Hello Somnath, I tried that and it seems to be loading librados.so.2.0.0 in both cases (client and cluster machine).
Thanks, Aakanksha From: Somnath Roy [mailto:Somnath.Roy@xxxxxxxxxxx]
Just make sure with tool like ‘lsof’ or so that ceph commands are loading the proper librados/librbd binaries by running say ‘ceph –w’… It should be loading hammer version of librbd/librados.. From: Aakanksha Pudipeddi-SSI [mailto:aakanksha.pu@xxxxxxxxxxxxxxx]
Hello Somnath, Thanks for the quick response! I checked the versions on the client and the cluster machine. They actually had different versions of ceph installed: 0.94.2 on the cluster and 0.80.9 on the client. I made changes
so that both of them have the same version of Ceph now. As for the librbd, librados packages, they seem to be having the same packages: librbd-dev, librbd1, librados2 and a few others. Is there any other way I could cross check? Thanks, Aakanksha From: Somnath Roy [mailto:Somnath.Roy@xxxxxxxxxxx]
There is probably a binary version mismatch (?)…Make sure rbd command is loading the proper librbd/librados binaries…

On Behalf Of Aakanksha Pudipeddi-SSI Hi, I am trying to create a Ceph block device on a ceph cluster machine itself for experimental purposes. I used to be able to do that earlier but it gives me a segmentation fault right now: *** Caught signal (Segmentation fault) ** in thread 7f49628f6840 ceph version 0.94.2 (5fb85614ca8f354284c713a2f9c610860720bbf3) 1: rbd() [0x595ffa] 2: (()+0x10340) [0x7f495cffc340] 3: (std::string::compare(char const*) const+0x1e) [0x7f495c21a17e] 4: (()+0x2d11e2) [0x7f495d6f11e2] 5: (()+0xa6c16) [0x7f495d4c6c16] 6: (main()+0x2952) [0x4c1132] 7: (__libc_start_main()+0xf5) [0x7f495b89fec5] 8: rbd() [0x4c6ee7] 2015-08-04 16:53:49.656920 7f49628f6840 -1 *** Caught signal (Segmentation fault) ** in thread 7f49628f6840 --- begin dump of recent events --- -15> 2015-08-04 17:00:00.719905 7fce88413840 5 asok(0x327ed80) register_command perfcounters_dump hook 0x3280ef0 -14> 2015-08-04 17:00:00.719922 7fce88413840 5 asok(0x327ed80) register_command 1 hook 0x3280ef0 -13> 2015-08-04 17:00:00.719925 7fce88413840 5 asok(0x327ed80) register_command perf dump hook 0x3280ef0 -12> 2015-08-04 17:00:00.719928 7fce88413840 5 asok(0x327ed80) register_command perfcounters_schema hook 0x3280ef0 -11> 2015-08-04 17:00:00.719931 7fce88413840 5 asok(0x327ed80) register_command 2 hook 0x3280ef0 -10> 2015-08-04 17:00:00.719932 7fce88413840 5 asok(0x327ed80) register_command perf schema hook 0x3280ef0 -9> 2015-08-04 17:00:00.719938 7fce88413840 5 asok(0x327ed80) register_command perf reset hook 0x3280ef0 -8> 2015-08-04 17:00:00.719941 7fce88413840 5 asok(0x327ed80) register_command config show hook 0x3280ef0 -7> 2015-08-04 17:00:00.719942 7fce88413840 5 asok(0x327ed80) register_command config set hook 0x3280ef0 -6> 2015-08-04 17:00:00.719946 7fce88413840 5 asok(0x327ed80) register_command config get hook 0x3280ef0 -5> 2015-08-04 17:00:00.719947 7fce88413840 5 asok(0x327ed80) register_command config diff hook 0x3280ef0 -4> 2015-08-04 17:00:00.719950 7fce88413840 5 asok(0x327ed80) register_command log flush hook 0x3280ef0 -3> 2015-08-04 17:00:00.719951 7fce88413840 5 asok(0x327ed80) register_command log dump hook 0x3280ef0 -2> 2015-08-04 17:00:00.719954 7fce88413840 5 asok(0x327ed80) register_command log reopen hook 0x3280ef0 -1> 2015-08-04 17:00:00.722884 7fce88413840 10 monclient(hunting): build_initial_monmap 0> 2015-08-04 17:00:00.723176 7fce88413840 -1 *** Caught signal (Segmentation fault) ** in thread 7fce88413840 Could anybody help me out here?
