dmesg tells us why: [75960.625411] libceph: mon0 10.8.128.33:6789 feature set mismatch, my 4a042a42 < server's 104a042a42, missing 1000000000 http://cephnotes.ksperis.com/blog/2014/01/21/feature-set-mismatch-error-on-ceph-kernel-client 1000000000 is the feature bit for CRUSH_V2, i.e. newer indep or SET steps in your crushmap. You can either upgrade the kernel to 3.14 or later, which support these, or change your crush map to not use these features. I would suggest upgrading the kernel since newer ones have more bug fixes for rbd as well. Interesting. Indeed, the 3.14 kernel supports more support, but for the purpose of this test, the question is: how did this test run on RHEL7 that has a 3.10 kernel? Josh: Perhaps the RHEL 7.1 kernel ships with a newer kRBD? Harish: we should not be testing kRBD on Ubuntu anyway: we cannot fix those Ubuntu kernels, even if we find an issue, so kRBD support is only on RHEL. Looks like we forgot to drop that item when we made the test plan. Let's replace kRBD tests with some of your lower priority tests already in your lists. |
