Like some problem for ddrescue to write out the mapfile completely/correctly.
The free space on the drive holding the mapfile was only ~44 kB (copying 1
TB *disk device* to 1 TB *file system*, you know ...), the mapfile itself
was ~134 kB.
But there was no "Error writing mapfile 'mapfile': No space left on device"
Thank you for reporting this.
I have no idea what can be the cause of the problem that you describe (a
hole in the middle of the mapfile). Ddrescue writes the mapfile calling
'fprintf' in a loop, once per line, and checks the return value of 'fclose'.
All I can do is making ddrescue also check the return value of each
'fprintf' in case the problem is a temporary failure of 'fprintf' that is
not signaled at closing time.
Best regards,
Antonio.
