I'm hoping I understand the -C (--complete-only) option properly.
I have a rescue that I am doing that I wish to limit to the current
amount rescued, just filling in the areas that didn't rescue the first time.
Initial run as
$ ddrescue /dev/sdc /dev/null rescue.log
....
Current status
rescued: 211755 MB, errsize: 108 kB, current rate: 72744 kB/s
ipos: 211755 MB, errors: 2, average rate: 69519 kB/s
opos: 211755 MB, time from last successful read: 0 s
^Cpying non-tried blocks...
Interrupted by user
I then add the -C option so that I can force it to rescue the parts from
the 2 errors.
$ ddrescue -C /dev/sdc /dev/null rescue.log
Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 211755 MB, errsize: 108 kB, errors: 2
Current status
rescued: 212003 MB, errsize: 108 kB, current rate: 73662 kB/s
ipos: 212003 MB, errors: 2, average rate: 61980 kB/s
opos: 212003 MB, time from last successful read: 0 s
It just continues rescuing from the end of the logfile instead of
limiting it to the log file blocks.
Thinking it may be because I'm using /dev/null as the output, I also
changed it over to a file (which of course at this stage only used a few
Mb instead of many Gb due to the holes in the file as it had already
rescued the rest to /dev/null).
I expect the -C option to prevent it reading past the data already
rescued (so 212003 MB now) and work at rescuing the remaining data
between 0Mb and 212003 MB.
