storage

Hello, I installed Proxmox VE using two disks with ZFS RAID1 (mirror) for lab testing From my testing: If I unplug or fail disk 2, the system still works fine and Proxmox is accessible. But if I unplug or fail disk 1, the system will not boot and Proxmox becomes inaccessible, even though disk...

First, let me contextualize our set-up: We have a 3 node cluster, where we will be using CEPH for storage hyperconvergence. We are familiarizing ourselves with CEPH and would love to have someone more experienced chiming in: All of our storage hardware are SSDs. (24x 2TB NVMe, 8 per server)...

Hey everyone, I'd appreciate some advice on properly partitioning and configuring my Proxmox VM/CT & storage server. I want to make sure I'm following best practices before I start deploying VMs and containers. Here's what I'm working with: Hardware Setup: AMD 3950X with 64GB RAM...

I have an Ubuntu Server VM that I initially gave 64GB to but it has quickly outgrown it. The local-lvm that it's using for the VM disk has extra space on it so I'd like to expand the VM Disk and then somehow also expand the disk inside of the virtual machine itself. All without losing data, of...

I really tried to find an existing thread, but everything I find is either related to the main/boot pool, or adding an encrypted dataset only, so I figured I write down my steps for my own documentation and maybe it'll help someone else out too. This is for when you already have a PVE set up...

Good afternoon, everyone! I’m facing an issue with Proxmox. I have an HPE MSA 1050 SAN configured for HA, and I’m not able to create snapshots of the VMs stored on this disk. OBS*: From what I’ve read in some documents and forum threads, it seems that LVM does not support snapshots. Is there...

!!! 1.Hint: This Thread is not for Ceph fan boys. Go away! !!!! Occasion: In the Thread "Vote for Feature in ZFS-over-ISCSI" my one (the word "one" is always related to a human being, not a matter or person or number) had to put question marks in the row "own build with free software possible"...

Hi. I've recently added an LVM thick storage to my PVE cluster which is a LUN shared between 4 of 5 nodes and everything works just fine except VM migration. I migrated VM from the 5th node which only has local storage to different node and shared LVM storage. Now I can't migrate it back. When...

Hello everyone, I am experiencing an issue with my ZFS pool usage reporting. My ZFS pool "Crucial" is showing 71.69% used (663.64 GB of 925.73 GB). However, this pool only hosts 3 virtual machine disks: VM100: 274.88 GB VM101: 90.19 GB VM102: 90.19 GB This gives a total of 455.26 GB, which is...

Hi, as i've stated in the title i'm having some problems which i can't really pinpoint on a specific server. The server has been off for around 10 days during summer vacations, and when i turned it back on one of the VMs didn't want to turn on. After a reboot, the incriminated vm booted without...

Target audience: Beginners There are no secret tips-n-tricks here, just basic knowledge. Precondition you have an intact PVE installation, be it a single computer or a cluster with several nodes; I am using the current 9.x release you have HDDs which may contain old data - that data will get...

Hi folks, I'm going to be building a new Epyc based server this week, and I have some questions concerning ZFS pools under Proxmox. Previously, I've done most ZFS related things with TrueNAS, first virtualized, and now bare-metal. I have two TrueNAS machines that handle all typical NAS duties...

Hi! I'm sorry for my English right away)) Please help me set up storage in my configuration, because I don't understand how to proceed correctly. I have a cluster of 3 PVE hosts. I also have an IBM Storwize external storage. On Storwize, I give 1 volume to the PVE hosts. Each PVE host is...

Hi Everyone, I'm excited to share a deep dive into one of the notable new feature in PVE9: the enhanced snapshot functionality designed for legacy SANs. This feature represents a meaningful step forward in expanding PVE's compatibility with traditional enterprise storage setups, something many...

I want to delete the one labeled "local without messing up the "Local-Storage". Any help will be appreciated. Thanks David root@fcc-node-01:~# pvesm status NameTypeStatusTotalUsedAvailable% Used...

Hello, pve-manager/8.4.5/57892e8e686cb35b Linux 6.8.12-12-pve (2025-07-14T13:20Z) I have noticed an issue with displaying the disk size in Proxmox after adding space to an existing disk in a VM configuration. When creating the disk, the size is specified in GiB (binary units), but after adding...

Hi All, While setting up automated testing for PVE 9, we observed that several udev properties were missing from SCSI block devices. After some investigation, we traced the issue to a regression in the sg_inq tool (part of sg3_utils). The bug was introduced during a refactoring effort related...

Hello, I am looking for assistance with accessing my VMs now that I ran: zpool destroy - f <MYZFS> I thought all my VMs were on a separate SSD... So, I had a pfsense VM and I now can't access my workstation through that network after running zpool destroy. I hooked up to the PVE machine and...

I’m currently working for a company that runs a vCenter cluster using 1 Gb/s iSCSI storage on Synology SANs. Everything works perfectly snapshots, thin provisioning, multipath, etc. We’re now looking to migrate to Proxmox, and the big question is: how can we achieve the same storage capabilities...

Hallo Leute, ich habe einen ziemlich chaotischen ESXi-Server, auf dem wirklich viel Müll liegt und alles durcheinander ist. Jetzt wollte ich erstmal alle VMs von dort importieren. Am Anfang gab es Probleme, ESXi als Storage hinzuzufügen, weil eine VM ein Laufwerk im datastore2 eingebunden hatte...
