SnapRAID HISTORY
|
|
================
|
|
|
|
1.1 2011/5
|
|
==========
|
|
* Fixed a bug in the check command when detecting garbage data over the
|
|
expected end of the file. No special action is required to update.
|
|
* Changed the default checksum to Murmur3 hash. It's a lot faster than MD5.
|
|
You can check its speed with the "snapraid -T" command.
|
|
MD5 is still supported for backward compatibility.
|
|
To convert to the new Murmur3 hash, simply remove the 'content' file,
|
|
and start a new whole 'sync'.
|
|
* Added RAID6 support. It's used the very good RAID6 library made by H. Peter Anvin
|
|
also used in the Linux Kernel. It contains optimized implementations for SSE2
|
|
and MMX.
|
|
* Added support for multiple 'content' files. You can save extra copy to be able
|
|
to verify the checksums also if you lose all the 'content' files in the parity
|
|
drives.
|
|
* Added a filtering include logic, where anything not explicitely included
|
|
is excluded. For example, it allow to include only the files in a predefined
|
|
set of directories.
|
|
* The check command returns with an error code if any kind of error is present.
|
|
Previously it was returning an error only if unrecoverable errors were
|
|
present.
|
|
* Opening the files in sequential mode in Windows. This should give a speedup
|
|
in Windows.
|
|
|
|
1.0 2011/4
|
|
==========
|
|
* No relevant change.
|
|
|
|
0.4 2011/4
|
|
==========
|
|
* Added hidden 'dry' command mainly for speed measurement.
|
|
* As default, uses the OpenSSL crypto MD5 implementation.
|
|
|
|
0.3 2011/4
|
|
==========
|
|
* Added --filter option to select a subset of file in check and fix.
|
|
* Better ETA estimation in all the commands.
|
|
* Added support for OpenSSL crypto library to use its optimized MD5 implementation.
|
|
* Added test vectors and a speed test for MD5.
|
|
|
|
0.2 2011/3
|
|
==========
|
|
* Second public test release of SnapRAID.
|
|
* Functionally complete in check and fix.
|
|
* Files are identified by inode and not anymore by name.
|
|
* Exclusion list of files and directories.
|
|
* Precise error management.
|
|
* More regression tests.
