Objet: [sheepdog] [ANNOUNCE] Sheepdog 0.5.0 released 

Hi all, 

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 
much stable. 

- 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).
