Just an update: that was true for a while, but at one point listing directories
and accessing the file system in general stopped working (all processes that
touched the FS hung/zombified). This necessitated a hard reboot, since "reboot"
and "halt" (so... "shutdown", really) didn't do anything other than spit out the
usual "the system is rebooting" message.

Interestingly enough, the file system was (apparently) fine after that (just as
Petr Janecek wrote), other than an invalid space cache file:

  [   65.477006] BTRFS info (device sdg2): The free space cache file
  (2466854731776) is invalid. skip it

That is, running my backup routine worked just as before, and I can access
files on the FS just fine.

Oh, and apparently the rebalance continued successfully?!

  [  342.540865] BTRFS info (device sdg2): continuing balance
  [  342.599991] BTRFS info (device sdg2): relocating block group 2502355320832
  flags 34 [  342.821608] BTRFS info (device sdg2): found 4 extents
  [  343.056915] BTRFS info (device sdg2): relocating block group 2501818449920
  flags 36 [  437.932405] BTRFS info (device sdg2): found 25086 extents
  [  438.727197] BTRFS info (device sdg2): relocating block group 2501281579008
  flags 36 [  557.319354] BTRFS info (device sdg2): found 83875 extents

  # btrfs balance status /media/MARCEC_BACKUP
  No balance found on '/media/MARCEC_BACKUP'

No SEGFAULT anywhere. All I can say right now is "huh". Although I'll try
starting a "balance -m" again tomorrow, because the continued balance only
took about 3-4 minutes (maybe it .
