shared storage

It's not clear from the documentation, but looks like the shared flag only makes sense if the storage is for vm disks, so PVE would know not to copy the data if a vm is running on a shared storage. The question is whether it is needed to tick "shared" if it's a shared storage for backups? Does...

Hi there, I currently have a Proxmox Cluster with 2 identical Hosts with SAS cards and a V3700 V2 Storage that has each storage-canister directly attached to both Hosts with SAS cables. I was able to successfully configure multipathing and create an LVM on it, however, as the documentation...

Hi people! As it's a common thing right now, giving the broadcom decitions, my company it's looking to migrate to a more viable solution in economic terms. I've been trying to set up a HP Fiber Channel Storage with multipath, and i'm really struggling here... (We use this type of storage in...

Dears, I'm preparing to setup 3 node Proxmox Cluster using Dell R740 for our production systems. I am trying to decide between using CEPH storage for the Cluster / Shared storage using iSCSI. Which is the best option for Shared Storage in case of 3 node Proxmox cluster? I need a reliable...

Hello, I am planning to migrate from oVirt to new Proxmox cluster and I i need hardware recommendations for storage. Right now I have 2 Supermicro SYS-121C-TN2R servers with 2x 4410Y CPUs and 256GB of RAM with 10Gbps NIC interfaces connected to Synology NAS via iscsi. Since this Synology is...

Hello Proxmox Community! We have lots of costumers running esxi with a shared storage and fibrechannel san, who are willing to replace their hypervisor. And 99% of these customers have VEEAM in place as a backup solution. As VEEAM announced support for Proxmox, our customers are really...

Currently, I have 1 disk in each server(total 3) used for Ceph shared storage. I noticed that if 2 out of 3 disks are not working then complete ceph will also stop working. I am not sure if the same (n/2 +1) formula works here as well. Why It is concerning is because we are using CephFS as...

Hi, I know that there is already "LVM over iSCSI/FC" for shared block storage (SAN) which carves out LV from a shared VG/LUN for individual VM disks - but with no snapshot and thin provisioning support my question is why is there no (extended) storage plugin which provides 1.) "QCOW2 over/on...

Server - 2x CPU / 768 GB RAM / 6x 1gbe NICs / 2x 10Gbe NIC's Storage - Very High end flash storage Networking - 2x Switches for "server access" (iLO / iDrac + back end server network) -- we will call this management - 2x Switches for "Trunk Network" (VM's live here) -- we will call this VM...

Hallo zusammen, gibt es aktuell Pläne einer Verwirklichung von SAN (iSCSI / SCSI) Support mit Snapshot Funktion bzw. den offiziellen Support eines shared Filesystems um qcow2 verwenden zu können? Falls nicht, gibt es eine Empfehlung welches shared Filesystem hier evtl. gut und sicher in einer...

Example- **************** Cluster- node 1-> has VM-1(on local storage) node 2-> has VM-2(on local storage) I am already using Ceph and HA. I want to use VM-1 and VM-2 "tmp" directory to be synced. I was thinking of mounting some storage from the Ceph storage pool in VM-1 and VM-2 for...

Hello. So I've gone through what I think are the docs regarding PROXMOX and fibre channel presented LUN's. I'm using an older 3PAR 7200 in my lab, attempting to get shared storage between a PROXMOX cluster. So far, I have a fully operational cluster with a shared NFS volume, which performs...

Indeed, Proxmox will not work when 2 out of 3 disks die in shared storage. My question is what happens when 2 disks in servers are RAID 1(shared storage) and one of the disks from two servers die? Will the Proxmox server use the raided disks or will it die?

We had an issue and removed one out of 3 disks used for HA. The system is working fine, but when we tried to add the disk back. Ceph shows drive 'in' but it is not adding it to the pool automatically for read/write. I pressed 'start' and checked the log which shows '33.333%' degraded. Used CLI...

I am already using HA, Ceph, 10G network, and shared storage. I noticed my VMs are restarting.

Hello dear Proxmox forum members, I am planning to create two Proxmox servers, server1 (low spec) and server2 (high spec), both OS on ssd drives. On server2, I will install two 1TB NVME drives. These drives I want to unite them and make them available as a shared storage between the two...

We have PVE running, with VMs and Containers running over NFS share to our Synology. We mostly leveraged VMs, so at the time I hadn't realized that Snapshots on NFS for containers would be an issue. Now I am starting to use LXC more often and would like to be able to have snapshots. The options...

Hi, This is an idea that makes a lot of sense to me, yet I'm not able to find people talking about it so it's probably a bad idea. Still I would love to know why it's bad. Before anyone asks, no I'm not planing on using this in production. According to the docs PVE supports shared LVM storage...

Hello, I'm setting up a new proxmox server for myself (homelab). I am in the process of adding a synology share that I had setup on my old lab and i'm wondering which option(s) would I need or recommended to just give read access to my proxmox server in the Content drop down? Thank you.
