Two new btier releases have become available.
btier-1.3.10 is hopefully a final bug fix release.
It should be stable and ends btier-1.3.x series development.
Btier-1.3 will still be maintained should bug fixes be necessary.
All the new development will take place on 2.0. This release will be different in a number of ways.
Btier-2.0 will not support VFS / using files as backend store.
It will only support recent kernels. Any time ifdefs should be required to make it work with an older kernel the support for that older kernel will be dropped.
The design of btier-2.0 is cleaner and allowed much better performance.
This can easily be illustrated with the help of two RAM drives and putting either btier-1.3 or btier-2.0 on top.
Btier-2.0 seems to be stable. However this release will undergo some overhauls in the time to come. So 1.3.10 should be the current choice for production.
Enjoy,

Hello
I ‘m setting up a PACS DCM4CHEE on CentOS .
To manage different tiers of storage (online , intermediate, archived ) I fail to operate a hierarchical system .
I have been studying the btier , and I think it can be a great solution , the only doubt is the limitation of 16 discs .
In future iterations of btier such limitation shall be increased ? In the PACS many more discs may be required to store the studies.
Thank You.
Greetings .
The limit of 16 devices is a soft limit. It can be raised without problems.
Thanks!
