Aalexskysilk replied to the thread How to move a VM from one cluster to another.Having the datastore mounted on two separate clusters can be really dangerous, since the clusters dont share file locking information. That said, if you are able to make sure they dont try to consume the same resources at the same time, what you...

Aalexskysilk replied to the thread A question about storage design.Why is everyone using passive voice when recounting that "consumer drives are discouraged?" by whom? and under what circumstances? There is nothing INHERENTLY wrong with using non enterprise drives for zfs pools, as long as you understand the...

AWe did a deep dive on this feature in this article: https://kb.blockbridge.com/technote/proxmox-qcow-snapshots-on-lvm/ https://forum.proxmox.com/threads/inside-proxmox-ve-9-san-snapshot-support.169675 Blockbridge : Ultra low latency all-NVME...

Aalexskysilk replied to the thread A question about storage design.a couple of thing: 1. if you do wish to deploy lvm on mdadm, you can. it just requires a bit of "linux" setup. but you shouldnt, because 2. a zfs/btrfs mirror is seamless, has filesystem integration, inline compression, snapshots, etc. it is a...

Aalexskysilk replied to the thread [SOLVED] WinXP conversion from esx to pve refuses to boot.If memory serves, Windows XP allows a repair install. just boot the windows xp iso (sata/ide host bus for the existing virtual disk) and reinstall. Its also possible to use universal recovery from Acronis to reset an install using new hardware.

Aalexskysilk replied to the thread Recommended amount of swap?.since you're in a cluster, the conversation should expand to include provisioning in general. measure your total provisioned RAM across your entire cluster. assuming your cluster nodes are identical and have no additional host load (eg...
-
Aalexskysilk replied to the thread RAID expand - LVM-thin expand & resize.if its not obvious- have a backup before doing anything to avoid crying if/when you're not executing properly ;)
-
Aalexskysilk replied to the thread containers too slow.check dmesg on the host for OOM messages.
-
Aalexskysilk replied to the thread Bind9 Installation fails using Proxmox 9.0.there may be an issue with bind and trixie, BUT you really dont want to run bind on your hypervisor anyway. put in on a vm or container.
-
Aalexskysilk replied to the thread vm offline migration from cluster to cluster using Netapp Storage.this is due to the stats collector being in a hung state. make sure there are no vm's still referencing the missing datastore; if the question marks are still there: 1. check pvesm status. there should be no unknown datastores 2. systemctl...
-
Aalexskysilk replied to the thread Recommended amount of swap?.the PVE install defaults are designed for "homelab." you can and should ignore them if you're using for production. you can change this at any time. and should. No. You have 256GB of ram. swap can only slow down your VMs if its ever actually...
-
Aalexskysilk replied to the thread CEPH Erasure Coded Configuration: Review/Confirmation.The placement logic is per node, not per drive. the only sane EC config possible with 3 nodes is 2+1. But bear in mind that while you CAN do this, its not really supportable; on node down you're operating without checksum at all, and under normal...
-
Aalexskysilk replied to the thread Please help with Proxmox VE 9 Cluster and Alletra B10000 Via iSCSI.AFAIK Multipathing is the preferred method to address iscsi over bonded interfaces as it is completely agnostic to the network configuration and features- but bonding can work as well. if you DO want to use bonding make sure both ends (host and...
-
Aalexskysilk replied to the thread PVE Replication with ext4.I think this is the part of the conversation where we investigate the WHY. If your intention is to live migrate without shared storage, any CoW backed storage (zfs, qcow, even lvm with snapshot) would work and doesnt require any additional steps...

Aalexskysilk replied to the thread [Proxmox Cluster with Ceph Full-Mesh Network Design] Sanity Check & Advice for 3-node cluster with separate 10GbE/25GbE networks.you understand that you cant EXCEED the speed of your public interface to a single host...
-
Aalexskysilk replied to the thread Deleted.in that case, the only difference is in load calculation. Since Zen4 and Rocket Lake have similar IPC performance, its a simple matter of: Relative Performance, Xeon E-2388G (3.2GHz base, 8 core)= 25.6 Relative Performance, AMD EPYC 4244P...

Aalexskysilk replied to the thread [Proxmox Cluster with Ceph Full-Mesh Network Design] Sanity Check & Advice for 3-node cluster with separate 10GbE/25GbE networks.It actually cant. keep in mind that ceph uses networking for both host and drive traffic, which means you need to double the bandwidth vs filesystem throughput.
-
Aalexskysilk replied to the thread Deleted."perform better" doesnt mean anything. do your application require specific feature? do they benefit from scaling up or sideways (do your apps need clock speed?) Next, what are your IO needs? the Xeon part has 40 lanes of gen4 PCIe; the Epyc...
-
Aalexskysilk replied to the thread PVE Replication with ext4.Your root file system doesnt really matter for the purposes of this discussion. only the vm storage does. Assuming you intend to use the same filesystem for your OS and payload, you cant use ZFS replication- but that doesnt mean you cant...
-
Aalexskysilk replied to the thread [Proxmox Cluster with Ceph Full-Mesh Network Design] Sanity Check & Advice for 3-node cluster with separate 10GbE/25GbE networks.I've only ever used mesh in a lab scenario, and that was some time ago. I used broadcast bonds and it worked well enough. Im fairly certain that no logical topology will result in any meaningful difference in performance, but as for stability...
