lvm

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...

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...
