I have the high CPU usage in the virtual machine, not in the host machine, so I am not sure how this can help (Cpanel runs 2.4.x kernels) The virtual machine is not reactive and doesn´t log anything, I have to reset it or stop it (shutdown doesn´t work) and start it again. Where do I look for...

Hi, I migrated two proxmox virtual machines from Proxmox 4.4 to 5.1. I took advantage and I migrated to ZFS. The old server had SATA disks while the new one has SSD disks. I have only two VPS running in this server. Both running Centos 6.9, one plesk and the other one Cpanel. The Plesk...

Many thanks! You have been very helpful! root@server:~# zfs get reservation,refreservation -r rpool/data NAME PROPERTY VALUE SOURCE rpool/data reservation none default rpool/data refreservation none default...

Both two VMs come from the same proxmox server. If I set to zfs set refreservation=none it will decrease the space used or there isn´t a way back?

Why those different values? I didn´t do anything different when I imported the raw disks

If you meant the property reservation, here we go: root@server:~# zfs get reservation,refreservation -r rpool/data NAME PROPERTY VALUE SOURCE rpool/data reservation none default rpool/data refreservation none...

I tried that too, same thing.

When I run that command I get No datasets available

I have set up ZFS on two nodes. I am googling around to get any tutorial to do what I want, which is to perform a daily sync and performing a backup in the second node. I see people complaining about snapshots clean up but I don´t find any information of how to do it. If I don´t have much...

Dear all, Is it advisable to use sparse on ZFS pools performance wise? And compression? Which kind of compression? Can I change a zpool to sparse on the fly or do I need to turn off all VMs before doing so? Why a virtual disk shows as 60G when originally It was 36 Gb in raw format? NAME...

I ended up cloning the qcow2 disk with gparted into a second disk I created. For the record, make sure to copy the MBR. Now I have a qcow2 with a smaller disk size.

Ok, I have installed ZFS at OVH (they have an installer with Proxmox 5.1). They create a rpool zfs volume. Within they create: /rpool/data /rpool/ROOT /rpool/ROOT/pve-1 but I don´t see them when I run zpool list. It´s a little bit confusing coming from file-based system where all images of...

I have solved it creating a new virtual disk with the final size you want. Then you can clone the original qcow2 disk with gparted. Make sure you copy the MBR with: dd if=/dev/sda of=/dev/sdb bs=446 count=1 or dd if=/dev/sda of=/mnt/mbr.bin bs=446 count=1 dd if=/mnt/mbr.bin of=/dev/sdb...

It´s not working for me...how do I configure my linux guest?

I have installed Proxmox 5.1. Can I have two vmbr ? One for the bridge IPs and another for NAT? I want to have two VMs that only have access to Internet but not reachable from outside. Right now I have: # This file describes the network interfaces available on your system # and how to activate...

But what about what am I asking? Why am I not getting the real size in my qcow2 disks? Any special settings for SSD?

Hi, I am migrating from a server with Proxmox 4.4-18 with SATA drives to a Proxmox 5.1-36 with SSD drives. I am trying to get the best in performance. I already split OS and data disk drives so /home folder is not being backed up by Proxmox, only OS. Filesystem Size Used Avail Use%...
