Easy CentOS 5 install

Easy CentOS 5 install

[Jonathan Tripathy]

Hi Everyone,

What is the easiest way to install bcache on a currently running 
production CentOS 5.x machine? Is there an official and/or EPEL package 
available? We would also need Xen Dom0 support...

Thanks

Jonathan

I built the bcache-tools package for Fedora 20, which has some specific 
requirements (that are met by Fedora 20):

- util-linux >= 2.24, because libblkid (>= 2.24) is able to identify 
bcache devices which greatly improves dracut functionality
- dracut < 34, because bcache-tools includes the dracut module for 
bcache which was part of dracut from dracut-31 to dracut-33

Having your root FS on bcache requires the proper util-linux and dracut 
versions, but when not having your root FS on a bcache(d) device it 
should be possible to use bcache on e.g. CentOS. This requires a 
modification of the current src.rpm though, which I won't mind doing if 
you intend to use it

Please let me know.
