_epoch keys? Thanks! Eugen

User + Dev Meetup February 22 - CephFS Snapshots story!

by Neha Ojha

Hi everyone, You are invited to join us at the User + Dev meeting this week Thursday, February 22 at 10:00 AM Eastern Time! Focus Topic: CephFS Snapshots Evaluation Presented by: Enrico Bocchi and Abhishek Lekshmanan, Ceph operators from CERN From the presenters: Ceph at CERN provides block, object, and file storage backing the IT infrastructure of the Organization. CephFS, in particular, is largely used through the integration with OpenStack Manila by container-based workloads (Kubernetes, OpenShift), HPC MPI clusters, and as a general-purpose networked file system for enterprise groupware and open infrastructure technologies (code/software repositories, monitoring, analytics, etc.). Our presentation focuses on CephFS snapshots and their implications on performance and stability. Snapshots would be a valuable addition to our existing CephFS service, as they allow for storage rollback and disaster recovery through mirroring. According to our observations, however, they introduce a non-negligible performance penalty and may jeopardize the stability of the file system. In particular, we would like to discuss: 1. Experiences with CephFS snapshots from other operators in the Ceph community. 2. Tools and strategies one can deploy to pre-empty or mitigate issues. 3. How to effectively contribute with upstream developers and interested community users to address the identified limitations. Feel free to add questions or additional topics under the "Open Discussion" section on the agenda: https://pad.ceph.com/p/ceph-user-dev-monthly-minutes If you have an idea for a focus topic you'd like to present at a future meeting, you are welcome to submit it to this Google Form: https://docs.google.com/forms/d/e/1FAIpQLSdboBhxVoBZoaHm8xSmeBoemuXoV_rmh4v… Any Ceph user or developer is eligible to submit! Thanks, Neha
