I have a ceph testbed running on RHEL 6.2 using kernel.org kernels. I use both stable series kernels, and Linus's master branch (usually after -rc3 or so on each new kernel). Occasionally a new driver version for my hardware wants a new firmware blob, which is easy to get from the kernel.org linux-firmware tree. -- Jim > > > Thanks guys, > Dieter > > PS: links to http://ceph.newdream.net/docs/master/ and > http://ceph.newdream.net/wiki/ from the menu on the homepage would be useful. > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > >
