Hi Casey,
Thanks. I even got a compiling error with fio-objectstore branch.
Here is error message:
make[3]: *** No rule to make target `rbd_fuse/rbd-fuse.c', needed by `rbd_fuse/rbd-fuse.o'. Stop.
make[3]: *** Waiting for unfinished jobs....

jamesliu@jamesliu-OptiPlex-7010:~/WorkSpace/ceph_fio$ git branch

James

Hi James,
I'm sorry for not following up on that segfault, but I wasn't ever able to reproduce it. I used it recently for memstore testing without any problems. I wonder if there's a problem with the autotools build? I've only tested it with cmake. When I find some time, I'll rebase it on master and do another round of testing.
Casey
