Aalexskysilk replied to the thread Retired Systems Engineer Installing Proxmox for Home Lab and Learning.Understand that PVE is not designed or meant to operate as a desktop OS. I see two rational options depending of the answer to a simple question- are you intending to use this computer as a workstation or will you be attaching to it over the...

Aalexskysilk replied to the thread Initiate VM migration if host loses network connectivity to VM network.this is a chicken and egg problem. IF your host loses cluster connection it will be fenced and the vm will be restarted on a surviving host. IF you are concerned with any of the other networks, you will need to write a monitoring routine and...

Aalexskysilk replied to the thread Proxmox with 48 nodes.The number of cluster members is an inexact limit. that ACTUAL limit has to do with how much data the cluster members have to keep synchronized- if each of your cluster members had 400vms with continuous api traffic- your cluster would probably...

Aalexskysilk replied to the thread QCOW2 on ZFS, but over NFS?.ahhh but thats only the beginning of the pain. you also need to coordinate guest quiescence (freeze/thaw) with appropriate state detection, write the snapshot state data into vmid,conf, snapshot chain management, restoration logic, control...
-
Aalexskysilk replied to the thread PVE 8.4.12 Data Hunt for Recovery.yes. you've already been given answers, you just dont like them. reinstall and restore from backup. fixing your install is more complicated and will require you to read documentation instead of just posting questions that are covered there.

Aalexskysilk replied to the thread PVE with antivirus.If you're asking to add AV into the scope of PVE, say so. if you're not, what possible reason would the devs have to even have a position? like you pointed out, its just Debian- if you can run it on debian you can run it on PVE. Anything...

Aalexskysilk replied to the thread QCOW2 on ZFS, but over NFS?.fs-freeze/thaw are supported and utilized on zfs snapshots. its perfectly safe and works well.
-
Aalexskysilk replied to the thread PVE with antivirus.Saying what? I have no idea what that means, an anti virus is only applicable to its host operating system especially if monitoring RAM. a windows av is of no purpose if you're running PVE and vice versa- there is no such thing as "antivirus...

Aalexskysilk replied to the thread Ceph Cluster - Slow performance.define slow. and post your /etc/network/interfaces and /etc/pve/ceph.conf
-
Aalexskysilk replied to the thread How many nodes in a single cluster with Ceph requirement?.That was assumed. I meant, how much power are you BUYING? Thats well and good but doesnt really address the load question, which means we still dont know how many nodes you'd need. You should also be aware that at 2.2GHz its single thread...

Aalexskysilk replied to the thread Proxmox and IBM Flashsystem 7300.dont trust AI slop ;) only Truenas has a plugin available for zfs over iscsi afaik, and its not provided or supported by either Proxmox or Truenas. The rest dont expose the underlying filesystem (and is not zfs at all.)

Aalexskysilk reacted to bbgeek17's post in the thread [TUTORIAL] Understanding QCOW2 Risks with QEMU cache=none in Proxmox with
Like.
Hey everyone, A few recent developments prompted us to examine QCOW2’s behavior and reliability characteristics more closely: 1. Community feedback There are various community discussions questioning the reliability of QCOW2. We have customers... -
Aalexskysilk replied to the thread Using qcow2 for 20TB disks on iSCSI SAN (NVMe, 25G, multipath) — any risk of corruption or performance issues?.big data vms is unecessarily vague. native storage= NAS.
-
Aalexskysilk replied to the thread How many nodes in a single cluster with Ceph requirement?.its an innocent enough question- but there are a lot of gotchas you need to consider. Clusters are made up of 3 elements- compute, storage, and networking. lets touch on each. COMPUTE: - Dell R630 is a 10 year old platform. as such, it offers...

Aalexskysilk replied to the thread Using qcow2 for 20TB disks on iSCSI SAN (NVMe, 25G, multipath) — any risk of corruption or performance issues?.It would be worthwhile to consider this question in light of the use case. Normally when you have large datasets its better to leave the data on native storage; why are they such large virtual disks?
-
Aalexskysilk replied to the thread Proxmox HA cluster with Ceph.Where did you get that idea?! ceph doesnt care about ANY of those things. Just be aware that the overall performance of the cluster will be as slow as the slowest monitor. ceph doesnt need or perform any live migration. As for memory, nodes...
-
Aalexskysilk replied to the thread Considering Proxmox use case...doubts..This CAN be done, but only if you use MACOS as your parent OS and virtualize windows and linux- you can use parallels, vmware (which is free now btw) or UTM. PVE is not meant for desktop use as you describe.
-
Aalexskysilk replied to the thread About Proxmox VE & PBS features.the OG percs did. ever since 13g all percs including the H7xx and H8xx series offer naked passthrough mode- so anything 12gig SAS or newer.
-
Aalexskysilk replied to the thread Comparison of virtualization feature set: XCP-NG vs PVE (Proxmox) -- VMware migration decision (VMware Alternative).The whole discussion around storage options seems to be needlessly around filestore. first class storage citizens for PVE is ZFS (standalone) and Ceph (Cluster.) reusing existing iSCSI/FC SANs necessitates tradeoffs- PVE means no snapshots (this...

Aalexskysilk replied to the thread Proxmox VE host backup - best option for now.This isnt necessary if the original datastore still exists. Once you restore storage.cfg everything should just work.
