The move seems to work as expected on recent kernels. I get O(1) with this version:
# uname -r 5.9.9-1.el7.elrepo.x86_64 I cannot upgrade on the machine I need to do the move on. Is it worth trying a newer fuse client, say from the nautilus or octupus repo?

I was told that the fuse client does not have this problem. If enough space is available, a move should be a move, not a copy. Today, I tried to move a large file across quota domains testing botn, the kernel- and the fuse client. Both still resort to a copy even though this issue was addressed quite a while ago (https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/44AEIHNEGKV4VGCARRTARGFZ264CR4T7/#XY7ZCE3KWHI4QSUNZHDWL3QZQFOHXRQW). The versions I'm using are (CentOS 7) # yum list installed | grep ceph-fuse ceph-fuse.x86_64 2:13.2.10-0.el7 @ceph # uname -r 3.10.0-1160.31.1.el7.x86_64 Any suggestions how to get this to work? I have to move directories containing 100+ TB.
