root partition is read-only

Hello,

I think i made a big failure.

I installed and configured OMV on a SSD, all runs fine until I installed the flash-plugin to safe my ssd.
After i configured /etc/fstab. and reboot my system nothing seems to be run.

if I try to edit my fstab it says me, that my system is read-only.

also a

root@omv:~# omv-mkconf fstab
sed: Kann temporäre Datei /etc/sedFuM8pa nicht öffnen: Das Dateisystem ist nur lesbar<-- read only, sry for german text.

Has somebody an Idea?

ok, thx, this work, I have reset the changes i made and remove the openmediavault-flashplugin.

VDR is working again, but the webgui and still not work.
