Just because Proxmox VE allows you to install it this way does not mean it is supported. (And also it is not supported at all.)
It is well documented that even though hardware raid cards do not prevent you from using ZFS, it will create issues if...
And also would it be possible to maybe get one extra 4TB drive?
With 4 drives you can use ZFS mirror (Raid 1) instead of Raid5/RaidZ1
In my personal experience, it is not worth the trouble of dealing with anything other then mirrors unless the...
There is a RAID card installed but I did not setup an array with the card. I think the proxmox install allowed me direct access to the drives and installed the software RAID with zfs. Would that mean the card is compatible?
Do you have a raid card installed?
Raid cards are most of the time NOT compatible with ZFS. (As ZFS requires direct disk access and not all raid cards allow that.)
Unknown, especially since you posted output from the cluster in a healthy state. size 4 is generally a bad idea (even number; the last copy offers no utility), but it should not cause you any issues like this, especially with only one node out...
Hi @admin20, welcome to the forum.
You can, but you don't strictly need to. The ESX Migration tool uses ESXi API to extract data from ESXi and then transfer it to the PVE. That obviously means that you need somewhere to put that data in PVE. It...
It is a shared lun that seems to be working fully across the nodes in my custer, for migrating I was trying to move the active VM not the underlying disks. Live migration works for my other VM's, but this one because of the failed snapshot...
Hi All,
Recently our small MSP has decided to move away from ESXI and move to Proxmox for our client server deployments. As I am heading up new server projects, I am going through learning this new environment and need some direction as to what...
When I happen to severely "spoil" my console or ssh session (e.g. catting some binary to the screen) and stty sane isn't able to reset it, I hit:
echo Ctrl-v Esc c
which I input in the following way:
echo
space
keeping left Ctrl pressed press...
Hi All,
I encountered a severe issue today - I run a PVE 9.1.2 with ZFS as local filesystem.
On top I have a LXC container, inside this container I have some files with "broken" filenames, likely due to some UTF8 problems - the origin of the...
Hello,
> reduce ZFS arc to maybe 1/3 or 1/4 of RAM (https://pve.proxmox.com/wiki/ZFS_on_Linux#sysadmin_zfs_limit_memory_usage)
Note that new Proxmox VE installs starting from 8.1(see the changelog [1] for more details) will by default allocate...
I recently had to move my ProxMox instance to a new computer as the fan in my HP Prodesk was going out causing the CPU to overheat and shutdown. I moved the Hard Drive from my Prodesk into an Intel Nuc with the same amount of memory and a newer...
(FYI, I already filed a bug report for the same issue to OpenZFS here: https://github.com/openzfs/zfs/issues/18094. I am sharing here as well since I imagine this is of interest of Proxmox community as well)
I noticed kernel task hangups in...
As was mentioned, getting new drive is "nice" but not really required.
With a reputable enterprise flash drive, getting it used is fine. I have used 5-year-old Intel enterprise SSDs and they still show 100% life.
At home, I use Intel Optane...

Proxmox VE and OMV stall (freeze) when backup job run.
Hi,
I'm running Openmediavault (OMV) already for a long time as an VM guest at Proxmox VE (PVE) host, at an HP Proliant GEN8 microserver (XEON E3-1260L 16GB).
Attempts to run PVE with...
