Home Directory is ReadOnly (NotWritable)

This is a clear warning that the device has massive problems!
The last time I ignored such warning signs, it cost me more than 100€ for data recovery. It was still a spinning disk though. Since then I’ve been healed!

Since you are the admin:

Don’t repair, replace !

Most other file systems would only have reported this when data had already been lost! Because BTRFS writes (and checks) checksums, it notices the error IMMEDIATELY.

:warning: BTRFS will not allow you to write more data to a defective drive !

All data written before the message is normally intact (eventually do a btrfs scrub from within a live manjaro). But if the drive finally fails, there is no rescue other than the professionals (which costs a lot of money)

:footprints:

P.S.:
  • You will be able to mount the filesystem readonly for recovery (with rsync)

  • Or you could clone it with btrfs send/receive

  • Do recover your data using a live manjaro (iso/usb). Not with your broken system !
