Comment (by X512):
It's better to use "checkfs -c" first. checkfs is potentially dangerous
operation. If I understand correctly it traverses node tree and remove
invalid nodes. So if folder will be considered invalid it and its contents
will be deleted (https://xref.plausible.coop/source/xref/haiku/src/add-
ons/kernel/file_systems/bfs/CheckVisitor.cpp#351) and child nodes will be
not traversed. checkfs don't attempts to recover unreferenced nodes and
nodes that "cannot be opened".
"cannot be opened" errors can be caused by problems in disk cache. Reboot
can fix that.
BFS is journaling file system and it do not require repair after
unexpected shutdown (but I heard that freeing blocks is required
sometime). Filesystem errors are caused by kernel, file system drivers
bugs and/or disk hardware failures.
