But wouldn't a default raid1 btrfs be like raidz1 in zfs or would you need raid5 in btrfs to have something similar?
RAID 1, BTRFS or regualar, is a mirror of two disks. RAIDz1 is like RAID5, RAIDz2 is like RAID6 and for RAIDz3 there is no RAIDn equivalent.
Updating to the latest PVE kernel worked like a charm. Thanks for the timely implementation ryecoaaron!
Wondering what you are willing to invest into this project as well as how many, and what kind of storage media you want to use.
For a very power consumption friendly x86/amd64 system with the ability to use 2x SATA drives as well as 1x M.2 NVME/or a M.2 to 6x SATA controller have a look at my signature.
Do you want to get rid of that specific update notification?
openmediavault-compose 7.1.2
or any kind of update notification?
Since you explicitly mentioned that you use Portainer to manage your Docker containers, I would only think of the Compose plugin. The answer in this case would be as simple as: uninstall it because you don't need it.
And if I'm wrong in my assumption, votdev has already clarified your concern.
Then I have no idea offhand.
Maybe a silly question, but have you defined the OS drive in the BIOS as the one to boot from?
Minfred, if you're interested in buying an Odroid H3(+), check out Antratek's store. That's the source where I bought mine, as well as eMMC, SATA data and power cables, and the power supply.
Since you live in DE like me, this is the cheapest source nearby to get these parts. They have branches in BE, DE and NL so you don't have to pay any fees. Shipping is also free. Don't buy RAM modules there! They are way too expensive - better look at Geizhals.de.
The DAS enclosures you've listed above seam to be desktop kind devices and quite expensive. Are you tied to this form factor? If not, I would take a look at some refurbished 19" storage boxes to house your data drives.
Those come with SATA/SAS backplanes. So the device which houses your OMV VM needs a HBA with external connectors which needs to be routed to the backplane of the 19" storage enclosure.
As I'm very satisfied with how the Odroid H3+ performs I've ordered a second one to replace my current backup server. In the end I will power both H3+ including the connected devices (RAM, eMMCs, NVMes, 2.5" SSDs, Noctua NF-A14) using a single Corsair RM550x ATX PSU.
As far as the housings are concerned, I am thinking about the right way. They will definitely not be from Hardkernel.
Option #1:
DIY using 20x20/MakerBeam extruded aluminum as a framework which is covered with poly carbonate sheets, the grooves of the respective aluminum profiles are suitable for this.
Option #2
Ready-made solution using an existing Chieftec Cube CI-01B, which accommodates both H3+ including the storage media and the Corsair RM550x.
Do you have measured this consumption by yourself with a trustworthy device?
To measure the power consumption, I used a Voltcraft SEM600 socket adapter, which provides a fairly accurate measurement.
I thought that SSDs by themself drawing 1-2W each and that and x86-cpu can't be that frugal (The Odroid H3 seems also have an TPB of 10W, the hardkernel poweradapter has max. 60W),
that would be a crucial criteria for me to go for the Odroid.
Hardkernel offers two kinds of PSUs:
1. 15V 4A, able powering Odroid H3+, 1x eMMC, 1x NVMe, 2x SSD, 2x SO-DIMM
2. 19V 7A, needed if you want to supply power to 2x 3.5" HDD instead of 2x 2.5" SSD
You can also use a standard PC PSU instead of the two mentioned above. To power the H3(+) all that's needed is a SATA power to 5.5/2.1 barrel connector. Another option for using a standard PC PSU would be using one of those connectors for which you need to cut off e. g. a 4-Pin Molex connector and mount it's wires to the plug. How it's done you can see in the video if posted in my first entry in this topic.
Important in that case is, to NOT use the H3(+) JST connectors for powering any kind of 2.5"/3.5" drive.
Currently I'm using the 15V 4A PSU from Hardkernel. Waiting for the adapter mentioned above. Want to use a Corsair RM550x Series 2021 which I have. It's one of the best for low power setups, sadly no longer buyable. I bet that using this PSU will lower idle power consumption a little more. Don't thing that the plugs offered buy Hardkernel are power efficient.
The case is ugly, but cheap and will be the saving part to the higher price of the board.
Totally true! Because of the I will make my own case using either 2020 extruded aluminum or smaller version made by MakerBeam.
Is the performance nearly comparable to the N100?
the H3+ N6005 at 195usd is comparable to the N100
Complete posting of olduser you can find here.
Or have a look e. g. here and decide yourself.
