Hi Peter Sabaini, Filip Palmberg, Thanks for test verification. As your testing confirms, the capacity was doubled.
If this is still not enough, would you please specify the number that would work for you? It seems this was not clarified during the previous iteration. My suggestion we log another LP bug with a requirement for a limit that would works and solve that as a new activity. This fix is already release, and arguable works as intended. ** Description changed: [SRU] 2.74.1: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2138629 [ Impact ] This issue was only on a MicroCeph deployment, it is not expected to happen on desktop setups. The symptoms are snap.microceph.osd and snap.microceph.daemon exit immediately with status 1. All OSDs on the affected host go down, cluster remains up. Repeated restarts show the same error. See: https://github.com/canonical/microceph/issues/669 [ Test Plan ] 1. Reproduce with snapd deb < 2.74.1 No need to reproduce, just point to evidence showing previous failures. 2. Prove fixed with snapd deb 2.74.1 + https://github.com/canonical/snapd/pull/16505 doubled the limit. + Request testing a similar deployment with the modified version of snapd - and confirm the issues does not happen anymore. + and confirm that the capacity was doubled. ---original--- snapd seems to set up a max of 500 devices in the bpf map for purposes of filtering: https://github.com/canonical/snapd/blob/dcaf86ce5c0e66efe384bd4418cdaadb10b2d205/cmd/libsnap-confine-private/device-cgroup-support.c#L393 Proxying a user report where a system carries >80 VMs and seems to run the map out of entries: https://github.com/canonical/microceph/issues/669 VMs there are configured with MicroCeph, setting up close to 500 rbd devices. We may need to make the max_entries configurable to accomodate setups such as this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2139099 Title: Hardcoded max of 500 entries in bpf map To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/2139099/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
