Hi! We are evaluating orangefs 2.8.6 with QDR-Infiniband on rocks cluster suite 6.0 (based on CentOS 6.x) and I have set up 8 Nodes (doppler14-20 and doppler22). Each node is metaserver, storageserver and client.
Connection is made via ib://doppler18:3335/pvfs2-fs. The file system is mounted to /scratchfs via the kernel-inteface (pvfs2.ko). Our kernel version is "2.6.32-220.13.1.el6.x86_64" We have very impressive transfer rates (with 800-600MB/s) when we dump very big files (1TB) on the filesystem (dd if=/dev/zero of=/scratchfs/testfile.dump bs=8192K) , but when reading the dump to /dev/zero the client-core collapses and our /scratchfs gets inaccessible. The use of pvfs2fuse does not improve the situation, since we get a socket error (usually after dumping of 1GB of data, sometimes earlier, sometimes later ..). The pvfs2fuse-mountpoint gets also inaccessible . I've found this in one of our client log files: ".. [E 14:22:23.279365] Error: encourage_recv_incoming: mop_id 7f6ce4000950 in RTS_DONE message not found. [E 14:22:23.292947] [bt] pvfs2-client-core(error+0xca) [0x46f91a] [E 14:22:23.292978] [bt] pvfs2-client-core() [0x46ccc4] [E 14:22:23.292999] [bt] pvfs2-client-core() [0x46ea65] [E 14:22:23.293018] [bt] pvfs2-client-core(BMI_testcontext+0xf3) [0x45aa83] [E 14:22:23.293037] [bt] pvfs2-client-core(PINT_thread_mgr_bmi_push+0x159) [0x4608a9] [E 14:22:23.293056] [bt] pvfs2-client-core() [0x45c9aa] [E 14:22:23.293074] [bt] pvfs2-client-core(job_testcontext+0x12a) [0x45d19a] [E 14:22:23.293092] [bt] pvfs2-client-core(PINT_client_state_machine_testsome+0xee) [0x41757e] [E 14:22:23.293111] [bt] pvfs2-client-core() [0x412ecd] [E 14:22:23.293130] [bt] pvfs2-client-core(main+0x703) [0x413fb3] [E 14:22:23.293165] [bt] /lib64/libc.so.6(__libc_start_main+0xfd) [0x392b41ecdd] [E 14:22:23.303725] pvfs2-client-core with pid 29108 exited with value 1 .." I have ot found any evidence for this error in the server log files though .. This is the output of our /etc/pvfs2tab: "ib://doppler18:3335/pvfs2-fs /scratchfs pvfs2 defaults,noauto 0 0" Please can you help me to stabilize the read access to our files ?
