Hi, I've ugpraded tiny jewel cluster from 10.2.2 to 10.2.7 and now one of OSDs fails to start.. here's (hopefully) important part of the backtrace: 2017-05-01 19:54:17.627262 7fb2bbf78800 10 filestore(/var/lib/ceph/osd/ceph-1) stat meta/#-1:c0371625:::snapmapper:0# = 0 (size 0) 2017-05-01 19:54:17.627440 7fb2bbf78800 0 <cls> cls/hello/cls_hello.cc:305: loading cls_hello 2017-05-01 19:54:17.629044 7fb2bbf78800 0 <cls> cls/cephfs/cls_cephfs.cc:202: loading cephfs_size_scan 2017-05-01 19:54:17.630656 7fb2bbf78800 15 filestore(/var/lib/ceph/osd/ceph-1) read meta/#-1:3294e826:::osdmap.53:0# 0~0 2017-05-01 19:54:17.630674 7fb2bbf78800 10 filestore(/var/lib/ceph/osd/ceph-1) FileStore::read meta/#-1:3294e826:::osdmap.53:0# 0~0/0 terminate called after throwing an instance of 'ceph::buffer::end_of_buffer' what(): buffer::end_of_buffer *** Caught signal (Aborted) ** in thread 7fb2bbf78800 thread_name:ceph-osd ceph version 10.2.7 (50e863e0f4bc8f4b9e31156de690d765af245185) 1: (()+0x91d8ea) [0x5609e9f938ea] 2: (()+0xf370) [0x7fb2ba6ca370] 3: (gsignal()+0x37) [0x7fb2b8c8b1d7] 4: (abort()+0x148) [0x7fb2b8c8c8c8] 5: (__gnu_cxx::__verbose_terminate_handler()+0x165) [0x7fb2b958f9d5] 6: (()+0x5e946) [0x7fb2b958d946] 7: (()+0x5e973) [0x7fb2b958d973] 8: (()+0x5eb93) [0x7fb2b958db93] 9: (ceph::buffer::list::iterator_impl<false>::copy(unsigned int, char*)+0xa5) [0x5609ea09e425] 10: (OSDMap::decode(ceph::buffer::list::iterator&)+0x6d) [0x5609ea055a9d] 11: (OSDMap::decode(ceph::buffer::list&)+0x2e) [0x5609ea056d9e] 12: (OSDService::try_get_map(unsigned int)+0x4ac) [0x5609e9a0882c] 13: (OSDService::get_map(unsigned int)+0xe) [0x5609e9a6b5fe] 14: (OSD::init()+0x1fe2) [0x5609e9a1e782] 15: (main()+0x2c55) [0x5609e9981dc5] 16: (__libc_start_main()+0xf5) [0x7fb2b8c77b35] 17: (()+0x3561e7) [0x5609e99cc1e7] 2017-05-01 19:54:17.632871 7fb2bbf78800 -1 *** Caught signal (Aborted) ** in thread 7fb2bbf78800 thread_name:ceph-osd full osd log is here: http://nik.lbox.cz/download/osd-crash.txt I've found some older discussions and reports of similar problem, but none of current versions, especially 10.2.7 the cluster is very small (just 2+2 OSDs, 3 mons, no MDS), was installed as 10.2.2, therefore no upgrade from hammer or so.. OS is centos7 based, 4.4.52 x86_64 kernel.. If anyone is interested in it, I can provide more info if needed, otherwise I'll reformat OSD to get it back into OK state..
