TLDR: Ceph vs ZFS: advantages and disadvantages? Looking for thoughts on implementing a shared filesystem in a cluster with 3 nodes. They all serve a mix of websites for clients that should be served with minimal downtime, and some infrastructure nodes such as Ansible and pfSense, as well as...

I was running VMs and having some trouble choosing the storage, because whenever I chose a storage volume, it seemed the files remained in the other volume. I've moved the VM to local (another location), and touched this test file in the directory to see if it behaved the same in the...

I have a VM on a node, and I see in storage that it takes up to 10x the size (maybe more). These are the files for a 65GB VM: root@host:/# cd /mnt/store/images/110 root@host:/mnt/store/images/110# ls -l total 147052708 -rw-r--r-- 1 root root 68730355712 Oct 20 12:54 vm-110-disk-0.qcow2...

Coming from this thread, for information purposes. In order to get this done, I migrated the VM to another node, to avoid the downtime. Migrating back, I got this error: 2020-10-06 19:32:44 ERROR: online migrate failure - aborting 2020-10-06 19:32:44 aborting phase 2 - cleanup resources...

Hello, I've enabled Hardware Virtualization on a single node, by following the instructions over here: https://pve.proxmox.com/wiki/Nested_Virtualization At one point, the instructions state to unload and load the module: # modprobe -r kvm_intel # modprobe kvm_intel I did this, but I can't...

Hello, would appreciate any pointers in how to do this. I created a Proxmox cluster with three nodes, with public IP addresses. Let's say: 74.6.143.25 74.6.143.26 74.6.143.27 I would like to change them to an internal network, behind a switch. Maybe to something like: 192.168.1.25...

I'm trying to secure my machines, and disallow remote root logins. I tried setting it to no, but when I tried migrating a machine to another node on the cluster, I can't. Can I have "PermitRootLogin no"? How about "PermitRootLogin proibit-password"? I figure some of these would make the...
