Hi all, I used v0.22.2 ceph with latest git "ceph-standalone-client kernel" (2.6.36-rc8) and when i try to mount i get the following error mount error 5 = Input/output error the dmesg call trace is as follows: [ 199.099511] ceph: loaded (mds proto 32) [ 227.730778] libceph: client4099 fsid 2bf77910-49e4-89cb-8ef0-b74ce321acc4 [ 227.730999] libceph: mon0 192.168.1.79:6789 session established [ 360.236062] INFO: task cosd:5004 blocked for more than 120 seconds.

I got the same error with v0.22.2 and kernel 2.6.35 . So i updated the kernel but it didn't help. In ceph code , in src/cmds.cc and src/cosd.cc i commented out the line // g_conf.profiler_running = IsHeapProfilerRunning; for the compilation to pass. the steps i used the following commands as root: mkcephfs -c /etc/ceph/ceph.conf --allhosts -v /etc/init.d/ceph -a start modprobe ceph mount -t ceph 192.168.1.79:/ /ceph Kindly point out what i am missing. thanks, mugunthan