How do you flashed the eMMC with omv? Can this be done via the board and a usbstick or do you need an eMMC-writer?
Yes, I'm running OMV with my Odroid H3+. Simply mount the eMMC on the Odroid, boot the installation media (USB stick) and install OMV on to the eMMC drive.
Edit #1
Additional information:
You could also mount the H3(+) within a default PC case of your liking using a 3D printed adapter like this one.
Edit #2
Take a look at the following YT playlist to get some inspirations.
Edit #3
Added an alternative solution for using standard (Flex-) ATX PSUs
Some other options to think about may be:
1. Odroid H3 w/ Intel Celeron (N5105)
2. Odroid H3+ w/ Intel Intel Pentium Silver (N6005)
Both have a PCIe 3.0 x4 slot for NVMe or other components, 2x 2.5Gbit NIC, 2x SATA 3.0, 1x eMMC
Currently I'm tinkering with a H3+ with the following configuration:
- 2x Crucial 16GB SO-DIMM (CT16G4SFRA32A)
- 1x Samsung 970 EVO Plus 250GB; contains Gitea, Homer, Paperless-ngx, Syncthing, Unifi Network Application and Wiki.js Docker containers
- 2x Samsung 870 EVO 2TB (ZFS mirror); NAS storage
- 1x 32GB eMMC; Openmediavault boot drive
- 1x Noctua NF-A14 for cooling heat sink and NVMe
- 1x 1Gbit LAN connected
No monitor, keyboard or other devices connected!
The whole system draws 3.8 - 5.5 Watt from the wall. 24h consumption is 0.072kWh!
Minfred regarding the Asrock N100DC-ITX have a look at the following video:
Perhaps this will help you with your decision.
To remotely shutdown the attached devices you can do it via SSH using
ssh user@host1 poweroff
ssh user@host2 poweroff
ssh user@host3 poweroff
...
Below follows the essential collection of Docker containers I have in use:
- Wiki.js for documentation purpose
- Gitea for hosting my Git repos
- Paperless-ngx because I hate paper based documents
- Syncthing, for syncing selected data of mobile devices
- Unifi Network Application, controller for my Ubiquiti gear (switches & access points)
- Homer, a homelab dashboard
- PostgreSQL, for various DBs needed by some of the other Docker Containers
If I access FTP via external access on my home network, it works. If I try it outside of my network or on mobile data it fails.
So if everything works while you are connecting from your local network (LAN), but not when you are trying to connect from outside (WAN), it sounds like you don't have port forwarding configured on the router.
Krisbee the pools I've created on my OMV host via CLI using:
zpool create -o ashift=12 virt mirror /dev/nvme0n1 /dev/nvme1n1Verification:
zdb | grep ashift
ashift: 12zfs get sync virt/docker
NAME PROPERTY VALUE SOURCE
virt/docker sync standard defaultAs you're using latest zfs 2.2.2 version, which is meant to improve overlay2 performance, I wonder if you've tested this before using the zfs storage driver ( see: https://github.com/openzfs/zfs/issues/15581 )
No, I did not run such tests.
I'm thinking about to start using the Openmediavault Compose-plugin.
After weighing up the pros and cons and the benefits of the proposed workflow change, I decided to keep my current one.
Working in the CLI feels far too comfortable.
Right now I'm managing all my Docker containers using a dedicated user (docker) via docker-compose.yml files within a SSH session.
On one of my ZFS pools I've created the following file systems/shared folders:
- appdata, which houses, within subdirectories, compose files & container specific data
- docker, former location: /var/lib/docker
- backup, backups of appdata
To allow proper usage of ZFS and to promote the new location of the Docker data directory I'm using the following custom daemon.json file:
{
"storage-driver": "zfs",
"data-root": "/mnt/virt/docker"
}- Reuse above mentioned directory structure
- Keep my custom daemon.json, realized by an empty Docker storage line within settings dialog of the Compose-plugin if I understood it right
- Reuse my current docker-compose.yml files
- move settings of various container base env-files to a single one and update docker-compose.yml accordingly
Will this be as simple as installing the plugin, configure it (the shared folder paths) and regenerate my docker-compose.yml files within the OMV GUI?
And the best is: TIL what the Tag input boxes are useful for 
.
Tested and also works like a charm 😀 Thanks matdb 💯. Seems to be the better solution because its more the OMV way I think.
If you set something in the "tag" field of the cron job in the OMV webgui it gets part of the mail subject
I will try this out later today and report back. Think this will also work in OMV7.
