Adding Ubuntu Ceph packaging task here. 30-ceph-osd.conf file is owned by ceph-osd package as follows.
$ dpkg -S /etc/sysctl.d/30-ceph-osd.conf ceph-osd: /etc/sysctl.d/30-ceph-osd.conf However, as far as I see in 15.2.8-0ubuntu0.20.04.1/focal there is no place in /var/lib/dpkg/info/ceph-osd.postinst activating the sysctl file so it requires a reboot basically or manual intervention is required to apply the value in the package. I think that's why fs.aio-max-nr wasn't applied in the first place. ** Also affects: ceph (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903221 Title: ERROR: error creating empty object store in /var/lib/ceph/osd/ceph- NN/: (11) Resource temporarily unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/charm-ceph-osd/+bug/1903221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
