search for: obd_health_check

...rm, the code is: LCONSOLE_ERROR_MSG(0x11, "%s Communicating with %s") in ptlrpc_check_status(). There''s another in mdt_obd_connect() where -EAGAIN [set to -11 in lustre_errno.h) is returned if the stack isn''t ready to handle requests as indicated by the return code from obd_health_check(). My environment is this: MDT, OSS0, and OSS1 are all on 3 separate nodes running Centos 6.4 and connected by Infiniband Mellanox HBAs. Running this in a VM with the MDT and a single OSS on one node in a VM using TCP did not exhibit this problem. Thanks in advance for any help you can provide....
