lvm

Recently we have purchased a HP MSA 2060 FC which we are using it as main storage for VMs. However, we have another san fc storage which is dell powervault MD3800f. we would like to know the best practice way to setup the dell storage as backup for the VMs. I just confused how to add a block...

Hello, I'm in the process of setting up a HP MSA2040 SAN to work with Proxmox. As I just started using a SAN, I have a little over zero knowledge of these things, so there most probably will be errors in my setup (or terms I don't use correctly). Current status is: - MSA2040 is connected via...

When using lvm as virtual disk storage it is not enough to pass additional parameters for lvm Example use in console: lvcreate -n vmid-disk-0 --type striped -L 32G -i 4 vg In VG can have e.g. 4 disks (or another number), and the final LV can be created with different parameters, for different...

Hi, im getting this error when i try to move a MV disk from one path to another. I think this have no sense because i think i have enough free space in my lvm, aprox 380GB in the local volume and 1.5Tb in the local-lvm. Im trying to execute this command. mv...

Hello, I've found a few threads about similiar problem but none of them have a solution. We have a 3 node cluster with multipathed iSCSI storage using IBM Storwize SAN. In Proxmox 6.4 which we use, there is a shared LVM created which stores VMs on all nodes. We didn't notice any performance...

Hello Two problems partly related. Problem 1: When you have a vm with a disk on lvm (not in a thin pool) the lv gets deactivated whenever you turn off the vm. This is not such a great idea because if you also have lvmcache enabled the dirty writeback blocks will not be committed from fast to...

HI all, I have a four node PVE cluster, single 500GB disk on each node. All nodes are configured with Ceph on lvm. The lvm is taking most of the disk, with only about 50GB left for local storage. I want to move a couple of VM disks from ceph to local. How can I shrink the Ceph OSD, then...

I run a proxmox 7 server with a ZFS storage. I recently installed oracle linux as a VM on it and since then I have problems with io-delay. As soon as I start this VM io-delay goes up to 80-90%. The server is neatly slow. I moved the disk to another storage (NFS) and io-delay went down to 1%...

Hello I installed new server of Proxmox. I would like to move my VMs from disk of my old server. Unfortunatelly, I don't know how to ucomplish. I have disks like this: root@local:/mnt/bak# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda ├─sda1...

Hi, How do i mount lvm disk used by VM on host machine, so i can copy files? The VM (Xpenology) is broken and I can't boot on it anymore. I had 2 4TB disk in RAID 1 mounted on it and I want to get back my data but I can't mount the LVM. (I'm only interested in Disk_1 and Disk_2) Here are...

Hi there, I have just finished setting up my second homelab host and come to the horrible realisation that my 2 x 2TB and 4TB disks are all LVM and have running VM's on. I tried to take a snapshot, only to realise that I cannot make a snapshot due to it being LVM on the disks. I would like to...

This is probably an FAQ, but I can't seem to find a straight forward approach for this: There's a container with a relatively small root disk on a relatively small LVM (on an internal disk) I successfully added a 2nd lvm for an external SSD following this approach Now how di I "give" the...

Hello, I'm going to install a new fresh Proxmox server for my homelab and I'd like to ask you suggestions to configure it in a proper way (I've already a Proxmox server I'd like to reconfigure from scratch). HW: CPU Intel Core i5 4460 (4c/4t) RAM 16GB 8x SATA3 ports (2 on the mobo and 4 on a...

Guten Morgen, ich habe eine LVM Festplatte zur hälfte an einen LXC Container durchgereicht. (Nextcloud). Nach einen Restore des LXC wird mir die Festplatte in Proxmox als "komplett Verfügbar" angezeigt. Also so, als wenn diese gar nicht durchgereicht wurde. In den Containereinstellungen von...
