          Thanks for confirming Hongchao. Ok so then we do not need to land it to more current releases and I will close the ticket.

          Hi, this patch isn't needed for SLES11 SP3.

          Thanks Rajesh. My concern is that this patch has not yet been landed to newer versions of Lustre so if the customer were to upgrade it might mean that this issue reoccurs for them.

          Hongchao

          This fix was for SLES11 SP2 clients. Is it still necessary for SLES11 SP3 clients which is what is supported on master and b2_5? If so, please could you push this fix firstly against master to get it finalized and landed. If this issue is specific to SLES11 SP2 only then I agree that it is ok to mark the ticket as Resolved.

          Thanks

          We have upgraded both server side and client side.

          1. On the server side customer upgraded into 2.4.3 with the Patch

          And now they don't see the issue, and it can be closed.

          To be clear, do you mean upgraded to a newer Lustre version or upgraded to use the patch supplied?

          We can close this LU. Customer had upgraded the Server and Clients and they don't see this issue.
