So I've followed a whole bunch of issues here for a good few hours and I wouldn't ask here if I wasn't completely out of ideas.
So today I came home to find my rpi3 unresponsive. It's running Stretch, with Kodi and a couple of hardrives as a media system. Only thing I could do was unplug it. When I did, I got the "Kernel panic-not syncing: VFS: unable to mount root fs on unknown- block(179,2)" error that is seemingly well documented. It's a relatively new install.
I go through the troubleshooting and attempt to go to recovery mode, but shift is not recognised. So I go to the next step which is to alter cmdline.txt. However, on my macbook it appears /boot is not writeable and nothing I do will make it so. So I;
- Install osxfuse so I can see the other partitions (tho this is not actually needed), but it does show the partition is intact in diskutil
- Attempt to remount the sd card as writeable, but still get permission denied.
- Try another micro sd card in the adaptor to make sure it's not the sensor in my sd card reader that is not recognising the write protection being off. Other sd card writes fine
At this point I'm completely done. As soon as I can edit this cmdline.txt I can continue to troubleshoot but I just cannot mount this as writeable. Any ideas?
