Public bug reported: nbd does not handle a disk resize correctly. This has been fixed upstream: https://github.com/torvalds/linux/commit/639812a1ed9bf49ae2c026086fbf975339cd1eef
On Ubuntu Bionic with a "4.15.0-34-generic #37-Ubuntu" kernel a resize of a (Ceph) rbd image does not propagate to a "rbd-nbd" mapped disk, until it's unmapped / remapped. See https://tracker.ceph.com/issues/23137. Other "nbd" mapped disks might suffer from the same behaviour (not tested). Ubuntu mainline kernel (4.19-rc5) works correct with regards to this rbd resize rbd-nbd mapped image. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: nbd rbd-nbd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1794766 Title: Apply upstream kernel fix to relevant Ubuntu kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794766/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
