The main bottleneck with hard drives is that they’re relatively slow. So ~100 IOPS peak and maybe 5-10MB/s in random read write scenarios. You need to read/write 100TB/day -> 1200MB/sec -> you need 300 disks just to keep up multiplied by the... -
Lvim /etc/pve/storage.cfg and replace old => new

But there's already a thin pool on it? You can add it via Datacenter > Storage > LVM-Thin. You might have to rename the duplicate group though. ZFS might be another (better, IMO) option depending on what you do. Edit: Even better. Instead of... -

UdoB replied to the thread Additional Network configuration.Well, I can not write a dedicated complete guide for that setup. My answers are always only snippets of the whole picture. (And: I do not use pfSense...) If #4 is still valid: yes. But in #7 you show that vmbr1 exists with enp5s0. Does that...

OHello everyone, I have a question regarding the permissions of API tokens used in sync jobs between PBS servers. Until now, I was adding my remote server and running my sync jobs with a token derived from the root@pam user (so bad !). So I tried...

JWiping is in the GUI too - no need for CLI. (<node> --> Disks --> select the device --> Wipe Disk)

JLots do. I also always have to suggest this as well. If it were such a bad idea local-zfs wouldn't use it. I made a ticket in argument of changing the default if you care. I have a little snippet here which might be useful if you still need to...

IIT_Tooling replied to the thread GPU Passthrough Problem After Upgrading to Proxmox 9.2.3. [RESOLVED].Hi Jonas, thanks for the response. I researched the Proxmox Documentation Site at https://pve.proxmox.com/wiki/PCI_Passthrough and identified the recommended solution as follows: Fix H100 GPU passthrough by adding phys-bits=host to the...

LI can concur that the wiki post is hot garbage and you will ruin your Proxmox host if you try this. Good thing I tried this in a lab first. Encountering the same issue where the nodes folder contents refused to copy. Gave it another reboot, and...

You wipe the hdd ( all data on it will be lost though) and afterwards create a lvm/thin or zfs pool from the GUI.

LRe: [SOLVED] Proxmox node name change Hello, Actually, that hostname change caused me a lot of troubles. Indeed, when you change these files your hostname would change but: 1) It creates a separate datacentre (called with the new name) 2) All...

Wwickeren replied to the thread redundancy for CEPH and SDN.Tnx for you reply, gonna look further into it. I didn't see the first post so I made a new one. Then they eventually both showed... Not sure how to close or delete the other one.

bbgeek17 replied to the thread Windows Failover Cluster.For lab purposes you can achieve QCOW sharing by forcing QCOW disk assignment to two VMs via "qm set". However, this would be against both standard PVE practices and certainly against the MSFT cluster qualification, and as such - not suitable for... -
bbgeek17 reacted to aaron's post in the thread HA fencing with softdog vs IPMI watchdog — which one is actually used when both are configured? with
Like.
I recommend to stick with the soft watchdog. It works well and you avoid any issues due to questionable quality of OOBM hardware and software ;) -
JJohannes S replied to the thread ZFS raidz1 and snapshots, again.I agree. First performance and iops will suffer compared to a mirror or striped setup, second it will lead to waste due to padding see: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/ Another issue are the large...

Jbefore we dive too deep into snapshots and their storage consumption, we should IMHO look first at two more important issues. I would argue that running RAIDZ1 is unsafe. Dell marked RAID5 to be against best practice and unsafe something around...

JTherefore I did not specify the disk. If you do, you need -r as option So you missed checking the thin provision box in your storage configuration in the PVE UI:
