Hi, and my system disk is completely full after I wanted to run a Snapraid Sync and got an error message "Probably the paerity file is missing".
Unfortunately, I'm still a noob in terms of Linux, I would be glad if you could help me, as I get the system disk cleaned up again without having to reinstall everything again.
OMV4 system drive overflowed after a failed Snapraid sync

First you need to find out, where the files have been synced to.
What is the output of
du -x -h -d1 /?
This will show your the size of every folder in root (without descending on other filesystems)

Ok, /srv is quite big. /srv is where the other drives are mounte, but as we are not descending in other filesystems there must be something else.
So let's see what there is:
du -x -h -d1 /srv

That seems to be the issue, but I am not sure if it is safe to delete the directory. I am not using snapraid.

Let's see if somebody else has an idea.
TBH I didn't answer because the request looked confusing and even after the above it still does. @flmaxey uses SnapRaid and I am in the process of moving to it using UnionFS.
The confusing part here is the thread title, SnapRaid should have nothing to do with the drive OMV is installed on.
But my understanding is this; say you have 4 drives you are going to use, 3 drives are for data and 1 which much be greater or the same size as the others. So if you have 4 x 2TB drives 3 are used for data and 1 is used for parity.
I did however find this but I'm not sure if that will help....but the message "Probably the parity file is missing" could imply that this has not been set up correctly, but it could also mean that SnapRaid is confused because there are 2!!
Another option would be to inspect the content of the parity by cd /srv/dev-disk-by-label-Paritaet1 then doing ls -l that will at least list the files on that drive.
Perhaps another option might be to have the output of blkid.
But going back to that link it could also mean to check the snapraid.conf and config file, but not sure what the later is.

Hi, there are a total of 6 hard drives installed. Sda1 is system disk OMV. 4 more are data disks and 1 paerity hard disk. Snapraid was set up properly and ran for half a year without any problems. But then I wanted to sync again and there was an error message and suddenly the system disk was full

Ok so that's not the problem, looking at du -x -h -d1 /srv your output was;
236G /srv/dev-disk-by-label-Paritaet1 this is wrong, wrong in the sense of the size and wrong in that it's a directory but I don't know why or how, unless there is some sort of corruption of the parity drive itself, hence the creation of that directory.
8,0K /srv/ftp
236G /srvThis is the output from my own machine using the above;
8.0K /srv/ftp
12K /srvSomething within the SnapRaid config has created that, but why and how? Have you looked at the file/s within that directory? cd /srv/dev-disk-by-label-Pariteat1 then ls -l.
-
One possibility is that the SnapRAID parity drive didn't get mounted and when the sync was run, the parity file was newly created, but in the directory where the mount was supposed to happen. This could have caused the rootfs to fill up because /srv is on the rootfs.
Look for a .parity file there - in the mount point directory with the parity drive not mounted.
