Good Morning from Germany,
since working on it to make the external Backup run i have some serious problems and still no solution for it.
It seems that i´m not the only one who ever had the same problem like this how to remove devices in filesystems
I had Problems formating the external HDD (now done, ext4, 4 TB). With this i also deleted on of my NAS Drives (2 x 4TB in Mirror) that was my fault !!! thank God, the Mirror was working and i had at least acccess to my Data, so i could backup them to the external HDD. I formated the deleted NAS HDD (ext4) and tried to run the Rebuild using the WebGUI, this didn´t work (don´t know why) so i tried it again using mdadm this worked.. at least until the next reboot of the hole system. With all this the system created the first wrong Filesystem entry. after the restart i could see my still working Mirror drive and a new drive (the other new formated Mirror drive). I tried to rebuild again with mdadm this worked.. until the next reboot. I started to read the forum and found the above Thread. So i modified the fstab and config.xml (reboot the system) and now i have to missing drives in the filesystem and i´m still not able to delete this both entrys. I also can see my still working Drive and the other one (didn´t not try to rebuild again) I can not see / find any wrong entry anymore within the fstab and config.xml.
i would like to delete this two wrong entrys and make the Mirror run again.
Someone any idea ???
