Hi Martin! Definitely no problem in having cluster members that are different (aka not-identical). I am uncertain, how live migration copes when (if) you moved from <>To dissimilar CPU type (ie, AMD on box1 and Intel on box2?) but maybe someone else knows answer; or possibly you have not such...

Hi, just to confirm. You are using 4.x proxmox latest, have installed a VM (happens to be CentOS Guest) and you are having trouble with metrics being visible on summary page ? This is something that just 'works' at the proxmox level, it is not related to what guestOS is running inside the VM...

Hi, devlis advocate, question -- I wonder if ZFS is adding complexity here / and might it just work 'simpler and better' with vanilla HW Raid. Or you can do HW Raid of (rust disks) and HW raid of (SSD disks) and do a debian-install proxmox; configure bcache layer to get SSD boost over the...

Just to chime in to agree, this seems a 'storage performance' sort of issue as the fsyncs/s stat suggests from your CLI. things that would help - I like the suggestion of the intel SSD, probably is simplest - more 'splindles' will increase your performance here, ie, more parallel channels for...

Hi! For what it is worth. Not to be a negative - speaking / un-positive sad-faced person. But, maybe my lesson will be of slight use, or possibly elicit a counter-story from another posting person. I spent some time last year doing a test config build on 4.X.Latest - the work spanned a couple...

Hi Peter, I think your situation is a clear cut one fortunately. Maybe the confusion part of it arises from the detail, there is no concept of 'master' node in proxmox, but rather, all nodes in cluster, can be used as a node from which you manage the cluster (ie, via WebUI for manage tasks...

Are you 100% confident you have all syntax proper? For example a /29 subnet should be, 255.255.255.248, as your subnet mask I believe, yet in your text above you hide-out the last 3 digits, which really are not such secret and personal data anyhoo. (?) Maybe just for giggles, reboot your...

Hi JC, I am not entirely certain I understand how your nginx instance is desired to be communicating with the proxmox underlying bare-metal host. I briefly skimmed https://github.com/firehol/netdata and I'm guessing, maybe, you are trying to use something like IPC/Semaphore and this is timing...

Hi Steve, for sure this is outside of what I know - I only did a basic test install of Proxmox 2-disk ZFS raid ~>1 year ago; tested it a bit; was not happy with how things behaved (ie, had to tweak settings on some VM configs for things to work as expected? and found performance was not so good...

Hi, yes, it is true, snaps can be useful for very short on-demand install config work, if used properly. (ie, delicate installs of PITA apps). I've seen snapshots used poorly so many times as well that I am sometimes leery about their use in some cases. (ie, ever heard the story about the VM...

Thanks for pointing out this documentation. It is 'more recent' and I have not read that before. From reading the thread this morning / I gather there will be a bit more updates even to try to clarify what scenarios snapshot are supported. Broadly speaking, I think you will find that the...

Just looping back to the original question, I think maybe for clarity? I would say: Originally Questions: Any recommendations which one should be tried? Performance and resource differences? Which is more future-proof? Summary of answers to date: LVM-Thin is not same as LVM. Don't confuse...

Hi DG, thanks for the extra clarification on your environment. I agree that shared storage is not always possible, or desirable, depending on the situation. For what it is worth as an FYI, there are non-free NFS Filer "Appliances" (ie, lnux under the hood, and built on standard-based...

OK - all clear! For sure there is downtime involved with multiple reboots to de-christen the proxmox cluster and then change IPs and then re-create a 'new' cluster on the same nodes. Strictly speaking it can be done fairly quickly (slowest step is the speed of reboot on your server, which...

Hi, I think I misunderstood what you said in your original post. I took your words, "move cluster to another subnet" to mean, "we will be changing the IP address of the proxmox nodes". Broadly speaking my observation with proxmox cluster, -- it is fussy if you create a proxmox cluster, and...

Hi, glad to hear your dell 6220 units are in active pre-production. If the LSI controller you mention is 'fairly standard part' (which I am guessing it is - I think LSI HBAs are well supported on debian and thus proxmox) - then I would anticipate it should 'work fine'. I have ~various clients...

Hi, sorry for my vague reply :-) I guess what I meant, somewhat, to say but didn't say so clearly, - perturbation to the clients (cluster nodes) may trigger reassessment of the cluster status. - this may include, reboot of nodes, but also network hiatus, NIC unplug, spec of lint, atomic dust...

Hi Seppo, glad to help / and thanks for your clarification followup posting. I quite understand it is frustrating when things go sideways like this. End of the day I think the Proxmox dev team have limited time to do 'customizations for edge-use-case config' such as grub repair. In my...

Hi, In case this helps at all ? I deployed proxmox on some vaguely-similar supermicro units (2 nodes in one chassis) in a 'semi-production test lab' for a client, and it was all very 'straightforward'. My experience with proxmox installs generally - Most servers (esp. from big vendors) use...

Hi VM Guy, happy to read your thread and that this is working. Proxmox is an amazing tool for learning and test-lab. and also for production VM hosting! :-) It can be easily installed to various hardware - if you find you need to stretch out capacity a bit more from your old dual-core rigs; any...
