[Lustre-discuss] strange lustre errors

[Balagopal Pillai]

Hi,

             On a few of the hpc cluster nodes, i am seeing a new lustre 
error that is pasted below. The volumes are working fine and there
is nothing on the oss and mds to report.


LustreError: 5080:0:(import.c:607:ptlrpc_connect_interpret()) 
data3-OST0000_UUID at 192.168.2.98@tcp changed handle from 
0xfe51139158c64fae to 0xfe511392a35878b3; copying, but this may 
foreshadow disaster

                Any help in interpreting these error messages is much 
appreciated. The two lustre oss/mds/mgs servers have been running fine 
with an uptime for over a month now after the ldiskfs patch is applied 
as mentioned here -
https://bugzilla.lustre.org/show_bug.cgi?id=13438

              The version of Lustre is 1.6.3.


Thanks
