Description

In 24 hours DNE failover test. I found this on one of the MDT,

LustreError: 2758:0:(client.c:2869:ptlrpc_replay_interpret()) @@@ status -110, old was 0  req@ffff880feb148cc0 x1507974808149044/t25771723485(25771723485) o1000->lustre-MDT0003-osp-MDT0001@192.168.2.128@o2ib:24/4 lens 248/16576 e 1 to 0 dl 1438129486 ref 2 fl Interpret:R/4/0 rc -110/-110

Then on the client side, which cause dbench fails

Then the test fails.
