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...

Good afternoon all, I had an NVMe drive in my proxmox system that died. I decided to just take it out. Unfortunately the LVM drive is still showing on the main dropdown and I'm not sure how to get rid of that. It's not causing a problem, but just bugs me. Any help would be most appreciated.

Hi everyone, I've seen a couple of posts around regarding this after the 8.4 upgrade this week and thought it was worth making a separate post to draw better attention: Previously there was a hack-around out in the wild which was (at least) being used to boot up macOS install media; in this...

I installed proxmox on an nvme drive using the default (lvm) storage setup. I then created a vm running home assistant and have been happily using it. I would now like to change my system to be zfs based but I do not want to have to manually set up / replicate my home assistant vm. In order...

Hi Team, currently i am facing a question which is somehow hard to understand for me. Maybe you guys can push me to the next level of understanding ;-) Last days we configured 2x PVE and a QDevice where the PVEs facing a NetAPP SAN Storage via FC. The Storage is connected via two times fc...

Hi ! I'm a beginner with proxmox, and I don't understand why my vg pve is full ? I have only 4 VM and 2 snapshots. How can the 11TB be totally used in this case ? Did I miss something during the installation ? How can I fix this problem ? I apply this configuration during the graphical install...

How to access the lvm disk when VM is in powered off state? We do not see the disk in lvm, see output below: root@be-proxmox1:/dev/pve# pvesm path lvm1:vm-105-disk-0 /dev/lvm1/vm-105-disk-0 root@be-proxmox1:/dev/pve# root@be-proxmox1:/dev/pve# ls -la /dev/lvm1/vm-105-disk-0 ls: cannot access...

I have a fast 2TB NVME SSD and a slow 4TB SATA SSD inside a RAID0 zfs zpool. I like zfs (over lvm which I had before) for its versatility in managing storage (e.g. one pool to use, including the pve root), however I'm running into the issue that my mixed hardware slows down. With LVM, I could...

After finding this thread I was able to extend an LVM-Thin pool on multipath iSCSI on TrueNAS, but it took many steps (shown below) to do this. Did I miss something? Is there a better way to do this? Initial state after increasing the size in TrueNAS from 500GB to 2TB # vgdisplay...

Hi there, I have two Proxmox VE 8 servers called proxmox1 and proxmox3. The backups of proxmox1 are validated every night (copy to Debian desktop, decompress, start and ping). Proxmox3 is an old Dell Precision T1650 meant to serve as backup in case proxmox1 fails. It has a 512MB NvMe on a...

Hello folks, I am new to proxmox and I am trying to find a way in shell cli to move disk from mounted VMFS disk to LVM disk. I created a PV and VG on top of PV then a LVM storage using the VG. This is where I save all the VM disks in raw format. This LVM disk is a SAN disk shared between...

Hi. I have been using proxmox for a while now, but I still get confused when setting up my storage. Scenario A: I am currently setting up a homeserver for a friend who wants to experiment in a homelab. Available storage options: 500gb pcie nvme 1 TB SATA SSD 4 TB HDD This setup is for home...

during installation were defined the 2 datastores as LVM. It was only discovered afterwards that no snapshots are possible. What options are there for converting these datastores to LVM-thin and preserving the installation of the two VM machines? dir: local path /var/lib/vz content...

hi everyone, a very strange thing happened. I got a cluster on 2 HPE DL830 with a fiber channel disk bay MSA family, originally in PVE 6 I carefully read about https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0 I migrated all VM from node 1 to node 2 upgraded node 1 to pve 7, rebooted node1...

Hi all, I am looking for a fast storage for HA cluster. Currently I use Ceph, but it is terribly slow (I have 3 nodes with enterprise class nvme drives. I read many articles about it and its performace. By my opinion the bottleneck is in network synchronization. So I am looking for another...

Hi Everyone, There are numerous forum inquiries about integrating a legacy enterprise SAN with PVE, particularly from those transitioning from VMware. To help, we've put together a comprehensive guide that explains how LVM Shared Storage works with PVE, including its benefits, limitations, and...
