Hello Amudhan, What does exactly mean "it takes < 250KB/s"? I figured out this discussion between you and Kotresh: https://lists.gluster.org/pipermail/gluster-users/2016-September/028354.html Kotresh mentioned there that the problem is because for some files fd process are still up in the brick process list. Bitrot signer can only sign a file if the fd is closed. And according to my observations it seems to be that as bigger a file is as longer the fd is still up. I could verify this with a 500MiB file and some smaller files. After a specific time only the fd for the 500MiB was up and the file still had no signature, for the smaller files there were no fds and they already had a signature.
Does anybody know what is the reason for this? For me it looks loke a bug. Regards David Am Fr., 1.
