IITT reacted to cwt's post in the thread Can NUMA node be a reason for ESXi vs Proxmox Performance differences? with
Like.
I wouldn’t conclude that there are “no such rules for Proxmox”. There are just different layers involved here. Linux itself is NUMA-aware: the scheduler and memory allocator try to maintain CPU/memory locality. QEMU can additionally expose a... -
Jj.theisen replied to the thread HPE MR416i-o & HPE MR408i-o Gen11/10.Hi @Patrik_V thank you for posting on the forum! This will probably never work since ZFS is not designed to work with hardware RAID controllers, see [1]. If the MRs are running in HBA mode it should be fine, but RAID mode is not supported...

LnxBil replied to the thread LVM Snapshot-as-Volume-Chain: Newly created qcow2 image reuses old guest data after VM deletion.Of course it's expect. Why would there be an option to wipe the volume if you would have the same without wiping it? -
OOnslow replied to the thread LVM Snapshot-as-Volume-Chain: Newly created qcow2 image reuses old guest data after VM deletion.Welcome to the Forum, @krisshurley I think this is the similar situation like mentioned e.g. there: https://forum.proxmox.com/threads/lvm-storage-on-san-new-vm-and-disk-show-data-from-a-previous-deleted-system-disk.179574/ The solution is...

LnxBil replied to the thread Synology SAN Manager storage plugin for Proxmox VE (iSCSI, snapshots, multipath).AFAIK or as other plugins do it, you don't have LVM and multipath part. The iSCSI volume can be directly attached to QEMU, so no middleware needed. For the FC-part, a lot needs to be changed in the backend for this to work. I tried it years ago...

Kkrisshurley replied to the thread LVM Snapshot-as-Volume-Chain: Newly created qcow2 image reuses old guest data after VM deletion.Yes, I have tested both configurations. With Wipe removed volumes enabled, I cannot reproduce the issue. With it disabled (the default configuration), I can reproduce it consistently. My expectation is that a newly created qcow2 image should...

Aabhijithiaaxin replied to the thread Proxmox + Ceph across 2 datacenters.@gurubert , @aaron Thanks for the information. Yes, our plan is to keep all 4 nodes as a single Proxmox cluster. Our main requirement is that our production VMs/web applications should continue running if one complete datacenter goes down...

AAs @gurubert already mentioned, you will need one node in a 3rd location. Our Stretch Cluster guide has more details on how to get it up and running: https://pve.proxmox.com/wiki/Stretch_Cluster You will have to span up a layer2 network between...

Aabhijithiaaxin reacted to gurubert's post in the thread Proxmox + Ceph across 2 datacenters with Like.
Basically you need three locations for automatic HA. Otherwise you will always have issues with split brain situations. Addendum: If there is no common layer 2 network available for the VM traffic you cannot migrate a VM from one location to the...

Run a VM that provides a network file share. All things can be accomplished in the same way as you would do with multiple physical systems (except that you use VMs or containers). EDIT: TurnkeyLinux provides VM/CTs that can run on Proxmox, see...
