Upstart osd #20

add files to use osd with upstart

guilhem · 2012-09-20T14:22:21Z

any news ?

tv42 · 2012-09-21T03:25:18Z

The osds are started by the ceph-hotplug job, which detects disks that have been prepared with ceph-disk-prepare. I do not intend to have people editing their /etc/fstab for osds, that would be a lot of trouble for something that can be automated this easily.

Two weeks without response -> assuming this is ok. Let me know if you're unhappy.

Hi,

Yes I understand this point of view and I will change my infrastructure to be sync with this (good) method.

Thank you.

Best Regards.

before this change, we increment the refcount when constructing `cct` instrusive_ptr, but nobody owns this smart pointer. also, `CephContext` 's constructor set its refcount to 1. so, when the test finishes, the refcount is 1, and this leads to a leakage of the `CephContext` instance. and LeakSanitizer points this out: ``` Indirect leak of 10880000 byte(s) in 1 object(s) allocated from: #0 0x558d341d837d in operator new(unsigned long) (/home/jenkins-build/build/workspace/ceph-pull-requests/build/bin/unittest_ipaddr+0x19b37d) (BuildId: 1b7e7e5abfc2b58ce2334712e4c00b2441c25870) ceph#1 0x7fd74c957559 in __gnu_cxx::new_allocator<ceph::logging::ConcreteEntry>::allocate(unsigned long, void const*) /usr/bin/../lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/ext/new_allocator.h:127:27 ceph#2 0x7fd74c956933 in std::allocator<ceph::logging::ConcreteEntry>::allocate(unsigned long) /usr/bin/../lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/bits/allocator.h:185:32 ceph#3 0x7fd74c956933 in boost::circular_buffer<ceph::logging::ConcreteEntry, std::allocator<ceph::logging::ConcreteEntry> >::allocate(unsigned long) /opt/ceph/include/boost/circular_buffer/base.hpp:2396:39 ceph#4 0x7fd74c956690 in boost::circular_buffer<ceph::logging::ConcreteEntry, std::allocator<ceph::logging::ConcreteEntry> >::initialize_buffer(unsigned long) /opt/ceph/include/boost/circular_buffer/base.hpp:2494:18 ceph#5 0x7fd74c950562 in boost::circular_buffer<ceph::logging::ConcreteEntry, std::allocator<ceph::logging::ConcreteEntry> >::circular_buffer(unsigned long, std::allocator<ceph::logging::ConcreteEntry> const&) /opt/ceph/include/boost/circ ular_buffer/base.hpp:1039:9 ceph#6 0x7fd74c9435b4 in ceph::logging::Log::Log(ceph::logging::SubsystemMap const*) /home/jenkins-build/build/workspace/ceph-pull-requests/src/log/Log.cc:53:5 ceph#7 0x7fd74bc1891d in ceph::common::CephContext::CephContext(unsigned int, ceph::common::CephContext::create_options const&) /home/jenkins-build/build/workspace/ceph-pull-requests/src/common/ceph_context.cc:729:16 ceph#8 0x7fd74bc178eb in ceph::common::CephContext::CephContext(unsigned int, code_environment_t, int) /home/jenkins-build/build/workspace/ceph-pull-requests/src/common/ceph_context.cc:697:5 ceph#9 0x558d341f97e9 in pick_address_filtering_Test::TestBody() /home/jenkins-build/build/workspace/ceph-pull-requests/src/test/test_ipaddr.cc:774:47 ceph#10 0x558d3430c4f6 in void testing::internal::HandleSehExceptionsInMethodIfSupported<testing::Test, void>(testing::Test*, void (testing::Test::*)(), char const*) /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2605:10 ceph#11 0x558d342c3fc2 in void testing::internal::HandleExceptionsInMethodIfSupported<testing::Test, void>(testing::Test*, void (testing::Test::*)(), char const*) /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2641:14 ceph#12 0x558d342749dc in testing::Test::Run() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2680:5 ceph#13 0x558d34276a12 in testing::TestInfo::Run() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2858:11 ceph#14 0x558d3427804b in testing::TestSuite::Run() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:3012:28 ceph#15 0x558d342954d8 in testing::internal::UnitTestImpl::RunAllTests() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:5723:44 ceph#16 0x558d34314d26 in bool testing::internal::HandleSehExceptionsInMethodIfSupported<testing::internal::UnitTestImpl, bool>(testing::internal::UnitTestImpl*, bool (testing::internal::UnitTestImpl::*)(), char const*) /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2605:10 ceph#17 0x558d342ca932 in bool testing::internal::HandleExceptionsInMethodIfSupported<testing::internal::UnitTestImpl, bool>(testing::internal::UnitTestImpl*, bool (testing::internal::UnitTestImpl::*)(), char const*) /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:2641:14 ceph#18 0x558d34294862 in testing::UnitTest::Run() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/src/gtest.cc:5306:10 ceph#19 0x558d34218d80 in RUN_ALL_TESTS() /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googletest/include/gtest/gtest.h:2486:46 ceph#20 0x558d34218d11 in main /home/jenkins-build/build/workspace/ceph-pull-requests/src/googletest/googlemock/src/gmock_main.cc:70:10 ceph#21 0x7fd749331d8f in __libc_start_call_main csu/../sysdeps/nptl/libc_start_call_main.h:58:16 ``` so, in this change, we do not increase the refcount when creating cct.

allocate memory and release the old one once there is insufficient memory which causing the old one to be invalid. So streambuf's data pointer and insertion position should be updated to newly allocated memory's address in vec.

allocate memory and release the old one once there is insufficient memory which causing the old one to be invalid. So streambuf's data pointer and insertion position should be updated to newly allocated memory's address in vec.
