[ceph-users] osdmap::decode crc error -- 13.2.7 -- most osds down

Hi, My turn. We suddenly have a big outage which is similar/identical to http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-August/036519.html Some of the osds are runnable, but most crash when they start -- crc error in osdmap::decode. I'm able to extract an osd map from a good osd and it decodes well with osdmaptool: # ceph-objectstore-tool --op get-osdmap --data-path /var/lib/ceph/osd/ceph-680/ --file osd.680.map But when I try on one of the bad osds I get: # ceph-objectstore-tool --op get-osdmap --data-path /var/lib/ceph/osd/ceph-666/ --file osd.666.map terminate called after throwing an instance of 'ceph::buffer::malformed_input' what(): buffer::malformed_input: bad crc, actual 822724616 != expected 2334082500 *** Caught signal (Aborted) ** in thread 7f600aa42d00 thread_name:ceph-objectstor ceph version 13.2.7 (71bd687b6e8b9424dd5e5974ed542595d8977416) mimic (stable) 1: (()+0xf5f0) [0x7f5ffefc45f0] 2: (gsignal()+0x37) [0x7f5ffdbae337] 3: (abort()+0x148) [0x7f5ffdbafa28] 4: (__gnu_cxx::__verbose_terminate_handler()+0x165) [0x7f5ffe4be7d5] 5: (()+0x5e746) [0x7f5ffe4bc746] 6: (()+0x5e773) [0x7f5ffe4bc773] 7: (()+0x5e993) [0x7f5ffe4bc993] 8: (OSDMap::decode(ceph::buffer::list::iterator&)+0x160e) [0x7f6000f4168e] 9: (OSDMap::decode(ceph::buffer::list&)+0x31) [0x7f6000f42e31] 10: (get_osdmap(ObjectStore*, unsigned int, OSDMap&, ceph::buffer::list&)+0x1d0) [0x55d30a489190] 11: (main()+0x5340) [0x55d30a3aae70] 12: (__libc_start_main()+0xf5) [0x7f5ffdb9a505] 13: (()+0x3a0f40) [0x55d30a483f40] Aborted (core dumped) I think I want to inject the osdmap, but can't: # ceph-objectstore-tool --op set-osdmap --data-path /var/lib/ceph/osd/ceph-666/ --file osd.680.map osdmap (#-1:b65b78ab:::osdmap.2983572:0#) does not exist. How do I do this? Thanks for any help! dan
