Hey folks!

I've got a server on OMV5 that I will use for the following activity:

serve media to clients at home

serve media to clients outside the network (seldom)

serve files to clients in and outside the home

downloading and sorting initiated by automated recurring requests from docker containers software and ad hoc requests from web uis of said docker container software

snapraid sync/scrub/fix jobs

What's the best way to set up power management and WOL so that I'm using as little power as possible?

Thanks!

Hi there! I want to get Jellyfin (or Emby or plex or whatever, though jellyfin is my preference) to use my video card for transcoding. The media server will be running in a Docker container, and I think I can user nvidia-docker ( https://github.com/NVIDIA/nvidia-docker ) to get the job done. But for now, I can't even install the NVIDIA drivers, which seems to be a prerequisite. Following the guides I can find online, the package installation keeps failing, and running NVIDIA-smi says that no drivers are running. Halp, please!

Long story short, I need to remove a disk from my UnionFS pool and instead use it as a parity drive. I'll be replacing it with a different, smaller drive. I have a "most free space" policy, so my data is pretty evenly distributed among the existing pool.

Depending on what policy you use in mergerfs new files are not accepted, are stored on one drive until it is full, or spread out on all drives. It is all in the docs. Existing path, most/least free space and so on.

I think it is called create policy, not storage policy.

Further update! I notice that now, in light of the "most free space" policy (with no "existing path"), the files are getting moved around the various disks in order to find the right level. While this is going on, I can't seem to add any more files from the external USB drive ("Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; umount -v '/srv/84b7f8555478cb6519636c9623872717' 2>&1' with exit code '32': umount: /srv/84b7f8555478cb6519636c9623872717: target is busy."). Does this mean that I will run into problems adding new content while this drive balancing is occurring in the future?

So, I have it on “most free space,” but it looks like the USB backup plugin is just dumping everything on one drive...

UPDATE: Figured this out, it's because the policy was on "existing path."

When you set up the rsync job you specify to preserve owner, group and permissions.

Or you can add the --chown argument to the extra options to change owner and group.

I am not aware how to inherit owner, group and permissions from the upstream folder.

But you can reset permissions by using the resetperms plugin

Ah, interesting. I didn't realize that it would keep the old owner. Those are gonna be completely different from what OMV operates on now...But using resetperms makes sense, too.

Quote from macom

You should move the data as the user that shall have access rights to these data. You can check this with a few files first, to see if everything is working.

So don't run rsync as root?

Quote from macom

Regarding folder granularity, I think this is a matter of preference. However, you should avoid to have everything in one folder

/Server/data/myname/

unless there will be also folders on the same level as data or myname.

If you have

/Server/data

/Server/movies

...

it is easier for backup, as you only need to backup /Server/

If you have

/data

/movies

....

it can be easier when navigating to these folders e.g when setting up docker.

To be clear, I see there being a difference between the shared folders explicitly defined within OMV (which will only be "Server") and the actual folder structure, as imported from the old HDD, which will be "Server\Movies," "Server\Music," etc.

Quote from Adoby

You will only have one top-level shared "server" folder.

But in that folder you will have all normal sub-folders that were on the HDD you copied. And these sub-folders, along with their contents, will be shared as part of the main shared "server" folder.

Unless you have some specific access/security requirements, I think it is better and easier to manage few (one?) shares with many sub-folders than a lot of separate shared folders with few sub-folders.

Make sure you have the right storage policy set in mergerfs.

Thanks! Yeah, I think I will just have one folder, "Server," with the rest being subfolders that are not explicitly defined in the Shares menu in OMV. Make sense?

By the "right storage policy," what do you mean?

Quote from macom

As I understand you have currently one shared folder which is called "Server". If you now copy the data from the old drive in this folder, you will still have only one shared folder. But you can create additions shared folders in the GUI of OMV and point them to existing sub-folders in "Server".

In the picture you can see, how to select an existing folder when creating a new shared folder.

Thanks for your response! Let me try to be a little more clear. I will be moving the entire folder structure into this one shared folder. Will doing make all of the subfolders (which have been moved from the USB drive into this shared folder) inherit the "Server" folder permissions?

In other words, I have one folder on OMV: "Server"

Into "Server," I am moving the contents of /dev/sdx, which has a structure of, e.g., "/data/myname/subfolder/subfolder/subfolder" and "/Music/Artist[1]-[n]/Album[1]-[n]." I assume that all of the moved folders will also be shared? Is there any reason I should be a little more granular and create "data," "music," "movies," and "TV" folders before moving those individual folders over?

hi there! I have a bunch of files (10TB) on an external HDD pulled from an old server, arranged into a particular folder structure. On my new OMV drive, I've set up my data drives pool as a single shared folders called "Server" (through MergerFS). If I use rsync to copy the entire HDD (with folder structure) into "Server," will the new folders show up as folders and be available for sharing within the OMV GUI? Or is it a better ID to create a folder structure within OMV first and move the contents of each folder over one at a time?

Thanks!

Hey folks!

I installed a cheapo SATA expansion with a Marvell controller. I can confirm that I can access the controller BIOS and have left the drives "Unconfigured" (I don't want to enable RAID). I don't see the drives in OMV, so I assume I need to enable backports. How do I do that? I've installed OMV-extras and hit the "backports" toggle, but can't see what the next step is. Thanks!
