TrueNAS created a ZVol, Sparse: on; created a iSCSI target, Disable Physical Block Size Reporting: off. PVE mapped iSCSI target, "format" and use it on VM, works no problem. on VM creation, one than one vm-<ID>-disk-<ID> will be created. For example 1G disk created. The issue is after...

Hi I'm trying to configure shared iSCSI storage for my 3-node Proxmox cluster. I need all three hosts to access the same iSCSI storage simultaneously for VM redundancy and high availability. I've tested several storage configurations: ZFS LVM LVM-Thin ZFS share Current Issue With the ZFS share...

Hey, if I try to create a LXC Container on my Proxmox, it takes up to 5 minutes. The issue doesn't appear when I install a VM. While a container is creating, the disk usage for that disk is at 100% (checked with iostat -x 1) I also tried to write with "dd": root@pve1:~# dd if=/dev/zero...

Hey, on a shared storage with hundreds of VMs, I have one VM that seem to constantly switch to the "io-error" state. My setup: I have a non-thin LVM, that is connected via FibreChannel to the host. The physical volume is 8TB big. Only ~3TB is assigned to VMs, so I don't think it's an issue of...

Hello All, For powered-off VMs, we cannot view or query the size of QCOW2 disks on LVM storage — unless the VMs are powered on or activated via SSH. Is this a bug?

Hi. I've updated some of PVEs to version 9 to test the new snapshot support for LVM thick storage. I've created the LVM storage which is shared among nodes in cluster, checked "Allow Snapshots as Volume-Chain" during storage creation, moved some VMs there and when I go to VM -> Snaphosts it...

Hi. I've recently added an LVM thick storage to my PVE cluster which is a LUN shared between 4 of 5 nodes and everything works just fine except VM migration. I migrated VM from the 5th node which only has local storage to different node and shared LVM storage. Now I can't migrate it back. When...

Hello! I'm preparing to upgrade a cluster to pve version 9. The readiness script has flagged LVM autoactivation as a potential issue. Will running the script to disable LVM autoactivation interrupt running VMs across the cluster? I have a few nodes still on pve 7, but I will be updating them to...

Hi Everyone, I'm excited to share a deep dive into one of the notable new feature in PVE9: the enhanced snapshot functionality designed for legacy SANs. This feature represents a meaningful step forward in expanding PVE's compatibility with traditional enterprise storage setups, something many...

Hello, I found out that after proxmox starts VMs which have their disks on iscsi storage and are expected to autostart fail to do this because their storage is not ready yet. By the time I login to the web gui I can start the VMs by hand with no problem: ........... Aug 12 07:00:11 hv02...

Hello freaks, maybe I’m just being dumb right now, but I can’t seem to install a Proxmox server without it automatically setting up LVM on the system/root disk. I’d really prefer to work with classic partitions because I’m not a big fan of LVM. Maybe I’m missing something—please give me a hint...

Hello guys! Can i migrate on proxmox installation in LVM to ZFS without formatting the system? Thanks!

Hi everyone, We currently have the following setup running under VMware, and I’m looking into migrating it to Proxmox VE: One physical server: HPE ProLiant Gen11 One external storage system: HPE MSA 2060 FC, configured with a RAID MSA-DP+ array built from 24 HDDs The server is connected to the...

Hi All, I see others have noted this issue, but it was never clarified if PV/VG/LVM creation on each node should be handled automatically when creating a shared LVM over iSCSI storage at the cluster level. The primary node creates everything and storage.cfg syncs across however the other 2...

Hi all, I need some advice for a new upcoming project. I need to setup a 3 node cluster using NetApp as storage. The cluster will start running only 8 VMs, details below: - 6x - 64GB RAM, 32vCPU, 50/100GB OS Disk, 4TB Data Disk (i know it's a nightmare) - 2x - 32GB RAM, 16vCPU, 30 OS Disk, 1TB...

TL;DR: Getting error trying to move Local-LVM to iSCSI. Getting error create full clone of drive scsi0 (local-lvm:vm-102-disk-1) TASK ERROR: storage migration failed: can't allocate space in iscsi storage Short Story Long: New to Proxmox, but have been expanding my knowledge of it thanks to...

Hi, I’m experiencing very slow disk migration in my Proxmox cluster when moving a VM disk from FlashME5 (iSCSI multipath + LVM) to CephStorage (RBD). Migration from Ceph → FlashME5 is fast (~500–700 MB/s), but in reverse (FlashME5 → Ceph) I only get ~200 MB/s or less. Environment: Proxmox 8.x...

Good Day, After searching the forums and web in general, I think I know my answer, but would like to defer to the greater knowledge of the forum. Apologies for the long post, but without all of the information, my question may not make sense. I have convinced my workplace to give up its death...

Hi guys, I have a rather strange problem with my current proxmox configuration. The status of 2 out of 3 nodes always goes to unknown, about 3 minutes after restarting a node. In these 3 minutes the status is online. The node I restarted is working fine. Does anyone know what I have done wrong...
