Had a client request a fully redundant dual-node setup, and most of my experience has been either with single node (ZFS FTW) or lots of nodes (CEPH FTW). Neither of those things seem to work well in a dual node fully redundant setup.
Here's my thinking, wanted to see what the wisdom of the...
I am trying to create a shared storage (nfs) to a Truenas machine in a 2 machine VE 8.x cluster.
I have direct 25Gb connections between the VE hosts and the Truenas host
I have updated the hosts file on the proxmox hosts and confirmed I can ping CIRRUS (truenas) from both hosts...
Hello community! There are two servers with one shared storage system via FC. I set up a shared LVM and a multipatch. I have doubts that everything is configured as needed. Proxmox version 7.4-3
I moved a number of vm with disks to these nodes, they were positioned very strangely. Some went...
I'm in the process of planning out a 3-node cluster for failover and high availability and have a question about where to store the VMs. Assume the following;
All servers are on a 10GB backbone
All servers have SSDs for OS and data drives
All 3 PVE nodes are identical. Same...
I currently have 4 identical dedicated servers, each with:
192GB of RAM
6x 1.2TB SSD
2x 10Gbps SFP+
My question is:
What is the recommended setup so that the data is replicated at least once (similar to RAID1 or RAID10, ceph shared storage with 3 nodes) and at the same time...
Hello Everyone. We received excellent feedback from the previous storage performance investigations, particularly the technotes on optimal disk configuration settings (i.e., aio native, io_uring, and iothreads) and the deep dive into optimizing guest storage latency.
Several community members...
I'm actually trying to live migrate one VM from host x to host y. The VM is located on shared glusterfs storage which is mounted on each of the hosts.
Following the error while trying to migrate the VM:
2023-04-13 22:58:33 use dedicated network address for sending migration traffic...
I am having Proxmox cluster with GlusterFS storage on which my VMs are running. I increased the disk size of the VMs but I restored them from backups which were having the previous disk size and I think that GlusterFS has somehow stored the states of those VMs and now my hard drive is full! What...
hello, it's me again. i defeated fc adapters and connected 2 servers to one storage with one shared drive, thanks everyone. now via shared lvm.
I connected them with another server in a cluster, so I have 2 servers with shared storage fc lvm + 1 server with local storage.
I wanted to clone my...
Removal of VM results in loss of hard disk on separate Node, FYI
Just starting using Proxmox and noticed the following WHEN USING SHARED STORAGE:
Create vm-id=400 on host-A with virt hard, this creates hard disk file <..smb..>/../images/400/vm-400-disk-0.raw
Create vm-id=400 on host-B with...
Several customers have asked us how to get the best possible storage latency out of Proxmox and QEMU (without sacrificing consistency or durability). Typically, the goal is to maximize database performance and improve benchmark results when moving from VMware to Proxmox. In these cases...
Hey how’s it going all,
I’m doing a bit of experimenting and wondering if it’s possible to have several Proxmox nodes each with their own local storage, and the VMs on that storage mirrored/synced onto a shared store; then HA setup so if any Proxmox node goes down, the VM is read/run/hosted...
We have a R7525 Dell server (2 sockets, 64 cores/socket, 2 Ghz base clk, 3.2 Ghz boost clk, 128 GB RAM, 96TB [8TB x 12] 7200 rpm SAS HDD, Dell BOSS S1 SSD 240G RAID1 boot, H745 PERC RAID controller with PCIe 4.0 bus. 2 x 2 raiser slots are available, one is having H745 RAID...
I have several physical servers which all are configured in same proxmox cluster. I'm facing problem in adding storage which needs to be shared between all nodes.
I have Fiber-channel based SAN storage system, and from that, normally a LUN needs to be created which can be exported to many host...
I was able to mount an external USB drive (NTFS formatted) on proxmox host using:
mount -t ntfs-3g /dev/sdb1 /mnt/pve/USBDrive (after installing ntfs-3g, looking up drive name, and creating mount point)
I could then go into Data Centre -> Storage -> Add -> Directory and point to...
I have been thinking of setting up Shared Storage for 3 Proxmox nodes. This will mean 4 systems (NAS, pve1, pve2, pve3). The NAS (for lack of a better name) will share to the 3 nodes using NFS or SMB and will hold all the VMs and CTs only; it will not be used as a multimedia server...
I’ve 3 servers each with 2 x 1TB SSD and 1 x 4TB HDD.
I want to build a Proxmox VE cluster with HA utilising the storage on each node.
What is the best way to create a shared storage from the 3 nodes and present it Proxmox?
I have succesfully configured a Proxmox cluster with only 2 nodes at the moment (planning to add 2 more nodes) and I'm experimenting different storage configurations.
I'm using an old setup no longer supported from Dell:
- 2 x Dell R720
- 1 x Dell MD3800 - SAN
The SAN is connected with...
Our current Proxmox cluster is connected to a single TrueNas Core Server. Most of the VMs are stored on a NFS-share, as this seemed to be an easy and usable solution at the time of installation. And actually it works quite well, but Snapshots via qcow2 aren't always nice to work with and there...
