Boosts the speed of the 'sync' and 'scrub' commands with a new
multi-thread implementation. It uses one thread for each disk,
dedicated exclusively to read-ahead data and parity and to
write-behind parity. This maximizes the data throughput keeping
disks always busy.
You can control the number of blocks to cache with the option
--test-io-cache=NUMBER, where the number is between 3 and 128.
The default is 8 MiB of blocks.
You can show run-time stats during the process with the
--test-io-stats option. You will see a graph with the number of
cached blocks, and a graph with the wait time percentage for all the
disks and computations.
The -h, --pre-hash command, saves the content file only after having
verified all the hashes. This allows recovering of moved files in
case a silent error is found during the hash verification check.
Allows to use the -d, --filter-disk option in the 'up' and 'down'
commands.
Allows to run the 'smart' command without a configuration file.
In such case it operates on all the disks of the machine.
In the configuration file 'data' is now a synonymous of 'disk'.
Adds the 'touch' command intended to arbitrarily set all the zero
sub-second timestamps. This improves the SnapRAID capabilities to
identify files. The 'status' command recommends to run 'touch' if
required.
Restores the functionality of the -D, --force-device option when used
to workaround the use of the same disk for two logical data drives
when running the 'fix' command.
Uses a correct shell quoting in the example commands that involve
files.
The minimum Windows version supported is now Windows Vista. This is
required to use the native Windows thread support for the new
multi-thread implementation. If you need to run on Windows XP, you
have to stick on SnapRAID 9.x.
