OMD page does not start


Until yesterday everything worked FINE. Since today the following error message comes up when I try to start the OMD page.

Looks like you’re filesystem’s corrupted. And in that case Linux remounts it in read-only mode. Rebooting your PI might work, as it will trigger a filesystem check on boot. If that doesn’t fix it, you can try to put your memory card in a PC with Linux and see if it’s possible to fix the FS from there. If not, you may be able to recover your Check_MK installation from it and start with a new OS installation on your pi.
