v0.9.0
|
|
======
|
|
|
|
- New support tools: thin_metadata_{pack,unpack}.
|
|
- thin_check can now check metadata snapshots.
|
|
- some metadata space map bug fixes.
|
|
- thin_check --auto-repair
|
|
- Stop thin_dump --repair/thin_repair ignoring under populated nodes.
|
|
|
|
|
|
v0.7.5
|
|
======
|
|
|
|
- Fix a bug that stopped cache_restore working with metadata version 2.
|
|
|
|
v0.7.4
|
|
======
|
|
|
|
- Update this file ;)
|
|
|
|
v0.7.3
|
|
======
|
|
|
|
- Improve error messages if XML given as input to tools that expect metadata.
|
|
There seems to be some confusion between XML and the metadata.
|
|
|
|
- Add --override-mapping-root debug option to thin_dump. This can be useful
|
|
when investigating damaged metadata.
|
|
|
|
- More functional tests.
|
|
|
|
v0.7.2
|
|
======
|
|
|
|
- Fix segfault in restore tools when given a tiny metadata file (< 4k).
|
|
|
|
- Lots more work on the functional tests.
|
|
|
|
- Fix a couple of unit test regressions
|
|
|
|
- Man page updates.
|
|
|
|
- Rewrite man pages in a text format. Simpler than writing directly in nroff.

v0.7.1
|
|
======
|
|
|
|
- Fix a few bugs in block_cache.
|
|
|
|
- Ditch Ruby/Cucumber for the functional tests. Now written in Scheme.
|
|
|
|
- Be more aggressive about flushing dirty blocks from the block cache. Very
|
|
little performance impact.
|
|
|
|
- Optimisations in space_map_disk (small performance improvement for restore
|
|
tools).
|
|
|
|
v0.7.0
|
|
======
|
|
|
|
- switch to C++11. This may cause problems with v. old versions of g++.
|
|
|
|
- support cache metadata format 2
|
|
|
|
- support custom emitter plugins for thin_dump.
|
|
|
|
- thin_dump --dev-id; allows the user to dump just the devices they're
|
|
interested in.
|
|
|
|
- cache_writeback; Use for offline decommission of a cache.
|
|
|
|
- thin_scan/thin_ll_dump/restore dev tools.
|
|
|
|
- --enable-dev-tools configure option. Use this for the extra tools.
|
|
|
|
- thin_delta, various bug fixes.
|
|
|
|
- various changes to the block cache.
|
|
|
|
- thin_show_duplicates; a development only tool that scans block devices to
|
|
calculate the level of data duplication. Uses either fixed block sizes or
|
|
context sensitive.
|
|
|
|

|
v0.6.1
|
|
======
|
|
|
|
Fix bug in thin_dump when using metadata snaps.
|
|
|
|
v0.6.0
|
|
======
|
|
|
|
thin_ls
|
|
|
|
v0.5.6
|
|
======
|
|
|

era_invalidate may be run on live metadata if the --metadata-snap option is given.
|
|
|
|
v0.5.5
|
|

You may now give the --metadata_snap option to thin_delta without specifying where the snap is.

Update man pages to make it clearer that most tools shouldn't be run on live metadata.
|
|
|
|
Fix some bugs in the metadata reference counting for thin_check.
|
|
|
|
v0.5.1
|
|
======
|
|
|
|
Fix bug where the tools would crash if given a very large metadata
|
|
device to restore to.
|
|
|
|
v0.5
|
|
====
|
|
|
|
- thin_delta, thin_trim
|
|
- --clear-needs-check flag for cache_check
|
|
- space map checking for thin check
|
|
|
|
v0.4
|
|
====
|
|
|
|
- All tools switch to using libaio. This gives a large performance
|
|
boost, especially to the write focused tools like thin_restore.
|
|
|
|
- Added a progress monitor to thin_restore, cache_restore and era_restore
|
|
|
|
- Added a --quiet/-q option to *_restore to turn off the progress bar
|
|
|
|
- Removed variable hint size support from cache tools. The kernel
|
|
still only supports a fixed 32bit width. This will have a side
|
|
effect of reducing the executable sizes due to less template
|
|
instatiation.
|
|
|
|
- Tools rolled into a single executable to save space.
|
|
|
|
- Fixed some bugs when walking bitsets (possibly effecting cache_dump
|
|
and cache_check).
