@stgraber I tried to overmount as you described. The overmount works but lxc copy (snapd lxd) would fail instantly complaining about missing linked libraries. It appears snap running a non-snap rsync breaks library links since it can’t find them in the snaps env.
Pretty much isolated glass ceiling of lxc copy to rsync and I just need a fast way to verify it.
- Ubuntu 22.04
- 5.19 custom kernel
- MTU 9000
- iperf3 verified 37Gb/s bidirectional over 40G nic.
- fio verified 1000MB+ read/write speed on local pcie4 nvme.
- Snapd lxd latest stable
- rsync.compression off in lxc storage
- amd zen3 cpu
Even with above config, lxc copy between the two machines, large database files, can only muster 3Gb/s max transfer speed or around 375MB/s
What is the easiest way for me to inject a distro default (optimzied) rsync into lxd for testing? I can compile lxd if needs be.
Thanks.
