We recently upgraded from 1.4.10.1 to 1.6.5.1 (clients and servers)
and now we are seeing errors like
Aug 27 07:49:54 oss025 kernel: LustreError: 3738:0:(ost_handler.c:
1163:ost_brw_write()) client csum 2dbc1696, server csum 9d081697
Aug 27 07:49:54 oss025 kernel: LustreError: 168-f: p1-OST0018: BAD
WRITE CHECKSUM: changed in transit before arrival at OST from
12345-172.16.4.93 at tcp inum 24522277/426969871 object 12021/0 extent
[10485760-11534335]
Aug 27 07:49:55 oss025 kernel: LustreError: 3738:0:(ost_handler.c:
1225:ost_brw_write()) client csum 2dbc1696, original server csum
9d081697, server csum now 9d081697
always from the same cluster node... Should we be worried? I suspect
this means we shouldn't turn check summing off? I assume these are
rejected and resent from the client?
