I would create virtual disks on the ceph hdd pool for the VM. I've never used ceph on proxmox though.
and how these virtual disks should be mounted on OMV? by using the remotemount plugin?

IF we assume
Depends on what you mean. If the VM is presented with virtual storage that look like virtual disks to the VM, then it will work fine. If you are thinking of installing the ceph client on the VM, then no.
Thank you for your reply.
Lets assume that the VM is installed successfully. On the cluster, I will have two pools. One pool consisting of NVMe drives for the VM, one pool consisting of HDDs for storage
Through docker, I would like to install navidrome in order to stream my music through internet and a samba share that will enable streaming my music to other devices inside my home.
The samba share would be a folder created through OMV (which is a VM). I will have to somehow pass the HDD pool into the VM. How it would be best to do this? Through cephfs or is there another/better way to do it?

I want to bult a 3-node proxmox cluster, add ceph and cephfs on it.
The cluster will run a VM of OMV and will be basically my working place, since i am planning to move my current bare metal omv server to my parents house.
The omv as a VM will be a file server for sharing files, a music server where all my music will be stored and distributed/streamed to all my devices in the house as well as the place for all my self-hosted services.
Will OMV work on cephfs? has anyone tried this?

As the title implies, I am receiving a strange message after a power outage I had last night.
The message can be seen in the attached photo.
Any ideas as to how to fix this?
Thank you all for your contribution

Hello everybody,
I am thinking of moving my existing “bare metal” installation of OMV to ProxMox.
As of today, I kept my my docker configuration folder and associated data on a separate drive than my OS drive, because with this setup it was easier for me to backup those two drives separately and also gave me redundancy in case one drive goes down.
Now that I will move to ProxMox and setup a HA cluster, I was thinking to have my docker configuration folder on the same drive as my OS drive, because it will be easier to backup the VM containing essentially my entire configuration AND with live migration I will have zero downtime in case something happens with the cluster.
Do you think the above a good idea or should I retain my existing practice to PoxMox as well??

Good day to all,
Today when i updated (together with new containerd and docker version) from 6.3.4-1 to 6.3.6-2 i received the following errors in the log, highlighted in bold letters.

END OF LINE
1) I have not touched the Configuration file '/etc/default/openmediavault file. how could this be altered?
2) What does this "[ERROR ] Exception during resolving address" means and how it can be fixed?
3) What does this "[Errno 2] Host name lookup failure" means and how it can be fixed?
Thank you for your time

Much fuzz is in the air the last days regarding the recent decisions from the docker team.
What to know about the end of Docker Free Teams | DockerWe apologize for how we communicated and executed sunsetting Docker “Free Team” subscriptions, which alarmed the open source community. Read our FAQ to learn…www.docker.comHow will this affect OMV? Will a decision be made to move to another service, like podman?
Can anyone please explain in simple words how this change will affect us, the plain users?
Thank you for your time in explaining all this.

Have a look here for an explanation on RAM and SWAP, and when it's health or not.
If you have a container running that perhaps has a memory leak causing the RAM usage to continue to grow, you could potentially implement a docker RAM limit on the container or schedule a periodic restart of the container to release the RAM.
Thank you
-
That didn't help since all of the columns are in one field. I just wanted to add up the memory use. Looks like is a little over 7GB.
All I can guess is your memory use goes way up when actively using the containers.
your guess is correct, because from the 32GB of RAM usage, currently only 8GB are free. The rest is consumed by the containers. However, this does not explain the high swap usage, unless what BernH claims is correct, a statement i cannot verify because my knowledge in linux is limited.
-
Any chance you could post that in a format that doesn't break the formatting? Like a spreadsheet or csv? That is a lot of containers. Photoprism and its database alone are using 2.5GB of ram. I'm guessing things like paperless, onlyoffice, and duplicati use more when they are actually being used as well. What are you doing with the system other than docker?
Here is the link in csv format, since the extension is onvalid by the uploader: https://fileshare.fsnaval.com/share/dockerstats
Other than docker and acting as a NAS server for file sharing and movies streaming (rarely), no other uses.
-
Adding swap is not the right way to go. If your system is swapping that bad, you should add more ram. Post the output of docker stats.
Please find attached requested info.

Good day to all,
I have noticed that my system is systematically using all its swap memory. Is there a way i can increase it and how should i do it?
I am running a lot of containers and maybe this is the cause of the high swap usage. I have 32GB of memory and 1TB nvme for OS, of which i hardly use 20%.
Thank you!

OMV uses PHP v.7
Update without fear.
Thank you!
-
Good day to all,
today i received an update mail from my server, informing me that there are updates for the php7.4.
I am running OMV6 so, unless i am mistaken, the php version should be 8? Am i missing something? Should i proceed with the update?
-
I don't think that's a wise approach. It's like refusing to get your oil changed because you're worried about a check engine line.
The fix for this is literally less than 10sec.
You do have a point here, nevertheless i will wait a couple of days more to see if anything new comes up before i proceed with the docker upgrade.
-
I have also received the notification to upgrade the docker to the new version but after reading here, i will not do so. Is there a way we can choose to skip and/or ignore these docker upgrades from the update management menu, until another docker version comes up without having these issues?
-
The shared folder is where the backup will go.
The root folder should not need to be set. Hence the note.
Thank you for your reply. Can you tell me how will i restore the created image if i need it?
-
Good day all,
I want to setup a backup job of my OS drive using the backup plugin, in particular the dd full disk option.
However, i am not sure how to set it up correctly.
In the attached images, i understand that the following fields should be filled in like below:
Shared folder: None
Method: dd full disk
Root device: /dev/nvme0n1 (this is my OS drive)
Keep: 2
Is my understanding correct?
However, i do not see where i should point the backup destination, as i want to backup on an external drive. What am i missing?
Thank you all for your assistance.

These seem to be results of different drives.
Maybe these instances occurred in different time intervals?
