[LU-5455] Get EIO errors when loading lustre modules fails

Wed, 18 Feb 2015 23:07:03 +0000

when running command 'modprobe lustre', it output following error messages:

modprobe: ERROR: could not insert 'lustre': Input/output error

kernel error messages are:
[ 688.834915] LNetError: 2502:0:(linux-tcpip.c:162:libcfs_ipif_enumerate()) Error -515 enumerating interfaces
[ 688.834919] LNetError: 2502:0:(socklnd.c:2617:ksocknal_enumerate_interfaces()) Can't enumerate interfaces: -515
[ 689.836129] LNetError: 105-4: Error -100 starting up LNI tcp
[ 689.836258] LustreError: 2502:0:(events.c:566:ptlrpc_init_portals()) network initialization failed

So the problem is that it is because we fail to init network, but EIO here is a little confusing for common users.

Since error handling has been there, after returning error code to the caller, rerun 'mod probe lustre', it output messages like:

modprobe: ERROR: could not insert 'lustre': Network is down
