I've also removed libgoogle-perf and reinstalled, but still the same error, so I followed your suggestion, I've removed that line in cosd, and as well as cmds, now it compiles and seems working. Just unsure why IsHeapProfilerRunning is not detected? Also, I'm still getting the terrible performance, running dbench -t20 20 shows 11MB/s. I've also tried on other disks, too. Do you think it is because the Fuse does not have -o direct_io or big_writes support? Setting the journal wasn't much of difference, something seems to be fundamentally slow. Again, I'm running on the simplest setup, just 1OSD (1TB), 1MDS, 1MON. all following the quick start guide. How do others get in their performance? Also, I keep getting unknown freezes when benchmarking and file copying. So this time, I've set everything on a single high-end rackmount, ubuntu 10.04.1 x64. Maybe this could be due to the 2.6.32 kernel, so I decided update to 2.6.35.7. I'd thought that the ceph-client would be there by default, but the somehow ceph mount hangs, so I just git the latest ceph-client-standalone, set to the master and did the make. I get WARNING: "account_page_dirtied" [/home/aaa/ceph/ceph-client-standalone/ceph.ko] undefined! LD [M] /home/aaa/ceph/ceph-client-standalone/ceph.ko make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-02063507-generic' So when I tried to modprobe ceph, I get FATAL: Error inserting ceph (/lib/modules/2.6.35-02063507-generic/extra/ceph.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg just shows "ceph: Unknown symbol account_page_dirtied (err 0)" For "unstable" branch, I get lots of errors starting from make[1]: Entering directory `/usr/src/linux-headers-2.6.35-02063507-generic' CC [M] /home/aaa/ceph/ceph-client-standalone/super.o /home/aaa/ceph/ceph-client-standalone/super.c:2:35: error: linux/ceph/ceph_debug.h: No such file or directory In file included from /home/aaa/ceph/ceph-client-standalone/super.c:18: /home/aaa/ceph/ceph-client-standalone/super.h:17:32: error: linux/ceph/libceph.h: No such file or directory In file included from /home/aaa/ceph/ceph-client-standalone/super.c:18: /home/aaa/ceph/ceph-client-standalone/super.h: In function ‘ceph_put_cap_snap’: /home/aaa/ceph/ceph-client-standalone/super.h:153: error: implicit declaration of function ‘ceph_buffer_put’ /home/aaa/ceph/ceph-client-standalone/super.h: At top level: /home/aaa/ceph/ceph-client-standalone/super.h:234: error: field ‘i_vino’ has incomplete type ... unstable-backport is the only thing that seems to modprobed, however it gives "failed to parse ceph_options" when I tried to mount.. Thank a lot.
