I think you should use the kernel provided with proxmox, package pve-kernel-xxx

I use influxdb to collect data and Grafana to display https://pve.proxmox.com/wiki/External_Metric_Server

You could use LVM-thin or ZFS to have snapshot and other features of qcow2

Have you tried with virtio or virtio-scsi drivers instead of IDE (very slow driver). What is the file system of the proxmox host?

Have you enabled UDP in influxdb.conf ?

If your InfluxDB listening on UDP? In my /etc/influxdb/influxdb.conf ..... [[udp]] enabled = true bind-address = ":8089" database = "proxmox" log-enabled = false ..... And don't forget to create the database, from the machine with influxdb: $ influx Visit...

If you are using VirtIO drivers for disk, try changing to SCSI, just remember to install vioscsi driver in Windows before.

It's the same for me. I have a cluster with 2 pfSense VMs with CARP configuration (master/backup) and if I don't disable hardware checksum offload in pfSense I have huge problems with network. Disabling it and using VirtIO drivers, the two pfSense boxes work great.

You have two alternatives: - use shared storage - use ZFS in both nodes and use replication

From /etc/apt/sources.list.d remove pve-enterprise.list then apt update && apt dist-upgrade

No partition on that disk /dev/sdb? What file system are you using?

You can click in the second disk and choose none, so it will install only in the first disk as ZFS raid0 You are running proxmox inside VMware, is it a test environment?

Do you have some files in /etc/apt/sources.list.d/ ? It seems that you have some apt source with jessie in it, that must be removed

remove or comment lines in file /etc/apt/sources.list.d/pve-enterprise.list

Ok, thanks. The interval of 60 seconds is ok for me, so I'll change the timespan in the graphs. Thank you very much

I'm not a CEPH expert, I run a little CEPH cluster not so different from yours (3 nodes, 3x1TB HDD + 1x250GB SSD in each node), what I have learnt is that too much PGs in each OSD will be bad for performance and data distribution. So if you plan a CEPH cluster with 2 OSDs per node, 3 nodes...

IMHO two OSDs per node are a bit few, however it's working. CEPH in the crushmap have the failure domain (it's related to the rule), that usually is the host. So each PG is replicated <size> number of times across different hosts. But I strongly advice you against size=2. I read a lot of...

ZFS RAID 1 with the two SSDs, install proxmox on that and use that (local-zfs) for VM disks that need fast storage. Then ZFS RAID 1+0 with the four spinners, add the new pool as storage on proxmox and use that for VM disks that are ok with a slower storage (small or seldom used datas, and so on)...

Thanks for your reply. I just added the transformation as you said and now the graph is working as it should, the last problem is that values I see in the Grafana graph are different from the values I see in the Proxmox GUI in the same time range. Look at examples: This is the graph of disk...

Hello. Following the guide at https://pve.proxmox.com/wiki/External_Metric_Server I configured my proxmox servers to send status data to an influxdb server, it's working and I can see nodes measurements and VM/LXC measurements, graphing them in grafana with influxdb data source. But I can't...
