Hello everybody, I wanted to install a self-hosted instance of gitlab on my proxmox node and I wanted to avoid a VM because I wanted to avoid to run the gitlab database inside a virtual disk and I wanted to avoid a privileged container because the gitlab webserver could be faced to the public...

I'm having some hardware support problems on PVE 7.3 and 7.4 and I was guessing if I could upgrade my kernel or not. Because, as we already know ZFS is not thightly integrated with linux kernel, so one has to be careful to no upgrade the kernel to an unsupported version for the current zfs...

When I SSH into a pct autocomplete works good, when I enter with pct enter xxx command, it doesn't work at all. I have tried to find info online but I have found nothing. PVE v 7.3-4.

There is a way to continue PVE-ZFS storage replication as usually after rolling back a guest without having to do a full/base synchronization? I haven't been able and I haven't find nothing on the internet neither. I have tried: to prune dataset snapshots in the hot spare machine to match the...

Syncoid (dataset synchronization between two different machines) and Sanoid (creation and prune of snapshots) are two ZFS (high-level) tools that combined give you hot spares (syncoid) and backups (sanoid) to roll back to them if necessary. Proxmox has the storage replication feature (pvesr)...

Hello everybody, After tinkering a little big with PBS, I have uninstalled it and installed PVE too in my second node. Then I have tried to set up replication between both of my nodes. Everthing worked well at the end. Then I tried migrating a CT and a VM to my new node. After that, in the web...

I have a single 6.4-15 proxmox node with some containers and VM. For all my containers console look like: For all my VM I can only write the following characters: I can't write "/", which limits a lot to navigate through the FS or to set IP/CIDR. This is locking me out of a backuped VM...

Searching info about containers vs VM, I'm reading that not everything can be run inside a container but they don't specify why (?) or that some kernel modules can be difficult or impossible to load; but I'm struggling to find a list or some examples of what can't be run inside a container and...

I have a PVE node with some CT & VM on ZFS. The second ones with thin provisioning on ZVOLs. Now I have installed PBS in another computer to learn how to backup my CT/VM. Everything works flawless. The problem it's when I go into PVE GUI -> PBS storage -> Backups -> SomeVMwithBigVirtualDrive ->...

Hello everybody, I want to benchmark my ZFS pools in a server that it's already running with data (mostly testing, but I don't want to lose it). For that purpose I have found =278bafe4f7648fa8072a76aebfd271e2']this, a ZFS benchmark done by proxmox team. So it looks like a great fit. They are...

I thought that it was true, but after reading some answers in this thread now I have doubts. The real reason why I want to know it's because of the full_page_writes parameter in postgresql DB. Setting it to off improves the performance greatly (almost x2) but for non COW FS keeps the DB in a...

Hello, I'm reading the proxmox documentation chapter 16, about backups and the VM backup - snapshot mode says: It's talking about a inconsistency risk that I don't know if it's properly explained. At least for me it has left a lot of doubts after reading it (probably because I'm a noob): What...

Hello, I have a proxmox (v5.4 I think) machine installed on ZFS, including the root filesystem. Then, quoting proxmox wiki, it should have been installed with systemd-boot instead of grub2. The thing is that the machine has grub2 (don't know why, I have inherited it like that) and after...

Hello everybody, I have a proxmox cluster of a single node and I want to start a new VM with a PostgreSQL and TimescaleDB and after a lot of reading about how to tune ZFS volumes for this purpose I still have some doubts with the cache options. We have 3 caches: The proxmox one (ARC), the linux...

Hello everybody, Right now I have a 4TB zvol that is attached to a VM that works as a fileserver over NFS/SAMBA. There are some issues with this zvol configuration (mainly related with volblocksize) and I would like to create a new one with the right config to replace the old one. This zvol is...

Hello everybody, I have a zvol with a volsize of 3.91T. This zvol is attached as a data disk to a VM that works as fileserver (SAMBA/NFS). Here you have the details of df -hT from inside the VM: 2.4T used from 3.9. The zvol has volblocksize = 8K, and is on a pool with only one RAIDz-1 of four...

Hello everybody, I have "inherited" a simple proxmox cluster with only one cluster, and I'm doing my best to catch up, reading the wiki, doc and forum threads. But there is something I still can't understand, that is the ZFS and proxmox storages layout. In the system there are two 1TB SSD and...
