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...

On a Hardware RAID configured system, we are having a hard time creating LVM2 groups on the RAID controlled drives. Whenever the hardware undergoes a physical power cycle, any LVM2 groups created on these drives are lost and cannot be recovered. Commands like `pvscan`, `lvscan`, or `lgscan`...

Hi to all just want to write it down, because it took my lots of time.I am trying to create a cluster with iscsi disks and lvm to test the cluster capabilities. My environment is cascaded,i mean .I have a Hp server with 3tb of disk and lots of memory. I installed Proxmox as Operating system...

Hi everyone, Merry Xmas! I hope someone can help with the following basic problem: I have just created my first cluster by adding a single new node. I would now like to set up the internal SSD in order to transfer some VMs over to it. However, it's not working like the master node. fdisk -l...

Hi community. I've just installed latest proxmox ve on a small server with 4 SSDs connected to the backplane. I chose ZFS RAID10 in the installation to have everything on these 4 SSDs. I updated, restarted etc and when I just wanted to deal with vms I realised that local-lvm has status unknown...

I've followed this blog post https://blog.evoluso.com/proxmox-remove-lvm-local-data/. Basically, i wanted to wipe the local-lvm, however, i end up with resizing root partition. I've run the following code: 1. Remove /dev/pve/data lvremove /dev/pve/data 2. Resize root partition lvresize -l...

Hello ! I am running tests using VDO pools and LVM thin pools. I've added this to lvm.conf : then ran : systemctl restart lvm2-monitor Following this RHEL documentation ...

Hello I wanted to test a procedure to rename both the Volume Group, on which I created an LVM storage, and the storage itself. Specifically on an ISCSI LUN I created an LVM storage named "vg-iscsi" , then I created a VM (VM-move (200)) vgs VG #PV #LV #SN Attr VSize VFree pve...

Hello, I have problems with various VMS that seems do not release unused space. Here is the VM Config: Here is the fstab: Here is the LVM config: Here is the Filesystem free disk space: I've also issued fstrim manually after poweroff/poweron the VM: But when I investigate du on...

Hi! I would like to ask about one phenomena which does not excatly break anything but is at times unconvinient. I have encountered it several times so i dont think it is specific to my particular case. block device is connected over iscsi to multiple pve cluster nodes and on this block device...

I'm learning by doing, so apologies if I've missed some basic steps or information. I have a three node cluster made up of Lenovo ThinkCentres (M900 TFF) that I got from a friend after his work decommissioned them. They've been working great, but only came with 128GB SSD SATA drives, which...

Hi People, Im having a bit of a weird issue where I have created a striped Logical Volume using the CLI but when I add it to the storage.cfg or use pvesm add lvm <STORAGE_ID> --vgname <VGNAME> to add it to the cluster it shows up as full. Im sure I am doing somthing really silly but I can't...

Im getting Can't open blockdev in my dmesg and journalctl in the proxmox HOST. its tmeta and tdata dms that shows this. Both for my truenasISCSI lvm-thin and the local-lvm thin. why is this happening, how do i fix? I have normal access to both storages, everything works normally at higher...
