Description

The customer saw the following error messages on MDS during 128 clients were creating the many small files. (mostly 1 milion files), then they also saw Input/output error to the some files, when they opened these files.

(lov_request.c:690:lov_update_create_set()) error creating fid xxx rc=-107

As far as we see the log files on OSSs, at the same time, there are many slow IO messages at the same time.

-107 = -ENOTCONN, is this happened connection loss between server and client? (MDS to OSS as well?)

Please advise.
