Yes, it is due to multicast. You need a solution that allows multicast to pass through your tunnel. Once you have that done, you also need a low latency connection between your cluster and your remote nodes. Else you might have issues of "node-flapping" which gets annoying fast. We do...

I typically use openvswitch in conjunction with my networking needs on Proxmox. See here: https://pve.proxmox.com/wiki/Open_vSwitch Unless you have hardware that allows you to properly apply QOS while using bonding (in which case I'd bond 2x10G for Ceph and 2x1G for Proxmox ), I'd switch to...

Any Chance your initial issue happened after an update ? If so, try this:

Afaik the way of the "web interface" is apt-get update (when you hit the refresh button) apt-get dist-upgrade (when you trigger an upgrade)

Please be advised that it is generally not advised to run a virtualized FreeNAS. However if you know what you are doing, where the pitfalls lie and that you are sure you still wanna go through with it, you probably wanna pass the 2 HDD's through to FreeNAS...

Afaik the last time i did this, i was following this example: https://pve.proxmox.com/wiki/Pci_passthrough#Determine_your_PCI_card_address.2C_and_configure_your_VM So I'd add this to your vm-config: hostpci0: 03:00 or I'd add: hostpci0: 0a:00 AFAIR (and I might be wrong here) you should...

I'd verify that the card you added is in fact the "Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06)" I'd then use that one for Proxmox and pass one of the other two which most likely are single Port onboard nics (or just present them self that way) through to the VM. (since these...

My post was not meant to be "look my number is right" post (as hopefully evidenced by the second quote) but more about how the concept of L2Arc works (which hasn't changed - and is pretty well explained by the thread quoted by me) It basically boils down to this: You Arc is your performance...

See if this is a quick-fix for your issue. (i typically force refresh the gui after it and get prompted for login credentials.

did you reset browser cache ?

Afaik (and its been a minute since i've done this) you can either pass through 03:00.0 & 03:00.1 (as in 03:00) or 09:00 or 0a:00. The reason for this is that the first 2 nics sit on the same iommu group, while the last 2 nics sit on seperate ones. Any chance these are a dual port nic and 2...

This is a good primer on L2Arc IMHO: https://forums.freenas.org/index.php?threads/at-what-point-does-l2arc-make-sense.17373/#post-92302 It is based on FreeBSDs version of ZFS, but explains the mechanism very well. regarding 70 bytes vs 380 bytes.

Yes. Your server is a single Socket Server (only one CPU) proxmox license is per physical CPU (also known as socket) so your looking at 6.29 US Dollar per month for your server. Thank god (or the equivalent of your denomination) they do not charge per core or vcore like some people have...

Ceph can definitively be the tool for this task. We do host a customer's cluster of 9 virtual Mail-Servers (Zimbra) on tiered Ceph-Storage hosted in 3 separate Data-centers. maybe 2k users (guesstimating) What this means is: We have multiple ceph-Clusters, that have servers in each of the...

This made me smile In these parts "." represents the same as "," used by americans :P Community licence starts at 5,83 EUR/month (per CPU) which is basically 6.29 USD/Month

have a look here: https://www.proxmox.com/en/proxmox-ve/pricing at today's rate 1 Euro equals 1.08 US Dollar ps.: the community subscription should be sufficient for you. pps.: you also get Access to Enterprise repository

glad i could help :rolleyes: I was a bit pressed for time when reading your post, but remembered I once set up something similar using that guide.

AFAIR you can do the following: make changes to nano /etc/network/interfaces then invoke them via /etc/init.d/networking restart The Problem in my opinion becomes, that once you make changes on the proxmox gui, all changes that have not been done via the gui/api get reverted. This sounds...
