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...

Hi! I have run dual-primary drbd successfully with two node proxmox cluster, each pve node being also drbd node (and using local storage). And /dev/drbd0 block device is used as lvm pv device, lvm needs to be initialized at one node since block device content appears or rahter is same and both...

root@pve:~# pvesm status activating LV 'storage01-slow/storage01-slow' failed: Activation of logical volume storage01-slow/storage01-slow is prohibited while logical volume storage01-slow/storage01-slow_tmeta is active. Name Type Status Total Used...

I have some filesystem questions regarding PVE, ZFS and how they interact with VMs. The storage system I'm trying to achieve consists of 5 physical disks: Physical Disk Purpose RAID Disk 1 + Disk 2 PVE + mirror ZFS mirror Disk 3 + Disk 4 VMs and container storage a mix of striping and...

I have inherited a LSI SAS9200-8e 6Gb/s SAS PCIe x8 HBA in a Dell R710 server connected to a EMC KTN-STL3 JBOD with 15 1TB drives. I don't see the drives in Proxmox or in the Debian console. Can someone point me to a guide that explains setting up the server BIOS, the HBA's BIOS and/or...

I have built a 6.10 kernel using clang (with .config from generic ubuntu) on Ubuntu 24.04. I am able to run it on Ubuntu but not on Proxmox. On Proxmox, I get following error: Alert! /dev/mapper/pve-root does not exist. Dropping to shell Running lvm pvscan returns nothin, and adding...

I have been following some posts, but those were meant for ZFS. I already changed the configuration file of the VM and set the variable template: 0 Renamed the LVM from base-101-disk-0 to vm-101-disk-0 Now I'm trying to change the attributes from Vri-a-tz-k to Vwi-aotz-- assuming those are the...

I have a 128 GB internal SSD disk on my machine, and have installed a fresh Proxmox with the following setup: 16 GiB for the Proxmox OS root (set using the maxroot parameter during installation) 7.58 GiB allocated to SWAP 32 GiB allocated to VM-100 It seems that the proxmox installer has...

Hello! I reset my proxmox nodes hostname and then joined a cluster and now the dropdown for my node only shows local when it had previously shown several other disks/volumes. In disks/directory I see the directories of the drives and where their path is mounted and I can access all the data on...

Hi everyone, Proxmox newbie here. I got a few questions regarding vm disk management. Context: The main usage for my PVE, in a home environment, is mainly to host a file server and a multimedia server (DNLA-like), plus a few other small VMs for testing and playing around. The PVE has the...

Hello, I am fairly new to Proxmox. I've searched Reddit and this forum, and I hope I am not asking an FAQ that's already been answered. I couldn't find anything on the Web. Please bear with me. I have set up Proxmox on a NAS. Due to it only having 8Gb of memory, I chose to go with LVM+ext4 and...

Hi! I found some comments about using Snapshots (LVM or ZFS or GlusterFS ) in Storage causes disk performance degradation ( permanent slow I/O ), but if you remove all the Snapshots, the performance is returning to normal. Has anyone here had a similar experience?

First of all this thread is basically the aftermath of this one. It's not necessary to read it, but it paints a good picture of how this thing behaves. So I have 2 GPUs that I am passing through to 2 VMs (usually one windows and one linux or mac). Everything works fine when I am starting them...
