ZFS is a combined file system and logical volume manager designed by Sun Microsystems.
Starting with Proxmox VE 3. There is no need for manually compile ZFS modules - all packages are included. By using ZFS, its possible to achieve maximum enterprise features with low budget hardware, but also high performance systems by leveraging SSD caching or even SSD only setups.
ZFS can replace cost intense hardware raid cards by moderate CPU and memory load combined with easy management. ZFS depends heavily on memory, so you need at least 8GB to start. This can increase the overall performance significantly. You need to select the RAID type at installation time:. The capacity of such volume is the sum of the capacities of all disks. But RAID0 does not add any redundancy, so the failure of a single drive makes the volume unusable. Data is written identically to all disks.
This mode requires at least 2 disks with the same size. The resulting capacity is that of a single disk. After installation, you can view your ZFS pool status using the zpool command:. The zfs command is used configure and manage your ZFS file systems. The following command lists all file systems after installation:.
There are a few factors to take into consideration when choosing the layout of a ZFS pool. The basic building block of a ZFS pool is the virtual device, or vdev. All vdevs in a pool are used equally and the data is striped among them RAID0. Check the zpool 8 manpage for more details on vdevs.
Each vdev type has different performance behaviors. A mirror vdev RAID1 will approximately behave like a single disk in regards to both parameters when writing data.Forums New posts Search forums.

A 6 drive RaidZ2 pool is attached to the H Finally, one VM is xpenology since it was quick and easy to get our IP cameras running and Synology's mobile camera app is pretty good. For step 4, I am getting confused as to "where" it is best to configure nfs-server and samba, and how to best configure storage for the LXC containers.Forums New posts Search forums.
You should upgrade or use an alternative browser. Dec 30, 10 1 1 I need a little help to figure out how to mount my zfs pool to a container. Apr 28, 16, Austria www. Tassir Member. Feb 22, 6 1 23 Tassir said:. Is there any option for some kind of a recursive bind mount or something?
You simply mount everything you need on the host side. You then see the same inside the container. That is how bind mounts work. Jun 23, 92 Bind mounts are not recursive, so you need to include mountpoints "inside" bind mounts in the config separately. Thanks guys, I added a separate bind for each subvolume and it is working as expected. My zfs pool is on Proxmox itself but I got samba running in a container hence i needed to pass all the subvolumes to itwhere are you running samba?

Apr 17, 31 I took a slightly different route.Containers are a lightweight alternative to fully virtualized machines VMs. They use the kernel of the host system that they run on, instead of emulating a full operating system OS. This means that containers can access resources on the host system directly.
The runtime costs for containers is low, usually negligible. However, there are some drawbacks that need be considered:. Only Linux distributions can be run in Proxmox Containers. For security reasons, access to host resources needs to be restricted. Therefore, containers run in their own separate namespaces. Additionally some syscalls user space requests to the Linux kernel are not allowed within containers.
Containers are tightly integrated with Proxmox VE. This means that they are aware of the cluster setup, and they can use the same network and storage resources as virtual machines. Our primary goal is to offer an environment that provides the benefits of using a VM, but without the additional overhead. Proxmox VE itself provides a variety of basic templates for the most common Linux distributions. Additionally, TurnKey Linux container templates are also available to download.
The list of available templates is updated daily through the pve-daily-update timer. You can also trigger an update manually by executing:. You can restrict this large list by specifying the section you are interested in, for example basic system images:. Before you can use such a template, you need to download them into one of your storages. For clustered installations, it is preferred to use a shared storage so that all nodes can access those images.
You are now ready to create containers using that image, and you can list all downloaded images on storage local with:. The above command shows you the full Proxmox VE volume identifiers. They include the storage name, and most other Proxmox VE commands can use them. For example you can delete that image later with:.
Unprivileged container : this option allows to choose at creation time if you want to create a privileged or unprivileged container. Unprivileged containers use a new kernel feature called user namespaces. The root UID 0 inside the container is mapped to an unprivileged user outside the container.
This means that most security issues container escape, resource abuse, etc. The LXC team thinks unprivileged containers are safe by design. Security in containers is achieved by using mandatory access control AppArmor restrictions, seccomp filters and Linux kernel namespaces.
The LXC team considers this kind of container as unsafe, and they will not consider new container escape exploits to be security issues worthy of a CVE and quick fix. You can restrict the number of visible CPUs inside the container using the cores option.
This is implemented using the Linux cpuset cgroup c ontrol group. A special task inside pvestatd tries to distribute running containers among available CPUs periodically. To view the assigned CPUs run the following command:. Containers use the host kernel directly. All tasks inside a container are handled by the host CPU scheduler. You can use this option to further limit assigned CPU time.
Please note that this is a floating point number, so it is perfectly valid to assign two cores to a container, but restrict overall CPU consumption to half a core. This is a relative weight passed to the kernel scheduler. The larger the number is, the more CPU time this container gets.Forums New posts Search forums.

PVE doesn't do recursive bind mounts, so when you mount the dataPool it only mounts that filesystem within the container, including the empty media directory that serves as a mount point, but it doesn't mount the filesystem that is mounted there.Home Networking: 100TB 10Gbit Server - Installing Proxmox and basic ZFS tutorial
So you were already on point in your second post and I fear you'll have to mount each filesystem separately. Feel free to subscribe to this bug report for updates there's also an experimental patch available. Reactions: arneKlaver.

The Predictions Board is a powerful and important tool to help you measure and improve your systems and methods of play. It is a one-of-a-kind feature on the Internet, available only at Lottery Post.
Every Lottery Post member can post predictions. The system saves of all predictions and actual results, so you can analyze your prediction accuracy over time, as well as that of the other members. The prize amounts awarded for prediction wins are standardized amounts for each game type. For example, the 4-of-6 prize for Pick 6 in New Jersey is the same as the 4-of-6 prize amount for Pick 6 in every other state. A straight Pick 3 win in California is the same amount as a straight hit in any other state.
This prize standardization lets our members compare prize ratios between states. Also, please take a few moments and review the rules for posting at Lottery Post.
