In our PVE cluster have 5 hosts with ceph storage on all hosts disks. I setup backups to save on Synology with NFS storage. For 2-3 moths right now backups load very long time and not fast to finish backup from all hosts. If we change the MTU from default 1500 on Synology and on hosts to 9000 MTU is possible to make it fast. Synology and the hosts connect to the Fiber Optic 10GB switch but the mtu on switch and on the hosts for now is default. If I ping to Synology from hosts : ping -s 9000 -d 192.168.8.23 PING 192.168.8.23 (192.168.8.23) 9000(9028) bytes of data. 9008 bytes from 192.168.8.23: icmp_seq=1 ttl=63 time=1.03 ms 9008 bytes from 192.168.8.23: icmp_seq=2 ttl=63 time=0.223 ms 9008 bytes from 192.168.8.23: icmp_seq=3 ttl=63 time=0.229 ms I have the answer.

Can some one give me suggestion  how I can make faster the NFS backup on hosts (all hosts is now production). -- Sergey TS The best Regard _______________________________________________ pve-user mailing list pve-user@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
