Hello, Sorry if this as already been answered : I check the archives and found similar issues with DRBD8 but none with linstor and DRBD9.
This is not really a 'problem' but more a config/performance misconfig : when I 'move' a ressource from another storage backend to linstor storage on Proxmox, the sync is maxed at 3MB/s (completely flat). Drbdtop reports this : Sent: total:23.8MiB Per/Sec:3.0MiB Let me first confirm my hardware is (hopefully) capable of doing far more (10Gbps network and full SSD ZFS storage with nvme cache). So it seems I made a misconf somewhere. I tried to change a few values : # linstor controller drbd-options --max-buffers=36864 --rcvbuf-size=2097152 --sndbuf-size=1048576 # linstor controller drbd-options --c-fill-target=10240 --c-max-rate=737280 --c-min-rate=20480 --c-plan-ahead=10 That was described as optimal for 10Gbps network on some howtos I found. Just in case it wasn't applied on the fly, I ran drbdadm adjust on the resource (both nodes). Values are stored in /var/lib/linstor.d/linstor_common.conf file. No speed change in this sync. If I run 2 similar syncs at the same time, each of them is stuck at 3MB/s. What did I miss ?
