https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-620 Lustre <p>I have a reproducable test case of a page bug, which is clearly reported on a kernel with additional debugging enabled.</p> <p> $ dd if=/dev/zero of=/net/lustre/file bs=4096 count=1<br/> $ rm /net/lustre/file<br/> BUG: Bad page state in process rm pfn:21fe6a<br/> page:ffffea00076fa730 flags:800000000000000c count:0 mapcount:0 mapping:(null) index:1</p> <p>The bug occurs on unlink() of a file shortly after it was written to.</p> <p>If there is a delay of a few seconds before the rm, all is okay. Truncate works, but a subsequent unlink rm can fail if it is quick enough.</p> <p>It appears that this bug could be the cause of some kind of mis accounting of the kernel's page cache, which causes lockups when the task is running in a cgroup. Originally I brought this up in a mailing list thread: </p> <p><a href="http://lists.lustre.org/pipermail/lustre-devel/2011-July/003865.html" class="external-link" target="_blank" rel="nofollow noopener">http://lists.lustre.org/pipermail/lustre-devel/2011-July/003865.html</a><br/> <a href="http://lists.lustre.org/pipermail/lustre-devel/2011-August/003876.html" class="external-link" target="_blank" rel="nofollow noopener">http://lists.lustre.org/pipermail/lustre-devel/2011-August/003876.html</a></p> <p>Here's a full example, taken today on the attached kernel config. The process is <em>not</em> running in cgroup, although the kernel is built with cgroup.</p> <p>BUG: Bad page state in process rm pfn:77813<br/> page:ffffea0002914688 flags:400000000000000c count:0 mapcount:0 mapping:(null) index:0<br/> Pid: 1173, comm: rm Not tainted 2.6.32.28-ml #8<br/> Call Trace:<br/> <span class="error">&#91;&lt;ffffffff81094ab2&gt;&#93;</span> bad_page+0xd2/0x130<br/> <span class="error">&#91;&lt;ffffffff810c4c39&gt;&#93;</span> ? lookup_page_cgroup_used+0x9/0x20<br/> <span class="error">&#91;&lt;ffffffff810978ea&gt;&#93;</span> free_hot_cold_page+0x6a/0x2d0<br/> <span class="error">&#91;&lt;ffffffff81097bab&gt;&#93;</span> free_hot_page+0xb/0x10<br/> <span class="error">&#91;&lt;ffffffff8109a65a&gt;&#93;</span> put_page+0xea/0x140<br/> <span class="error">&#91;&lt;ffffffffa04fc5c7&gt;&#93;</span> ll_page_removal_cb+0x207/0x510 <span class="error">&#91;lustre&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa041207b&gt;&#93;</span> cache_remove_lock+0x1ab/0x29c <span class="error">&#91;osc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa03fafad&gt;&#93;</span> osc_extent_blocking_cb+0x25d/0x2e0 <span class="error">&#91;osc&#93;</span><br/> <span class="error">&#91;&lt;ffffffff8137bcf6&gt;&#93;</span> ? _spin_unlock+0x26/0x30<br/> <span class="error">&#91;&lt;ffffffffa02db058&gt;&#93;</span> ? unlock_res_and_lock+0x58/0x100 <span class="error">&#91;ptlrpc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa02df630&gt;&#93;</span> ldlm_cancel_callback+0x60/0xf0 <span class="error">&#91;ptlrpc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa02f877c&gt;&#93;</span> ldlm_cli_cancel_local+0x6c/0x350 <span class="error">&#91;ptlrpc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa02fa960&gt;&#93;</span> ldlm_cancel_list+0xf0/0x240 <span class="error">&#91;ptlrpc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa02fac67&gt;&#93;</span> ldlm_cancel_resource_local+0x1b7/0x2d0 <span class="error">&#91;ptlrpc&#93;</span><br/> <span class="error">&#91;&lt;ffffffff81070f99&gt;&#93;</span> ? is_module_address+0x9/0x20<br/> <span class="error">&#91;&lt;ffffffffa03fcb57&gt;&#93;</span> osc_destroy+0x107/0x730 <span class="error">&#91;osc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa04b6a65&gt;&#93;</span> ? lov_prep_destroy_set+0x285/0x970 <span class="error">&#91;lov&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa04a07c8&gt;&#93;</span> lov_destroy+0x568/0xf20 <span