An error occurred opening the output file; it is likely that the output
directory does not exist or is not writable, the output file already exists and
is not writable, or the disk is full.
I test other files in same directory just fine. The disk isn't full and i have write access. The file obvious already exist and i'm using "-f".
flac issue? bash issue? (same filename completion used ) filesystem issue? (using btrfs)

decode to wav and encode the wav to flac works.
but again if i run flac -8f on flac file it don't work.

An error occurred opening the output file; it is likely that the output
directory does not exist or is not writable, the output file already exists and
is not writable, or the disk is full.
Filenames in btrfs cannot be longer than 255 bytes. This filename has a length of 250 bytes. When FLAC re-encodes, it writes to a temporary file, of which the filename is the same but appended with a few characters. This makes the filename longer than 250 bytes.
Specifically: here's the appended stuff:

It looks a little strange, the idea is to make it incredibly unlikely the tempfile already exists in some form.
As a workaround, you could rename the file, re-encode it (to preserve metadata) and then restore the original name.
