Don't know why I didn't get a warning about disk being almost full... It came down to zero free space and I couldn't do anything except force-shutdown it. I booted into Windows, deleted some files from OSX drive, but now on boot there is a progress bar every time and when it reaches the end (in 15 min), the computer shuts down.
I went into the recovery mode and tried to repair the disk, but it says "The Disk Utility cannot repair the drive... backup files and reinstall the OS" -- something like that.
I have a time machine backup but I'm currently not at home - going home in 3 weeks.
Is it "normal" that system gets borked like this because of full disk + force shutdown? Seems too fragile to me. I have Mavericks 10.9.4 on this system.
Is there anything I can do?
