Objet: [sheepdog] [ANNOUNCE] Sheepdog 0.5.0 released
I'm pleased to announce the availability of the 0.5.0 release.
The software is available from GitHub:
Major features include:
- manual object recovery
We can disable automatic data recovery with
'collie cluster recover disable'. This is useful, for example,
when you reboot a storage node for maintenance and don't want to
run data recovery during the time.
- incremental backups of VDIs
This release adds two commands 'vdi backup' and 'vdi restore' to
collie. With these commands, you can create incremental backup
files between snapshots. It is useful to reduce backup data size.
- testing framework
We add a xfstests-style test suite in this release. With this
framework, we've fixed a lot of bugs and I believe sheepdog becomes
- set virtual node numbers based on free disk spaces
With this feature, even if sheepdog cluster doesn't have the same
sized disks, sheeps can ideally balance objects.
- reimplement farm over plain store driver
The previous implementation of farm has a problem that sheep blocks
I/O long time during object recovery. This fixes it completely and
makes farm implementation much simpler.
- sheepdog disk cache
This is yet another write cache implementation. With this feature,
Sheepdog shows a good performance when the number of nodes is not
big (less than 10 nodes).
