Clients and Servers with b_ieel3_0 build 222. Created Lustre file system.<br/> 2. Unmounted and upgraded all clients and Servers to 2.10.1. Mounted lustre again.<br/> 3. Unmounted Clients and Downgraded them to b_ieel3_0 build 222. Mounted Lustre again when nodes were up.<br/> 4. Unmounted MDS and downgraded it to b_ieel3_0 build 222. Mounted lustre and it worked this time.<br/> 5. Ran sanity now and the test ended abruptly after the completion of test_117 for both zfs and ldiskfs.</p> <p>When I checked the states of nodes, MDT and one client were unmounted, OSTs and 2nd client were mounted.</p> <p>Results:<br/> ldiskfs - <a href="https://testing.hpdd.intel.com/test_sessions/df43fbf4-a2fb-11e7-b786-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/df43fbf4-a2fb-11e7-b786-5254006e85c2</a><br/> zfs - <a href="https://testing.hpdd.intel.com/test_sessions/335a5516-a2fd-11e7-bb19-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/335a5516-a2fd-11e7-bb19-5254006e85c2</a></p> LU-10039

ioctl error after downgrade

Bug Minor Open Unresolved Zhenyu Xu Andreas Dilger Wed, 27 Sep 2017 19:02:12 +0000 Thu, 28 Sep 2017 05:13:26 +0000 Lustre 2.10.0 Lustre 2.10.1 0 3 <p>After discussion with Saurabh, it seems that the user tools (in particular <tt>lfs</tt>) were not downgraded with the kernel modules. This is generating errors when using <tt>lfs setstripe</tt> in sanity test_27A, which is setting the default layout on the root directory:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>error on ioctl 0x4008669a for '/mnt/lustre' (3): Invalid argument error: setstripe: create stripe file '/mnt/lustre' failed error on ioctl 0x4008669a for '/mnt/lustre' (3): Invalid argument error: setstripe: create stripe file '/mnt/lustre' failed </pre> </div></div> <p>The ioctl is <tt>LL_IOC_LOV_SETSTRIPE</tt> (0x4000 &gt;&gt; (<tt>_IOC_DIRSHIFT</tt> = 14) = <tt>_IOC_WRITE</tt>, 0x08 = sizeof(long), 0x66 = 'f', 0x9a = 154). However, it isn't clear why the kernel is complaining about the <tt>struct lov_mds_md</tt> that is being sent. Is this a bad magic, or something else? Since we aren't using composite layouts for these files, it should be compatible with existing tools.</p> <p>Re-ran the sanity using exact same steps as above and sanity run did not ended abruptly this time. Before running sanity I ran individual tests i.e. test_27A and test_65i which failed in previous run, but they passed when ran alone in second run. Results for second run are as follows:<br/> ldiskfs- <a href="https://testing.hpdd.intel.com/test_sessions/d735f45c-a40a-11e7-b786-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/d735f45c-a40a-11e7-b786-5254006e85c2</a><br/> zfs- <a href="https://testing.hpdd.intel.com/test_sessions/0a221f12-a40b-11e7-b786-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/0a221f12-a40b-11e7-b786-5254006e85c2</a></p> Related LU-10027 Development Rank 1|hzzkxb: Rank (Obsolete) 9223372036854775807 Severity
