Hi, As an update, over many days there has not been any change in the rate of successful jobs with the block sizes at 64MB as suggested by @wyang007 . I note though that the changes were applied only on the test WNs. However, we see CEPH as performing normally. So it is not clear to me if there is a reason to apply it to the whole batch farm to see an effect. @Tom-Byrne is waiting for the CE to come back after upgrading to get the tracing with timestamp information for a running job. Regards, Raja. -- You are receiving this because you were mentioned.
