[Lustre-discuss] LustreError codes -114 and -16 (ldlm_lib.c:1919:target_send_reply_msg())

[Marina Cacciagrano]

Thanks! 
Maybe that means that the drives are a bit too slow to respond to the requests... 
Can that be related to a problem with lnet as well?

errno 16 is EBUSY (device or resource busy) and errno 114 is EALREADY (Operation already in progress).

Hello, 
On all the nodes of a lustre 1.8.2 , I often see messages similar to the following in /var/log/syslog: 
LustreError: 8862:0:(ldlm_lib.c:1919:target_send_reply_msg()) @@@ processing error (-114) req at ffff8103f97dc850 x1393780295030087/t0 o250->bfd79683-ce51-1e18-7f40-632c3a616b01 at NET_0x20000ac1054d2_UUID:0/0 lens 368/264 e 0 to 0 dl 1329235090 ref 1 fl Interpret:/0/0 rc -114/0 
and 
LustreError: 8963:0:(ldlm_lib.c:1919:target_send_reply_msg()) @@@ processing error (-16) req at ffff81024b636400 x1393871458142225/t0 o38->e3e2f978-3cc1-c6f9-17cb-9ac846be7fae at NET_0x20000ac1138c2_UUID:0/0 lens 368/264 e 0 to 0 dl 1329300007 ref 1 fl Interpret:/0/0 rc -16/0 

I cannot find the meaning of error codes -144 and -16. 
Can anybody advise on what generates those errors? 

A quick description of the configuration: 
the lustre version is 1.8.2. 
the system is made up by one MDS host and seven OSS hosts. 
lnet is over 10Ge. 


Regards, 
marina
