Subject: [PVE-User] NFS Backups
Date: Wed, 20 Jul 2022 12:12:18 +0300 [thread overview]
Message-ID: <b96ab9ea-fdf8-409c-6c8a-088190c0b0f2@t8.ru> (raw)
Hi, to all.
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.
When I test connection with between the hosts PVE connect :
iperf3 -c 10.10.29.16
Connecting to host 10.10.29.16, port 5201
[ 5] local 10.10.29.10 port 51502 connected to 10.10.29.16 port 5201

But the speed to backup to NFS is very low.
Can some one give me suggestion how I can make faster the NFS backup on
hosts (all hosts is now production).
