LnxBil replied to the thread feature request: "LVMthin over iscsi" storage plugin.Although such a system is tempting, but no enterprise I know does this, everything is active/active and any software solution I came across claims it does that, but does not fullfill all HA requirements and zero data loss. There are also products... -
LnxBil replied to the thread free Starwind x Proxmox SAN storage plugin.That does not work like that. If you have a block storage for your VM, the block storage itself handels thin provisioning, e.g. if you have a disk with a lot of zeros on the disk, they will not be written. In the VM, you only have to check the...

JJohannes S replied to the thread Unterstützung für Proxmox VE 8 endet am 2026-08-31.Die eigentliche Frage ist, warum er nicht einfach nur ein bare-metal NAS laufen lässt, wo dann in docker-Containern auch alle sonstigen Dienste laufen. Den Usecase "möglichst wenig Wartungsaufwand" bedienen TrueNAS oder uNRAID nämlich deutlich...

Moin Wenn ich mal fragen darf: Du hast also einen Proxmox Host am laufen und zusätzlich auch noch eine extra Kiste mit Unraid? Oder wie ist das mit dem "nicht immer an wegen Stromverbrauch" jetzt zu verstehen? Und wenn dem so ist: Warum hast Du... -
Kkph replied to the thread Unable to delete backups, No space left on device.With the storage in Maintenace Mode (offline), neither GC nor Verify will run. This is with PBS 4.2.1 on PVE 9.2.3. I just made sure that none of my backup jobs would run while I performed the house-cleaning. As expected, there were warnings...

Aalain replied to the thread Ceph security issue CVE-2025-30156.I am on the Ceph users email list, and it seems the fix is not a simple update, and will not be trivial. You have to use new authentication keys, aes256k, and rotate the keys used, and for that (for rbd storage at least), shutdown all VMs. And...

Rr0bb1 posted the thread Proxmox → ZFS → VirtIO-SCSI → NFS a viable HA storage architecture for ~100 VMs? in Proxmox VE: Installation and configuration.## Looking for feedback on a Proxmox + ZFS + VirtIO-SCSI + NFS HA storage architecture Hello, I am looking for some feedback on the feasibility of a storage architecture we are considering for a small startup environment. We are trying to...

Lluckman212 replied to the thread pmxcfs spamming into /var/log/syslog.I'm getting these too, only on 1 node of my 3-node cluster (PVE 9.2.11) Is echo "1" >/etc/pve/.debug still suggested?

Yes, but not every single time. Depends essentially on the size of the datastore, how much work PBS has to do (i.e. backup once a day vs once an hour, many replicas, many verify, etc), and how much time you have to run GC, which is the task that... -
Aalma21 replied to the thread feature request: "LVMthin over iscsi" storage plugin.LVM thin is per se not cluster aware ... this is correct .... but the idea is to have e.g. 2 storage/frontend VM "controllers" to your SAN(s) which are running in a dedicated HA active/passive (LVM thin/iscsi target) pacemaker cluster under...

Ich upgrade regelmäßig PVE in Unternehmen wo es keine Unterbrechungen geben darf. Solange man die Anleitung befolgt und Warnmeldungen auch beachtet / abarbeitet und nicht ignoriert ist noch nie etwas schief gegangen. Die Kunst ist das lesen, wer...

Was ist daran doof? Warum bitte sollten die Entwickler weiter Updates bereitstellen, weil Leute zu faul zum updaten sind? Das Basisystem von Debian kriegt ja eh schon keine Updates mehr, das heißt also die Entwickler müssten den Aufwand für...

Maximiliano replied to the thread VM becomes unresponsive during Veeam backup.Hello, Would it be possible for the affected people in this thread to tell me 1. On what storages are the disk images of the affected VMs? Ceph? iscsi? etc. 2. Where are Veeam backups for this VM being stored? On which storage? 3. Please take a... -
Iitsnota2ma posted the thread Has anyone tried Ubiquiti's ENAS for ProxMox's storage array? in Proxmox VE: Installation and configuration.I recently installed Ubiquiti's ENAS as a replacement for my Equallogic SAN. And the price is unbeatable. Now, is it as robust as my Equallogic SAN?? I do not know, we will find out. With that said, at $4000 for the chassis, I can by a spare and...

Llonger replied to the thread feature request: "LVMthin over iscsi" storage plugin.I am also not sure if LVM-Thin can be safely shared between different nodes? Currently if the backend storage support thin-provisioning and discard, then (I think) you are more less having the same features as if its "LVMthin over iscsi". I mean...

CCarstenGrohmann posted the thread I/O Write Errors in VM running on NetApp NFS with sparsefile support enabled (DEALLOCATE returns NFS4ERR_IO) in Proxmox VE: Installation and configuration.I run a stacked setup with Debian 13 on PVE (hostname pve150) on PVE and use an NFS v4.2 datastore backed by a NetApp ONTAP Simulator. I see some serious errors in my VM at 14:19 CEST: [ 43.534144] I/O error, dev sda, sector 812584 op...

Iitsnota2ma replied to the thread free Starwind x Proxmox SAN storage plugin.Damien, I struggled with iSCSI and my Equallogic SAN. I recently moved to a Ubiquiti ENAS, which is ZFS and supports NFS for thin provisioning and snapshots. It also supports iSCSI, which I tested the connection, but decided on NFS. What is nice...

Mmohsin045 posted the thread iSCSI storage performance drops after firewall rule changes – anyone else? in Proxmox VE: Networking and Firewall.Now we're seeing random performance drops on the iSCSI connections – latency spikes, occasional timeouts. The VMs are still running but storage performance is inconsistent. What we've checked: iSCSI network is on a separate VLAN Firewall rules...
