emergency mode

Guys, I'm having problems with ArchLinux on startup. His output is like this, what do I do now? (This uses the OCR recognition of the mobile phone, which may not be very accurate.)

You are in energency node. After logging in, tu'6 system logs,"systenctl reboot" to reboot, or to continue bootup.

Re: emergency mode

What is triggering the system using emergency mode?  That would be earlier in the output.  Typically it would be a failed unit such as a failed mount or service.  Can you use the emergency console for diagnostics?

Re: emergency mode

btrfs: Bad value for 'space cache'.

What value is set for space cache for /home in the /etc/fstab and shown in /proc/cmdline?

Re: emergency mode

space_cache=u257

Is that the actual value or the result of OCR?

Re: emergency mode

v257 is not mentioned in btrfs.5.en#space_cache.  I suggest setting it to a documented value.

Re: emergency mode

I changed it to clear_cache,space_cache=v1 and it entered the system normally after . Thank you so much!
