Hi, guys, I'm using ceph nautilus in my production, the kernel clients include 5.4 and 4.15, I found a problem in 5.4 sometimes: It's slower than fuse, but when I changed it to 4.15, it's recovered. for 5.4: root@WXRG0432:/mnt/test# rsync -ahHv --progress /root/test test-1 sending incremental file list test 58.56M 5% 2.82MB/s 0:05:43 ^C for 4.15: root@WXRG0433:/mnt/test# rsync -ahHv --progress /root/test test-2 sending incremental file list test 1.05G 100% 316.25MB/s 0:00:03 (xfr#1, to-chk=0/1) sent 1.05G bytes received 35 bytes 299.67M bytes/sec Anyone have met the same problems with me?
