hi gperf-tools v2.5.93 (or fc25 users), we sync'ed rocksdb to the recent upstream version in master last week-end. if you are using gperf-tools 2.5.93 (which is shipped with fc25), then you are likely to hit http://tracker.ceph.com/issues/21422. the root cause is that tcmalloc is offered by gperf-tools. but gperf-tools v2.5.93 didn't implement aligned_alloc(), and the recent version of rocksdb is using it. so what gets called is the glibc's aligned_alloc(), and when rocksdb frees that memory chunk allocated by aligned_alloc(), the free() from tcmalloc is used. so it panic'ed. for more details, please refer to the tracker ticket[0] and the pull request[1] to address it. if you compile the latest master of ceph using gperf-tools 2.5.93, you will get Incompatible tcmalloc v2.5.93 and rocksdb v5.8.0, please install gperf-tools 2.5 or > 2.6.2". since the latest release of gperf-tools is 2.6.1, and it has not yet cut a release after including the for the aligned_alloc(), currently the suggested way to fix it is to upgrade your gperf-tools to the latest master by installing it[3] manually. and point cmake to it: $ ./configure --prefix=$HOME/local # under gperftools $ make install $ GPERF_ROOT=$HOME/local cmake .. # under ceph/build --- [0] http://tracker.ceph.com/issues/21422 [1] https://github.com/ceph/ceph/pull/17788 [3] https://github.com/gperftools/gperftools/tree/master -- Regards Kefu Chai -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
