Thanks Wannes. Those are the caveats around EC optimisation that I alluded to below. Since we don't have any EC on this cluster that should not be relevant... Regards, Chris On 02/02/2026 09:30, Wannes Smet via ceph-users wrote:

I'd like to know whether anyone has any good or bad experiences with Tentacle 20. 2. 0 in a production environment. I have the opportunity to upgrade a small production cluster from 19. 2. 3 to 20. 2. 0. It uses Cephadm/RBD/CephFS/RGW with R3 only ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization.

I'd like to know whether anyone has any good or bad experiences with Tentacle 20.2.0 in a production environment.

I have the opportunity to upgrade a small production cluster from 19.2.3 to 20.2.0. It uses Cephadm/RBD/CephFS/RGW with R3 only (no EC, so the known caveats around EC optimisations won't be relevant).

My experiences trying it in a lab test environment have been positive. But it would be good to know if anyone is encountering any problems with it in real life.
