    IsThisThingOn reacted to Johannes S's post in the thread Storage for small clusters, any good solutions? with Like Like.
    The point is that it's also often possible to do HA on the application level and might be even more relieable. For example for webhosting having multiple webserver vms (on different nodes) and before them a loadbalancer/reverse proxy like nginx...

    Let's assume that you have an application that runs on a Linux VM. That application is mission critical to you and your business. Now you could setup the hypervisor and network and storage and so on to be HA, which in return makes your VM HA. If...

    That is the money quote. But IMHO even more important, in many, many cases, making the server HA was the wrong approach to begin with. Making the application itself HA would be way cheaper, offer way better performance, less complex, and...

    IsThisThingOn replied to the thread SSD ZFS Pool keeps increasing in usage space.
    No worries. IMHO the IT world is complicated enough. So I like to keep stuff K.I.S.S. In your situation I would either A: change RAIDZ to a 3 way mirror, get another TrueNAS system with HDDs as ZFS storage system and put files on NFS/SMB...

    IsThisThingOn replied to the thread SSD ZFS Pool keeps increasing in usage space.
    Let me try a different way. Imagine how you write stuff. You have 16k volblockstorage. So proxmox offers 16k blocks to the VM. Now your VM fills one such block. We assume that the data is totally incompressible, wo we really have to write 16k...

    My company has been using Proxmox for a while now and have deployed in a variety of uses and I can confirm that Blockbridge has definitely been the most straight forward way to address the problems you've mentioned. While Proxmox doesn't official...

    Take this with a huge grain of salt. I don't know you or your customers :) IMHO you probably don't need HA. Redudant PSU and local storage is more than enough. And your next part is a good explanation why. That is not automatically real HA...

    I gave you one possible answer, but you choose to ignore it. As a funny coincidence you answered one of my questions by posting this picture; your volblocksize is 16k. So my theory was right. So again, every 1TB VM disk will not only use 1TB...

    IsThisThingOn reacted to Johannes S's post in the thread Offline USB Backup mit PBS – Removable Datastore zu langsam, welche Alternativen nutzt ihr? with Like Like.
    Was man versuchen könnte: Die HDDs aus dem USB-Gehäuse aus- und in den PBS einbauen, damit das initiale Backup nicht über den USB-Flaschenhals geht, danach ausbauen und wieder ins USB-Gehäuse packen. Generell werden aber HDDs und PBS zusammen...

    IsThisThingOn replied to the thread Offline USB Backup mit PBS – Removable Datastore zu langsam, welche Alternativen nutzt ihr?.
    Das ist ein ziemlicher edge case, der sich mit PBS nicht umsetzten lässt. PBS kann keine traditionell inkrementellen Backups. Wenn du es also 1:1 wie bei Veeam umsetzten möchtest, wirst vermutlich scheitern. Wenn du offen bist das System zu...

    You would have to provide a lot more information than what you posted here. Otherwise we have to make educated guesses ;) So just cluster, no HA? So you use ZFS and VMs use local RAW drives on ZFS? There are a few problems with that. Short: A...

    IsThisThingOn reacted to mram's post in the thread VM connection issues after subnet change. What am I missing? Real time problem. with Like Like.
    Do any of your VMs still have 192.168.8.x addresses statically assigned in them? Did you check your Proxmox firewalls? Try disabling the Proxmox firewalls. Do you have the KVM guest tools installed in the VMs? I assume they are Windows since you...

    Hi IsThisThingOn, thanks for your impressions. I tried to answer them in the best way, even if the topic is a very long one. In Windows environments you can do both at the same time, permission management via User/Groupmembership for the...

    IsThisThingOn replied to the thread PVE to PBS.
    It depends. Windows uses the User / share permission and uses a more restrictive AND permission logic. But for Users and groups, it uses the less restrictive OR permission logic. And Synology does this stuff again differently by using the more...

    of course, why should it not? no need to censor rfc1918 :) Looks like a permission error. Take a look at this: https://pbs.proxmox.com/docs/ Now what tripped me up the first time setting it up, was this paragraph here: Permissions for API...

    a backup isnt a backup if it depends on the primary for function.

    You don't have to, but I would highly recommend it. Also make sure it is offsite in case of a fire.

    IsThisThingOn replied to the thread Performance Probleme.
    Sorry, natürlich lz4. Denke ich auch. Das führt dann zu einem "richtigen" 1M record + 1M record der nur zu 10% aus Daten und zu 90% aus Nullen besteht. Daraus resultiert ein 2M write ohne Kompression. Mit lz4 wäre es selbst bei nicht...
