I'm upgrading from Giant to Hammer (0.94.1), and I'm seeing a ton of OSDs die (and stay dead) with this error in the logs:
2015-04-19 11:53:36.796847 7f61fa900900 -1 osd/OSD.h: In function 'OSDMapRef OSDService::get_map(epoch_t)' thread 7f61fa900900 time 2015-04-19 11:53:36.794951 osd/OSD.h: 716: FAILED assert(ret) ceph version 0.94.1 (e4bfad3a3c51054df7e537a724c8d0bf9be972ff) 1: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x8b) [0xbc271b] 2: (OSDService::get_map(unsigned int)+0x3f) [0x70923f] 3: (OSD::load_pgs()+0x1769) [0x6c35d9] 4: (OSD::init()+0x71f) [0x6c4c7f] 5: (main()+0x2860) [0x651fc0] 6: (__libc_start_main()+0xf5) [0x7f61f7a3fec5] 7: /usr/bin/ceph-osd() [0x66aff7] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. This is on a small cluster, with ~40 OSDs on 5 servers running Ubuntu 14.04. So far, every single server that I've upgraded has had at least one disk that has failed to restart with this error, and one has had several disks in this state. Restarting the OSD after it dies with this doesn't help. I haven't lost any data through this due to my slow rollout, but it's really annoying. Here are two full logs from OSDs on two different machines: https://dl.dropboxusercontent.com/u/104949139/ceph-osd.25.log https://dl.dropboxusercontent.com/u/104949139/ceph-osd.34.log Any suggestions?
