Hi,
My data2 and data3 drives have more free space than the other data drive.
My UFS current option is : Existing Path, Most Free Space.
Any idea ?

EPMFS will use the existing path FIRST. Paths will be preserved if possible.
And only then, if the same relative path happen to exist on more than one filesystem, the filesystem with the most free space (MFS) will be used.
So if a folder didn't exist on any drive, it is added to the drive with the most free space. After that the path exists on one drive only and all subsequent files in that folder end up there.
If you want files to be added to the filesystem with the most free space, and paths created as needed, then you should use just MFS, not EPMFS. That will spread the files all over your drives.
If the disk is full, will it use the other disk ?
If I change from EPMFS to MFS, would my data be lost ?
Yes. I think so. I haven't tried it yet.
No. Not if you have good verified backups.
But if you don't have good verified backups then all your files will be toast. Any change you make is almost guaranteed to cause catastrophic data loss. I almost promise 100%!
What about using the mergerfs.balance script to even the spread of data across the drives?
When I started with UFS/Snapraid I noticed uneven spread and this script ran for a few hours and evened disk usage up. Since then the disk use has been pretty even. My setup is MFS. This was on OMV v4.
Naturally I had backups before I did this.

I did some back up.
My concern is whether the existing path will still work after change it to MFS option.
I assume that new files will cause the same folders to be created on more drives, as new files are added and spread. The existing folders and files should remain where they are, unless you run the mergerfs.balance script.
Changing from epmfs to mfs should be no different from creating a new mfs mergerfs pool from existing filesystems.
Be sure to let us know how it works. I have not a lot of experience with mergerfs, but see a lot of potential in it.
The thread subject should be changed because SnapRAID has nothing to do with it.

Done.
I notice that since I'm starting using SnapRaid/MergerFS, my server can't enter hibernation mode.
Anybody else has this issue ?

Are you referring to the WOL plugin? Do you have a media server running, Plex, Emby, Jellyfin etc.
I find it annoying that you didn't start a new thread for a different problem.
What's your problem, man ?
This is my thread.
If you don't like it, start your own thread !
