[Lustre-discuss] LustreError: server_bulk_callback

[Nathan Dauchy]

Greetings,

We have 4 OSS nodes and 2 MDS nodes configured in HA pairs, running
2.6.18-53.1.14.el5_lustre.1.6.5smp, and using the o2ib network
transport.  We had multiple failovers recently (possibly due to hardware
problems, but no root cause yet) and managed to get things back again to
what I _thought_ was a normal state.

However, in the system log we are seeing many "server_bulk_callback"
error messages at the rate of ~6 per second.  Interestingly, they only
come from one HA pair of OSS nodes:

Sep 24 23:03:14 lfs-oss-0-3 kernel: LustreError:
20694:0:(events.c:361:server_bulk_callback()) event type 4, status -103,
desc ffff81019fce6000

desc ffff81019fce6000
Sep 24 23:03:16 lfs-oss-0-2 kernel: LustreError:
27257:0:(events.c:361:server_bulk_callback()) event type 4, status -103,

Sep 24 23:03:16 lfs-oss-0-2 kernel: LustreError:
27257:0:(events.c:361:server_bulk_callback()) event type 2, status -103,
desc ffff8101b52b8000

Can anyone direct me to documentation to decipher these messages?
What does "server_bulk_callback" do, and does "status -103" indicate a
severe problem for event types 2 and 4?

Thanks very much for your guidance,
Nathan