class="error">&#91;lov&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa05355e3&gt;&#93;</span> ll_objects_destroy+0x4e3/0x18c0 <span class="error">&#91;lustre&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa046d099&gt;&#93;</span> ? mdc_reint+0xd9/0x270 <span class="error">&#91;mdc&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa0537098&gt;&#93;</span> ll_unlink_generic+0x298/0x360 <span class="error">&#91;lustre&#93;</span><br/> <span class="error">&#91;&lt;ffffffff8137a65f&gt;&#93;</span> ? __mutex_lock_common+0x27f/0x3b0<br/> <span class="error">&#91;&lt;ffffffff810d3c7e&gt;&#93;</span> ? vfs_unlink+0x5e/0xd0<br/> <span class="error">&#91;&lt;ffffffffa01a65c9&gt;&#93;</span> ? cfs_free+0x9/0x10 <span class="error">&#91;libcfs&#93;</span><br/> <span class="error">&#91;&lt;ffffffffa053716d&gt;&#93;</span> ll_unlink+0xd/0x10 <span class="error">&#91;lustre&#93;</span><br/> <span class="error">&#91;&lt;ffffffff810d3cad&gt;&#93;</span> vfs_unlink+0x8d/0xd0<br/> <span class="error">&#91;&lt;ffffffff810d6245&gt;&#93;</span> ? lookup_hash+0x35/0x50<br/> <span class="error">&#91;&lt;ffffffff810d7613&gt;&#93;</span> do_unlinkat+0x183/0x1c0<br/> <span class="error">&#91;&lt;ffffffff8137b828&gt;&#93;</span> ? lockdep_sys_exit_thunk+0x35/0x67<br/> <span class="error">&#91;&lt;ffffffff8137b7b2&gt;&#93;</span> ? trace_hardirqs_on_thunk+0x3a/0x3f<br/> <span class="error">&#91;&lt;ffffffff810d77ad&gt;&#93;</span> sys_unlinkat+0x1d/0x40<br/> <span class="error">&#91;&lt;ffffffff8100b3c2&gt;&#93;</span> system_call_fastpath+0x16/0x1b</p> Client: Lustre b1_8 Git 999530e, Linux 2.6.32.8 LU-620

"Bad page state" reported after unlink

Bug Blocker Resolved Fixed Zhenyu Xu Mark Hills Tue, 23 Aug 2011 07:57:37 +0000 Wed, 9 May 2012 12:21:50 +0000 Fri, 16 Mar 2012 08:42:55 +0000 Lustre 2.1.0 Lustre 2.1.2 Lustre 1.8.6 Lustre 2.2.0 Lustre 2.1.2 Lustre 1.8.8 0 3 <p>I found the source of this problem: an out-of-date copied function in lustre_patchless_compat.h</p> <p>truncate_complete_page needs to handle cgroup appropriately, and the copy with its own ll_remove_from_page_cache does not. A call to mem_cgroup_uncharge_cache_page is needed but it is not exported, nor does it seem easy or sensible to copy into the Lustre tree.</p> <p>Looks like this has broken the back of the compatibility layer for truncate_complete_page? For now I exported truncate_complete_page from the kernel and in an initial test it seemed to have fixed the problem, and cgroup began working reliably.</p> <p>Bobijam</p> <p>Could you please look into this report?</p> <p>Thanks</p> <p>Peter</p> <p>Mark,</p> <p>Looks like 2.6.32.8 kernel exports delete_from_page_cache in mm/filemap.c (Mark, can you confirm that also?)which can do what ll_remove_from_page_cache and page_cache_release do.</p> <p>For new pachless client, we cannot patch client kernel code to export truncate_complete_page but can leverage already exported delete_from_page_cache to do the same job (uncharge cgroup accounting for the page).</p> <p>But 2.6.38.8 exports another cgroup aware function remove_from_page_cache which do what ll_remove_from_page_cache does while rhel6 kernel does not export this function, it seems kernel has not settled down for this part which makes patchless client support difficult.</p> <p>patch tracking at <a href="http://review.whamcloud.com/1399" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/1399</a></p> <p>Integrated in <span class="image-wrap" style=""><img src="http://build.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black" /></span> <a href="http://build.whamcloud.com/job/lustre-master/./arch=i686,build_type=client,distro=el6,ib_stack=inkernel/338/" class="external-link" target="_blank" rel="nofollow noopener">lustre-master » i686,client,el6,inkernel #338</a><br/> <a href="https://jira.whamcloud.com/browse/LU-620" title="&quot;Bad page state&quot;
