The short story:
In proxmox 6 fallocate: fallocate failed: Operation not supported

The long story:
Sometimes I can't start my virtual machine because Proxmox says that there is not enough memory space (and it is very strange because I have a server with 16GB of RAM and my KVM is configured to use only 8GB) .

I installed Proxmox v6 in raid-0 zfs and noticed that no swap file was created (and it is very very strange!).

I thought of creating one in the hope of solving the problem but I encountered another error: it is not possible to use the "fallocate" command.

To reproduce the problem of not starting the KVM it is sufficient to do so:

  1. launch Proxmox;
  2. make a copy from one server to another with the "scp" command of a backup file of the kvm of at least 10 GB file;
  3. restore the kvm on the server in use;
  4. start the kvm and you'll meet the error;
Best regards,
E. Bruno.
zfs will use half of memory by default for his buffer cache. (and linux kernel can't retreive it like classic linux buffer memory)

until someone more knowledgable answers : that particular file is not of much importance for your install, i believe it is responsible for displaying the welcome message on the console after reboot (smt like : you can now connect to the webinterface at https://192.168.0.1:8006 ).
Fine to keep the existing file.

Unable to install proxmox ve6.0
When I installed proxmox6.0 on the Huawei RH2288V3 server, I always stayed on the "END USER LICENSE AGREEMENT (EULA)" interface. I could not click the "i agree" button, and the installation could not be continued. I have collected some error messages. What should I do?
But test version 5.4, can install it normally!

@gyq just an idea, can you try using the keyboard to see if that works, Alt+(underlined letter).

Of course you will have to run the installer somewhere else to see what you have to press in the real server

Please open a fresh thread for specific problems!

Apart from that: see this thread for a potential explanation: [URL]https://zfsonlinux.topicbox.com/groups/zfs-discuss/Tcc78c13dd9db7ae8-M5d8b18dcd2b271fa9975888a[/URL]

@Stoiko Ivanov Thanks for the explanation. It seems that consumer based SSD will not have TRIM enable for LSI HBA in IT mode. Only enterprise SSD will work.

Sorry for not open a fresh thread.

Since upgrading to 6.0 I have noticed that my 4-node cluster has become unstable. At random times up to 3 of the 4 nodes will suddenly drop all connections and appear as if they have rebooted. However inspecting my machines iDRAC logs no reboots or power issues occur. It would appear that this may be related to https://bugzilla.proxmox.com/show_bug.cgi?id=2326 as what is described there is exactly what is happening to my cluster as well. Does anyone know if there are any fixes for this yet? I need my cluster to be stable again, its really starting to annoy me that it keeps randomly restarting!!
