SnapRaid + mergerfs fails

You could do like this for an easy to grow mergerfs pool that once initially configured needs no changes - just add more disks.

Create a directory in the root of your single data drive named Datenpool. The name is arbitrary, use whatever you want for the directory name.

Define your mergerfs pool like this:

Name: Datenpool

Path: /srv/dev-disk-by-uuid-*/Datenpool

The pool will only include files in the Datenpool directory of each disk, not any other files or directories in the root of the drives.

To add a new disk to the pool in the future, just format the disk and create the Datenpool directory in its root. No need to change the the mergerfs configuration as mergerfs will automatically pick up new drives so long as they have a Datenpool directory in their root.

Good luck.

What you are using for the pool path is not what I suggested. You will have to type that in by hand.

You must type the Path in by hand.

I have two pools I created this way in the past. But for some reason this no longer works.

All I get is a new but broken link in the /srv/mergerfs directory. I have no explanation; perhaps one of the devs can help?

OK, found the problem. Change the typed in path to:

Path: /srv/dev-disk-by*/Datenpool

Works for me. What you are seeing is focussing on quotas. Have you made any changes there?

Before that i made a full-backup from extern ....

I don't know what this means.

You are probably getting close to abandoning this install and starting over.

I suppose you can try restoring your backup. It may tell you if your backup strategy is actually working, or not. But those error files that are loaded with quota problems tell me something else is broken. Did you format your hard drives in OMV or are they imported from an old setup?

I don't use the SnapRAID plugin so I can't help you with that other than to say you must have at least one data drive (other than the OS drive), one parity drive, and you should specify both of these drives for content.

There is no relationship between SnapRAID and mergerfs. They are not dependencies of each other and they do not interoperate with each other. They are two completely different things that have nothing to do with each other. Having said that, naming your SnapRAID Array and your mergerfs Pool with the exact same names shouldn't hurt anything, but it isn't going to help anything either. And doing so may be confusing to you and to others when you ask for help. I suggest not doing this.
