<pre wrap="">our lustre installation uses two failover MDSes, which serve 10
file-systems. We recently upgraded from 1.8.1.1 to 1.8.2 version.
By monitoring the MDSes I noticed that we get frequent error messages
(1-4 times/hour) which looklike this:

<pre wrap="">This likely means some client was evicted in the past, but later on it
is closing a file that was previously opened. This is not an error to
be concerned about, and we should probably just turn it off.

<pre wrap="">You can find which client this is via (something like, I'm not logged on
my system):
lfs get_param mds.*.exports.*.uuid | grep 60822f67-b798-f355-

<pre wrap=""><!---->
lctl get_param mds.*.exports.*.uuid | grep 60822f67-b798-f355-
d5b1-54d7d7fa9f15
worked fine. This command provides info about the server and the client.
Is there any way to get information about the file of the error message?

You can actually see the inode number in the message:<br>
<br>
<pre wrap="">31386:0:(mds_open.c:1666:mds_close()) @@@ no handle for file close ino
4011004: cookie 0x699184f2b7f715d6 req@ffff8100621d2c00

is the inode number.<br>

I would like to ask:
a) is this a critical error message?
b) is there any way to find out more info about it. e.g. filesystem,
filename and lustre client that are related to this error?
c) is there any way to resolve this errors?
