Hi, We've been working with Ceph 0.56 on Ubuntu 12.04 and are able to create, map, and mount ceph block devices via the RBD kernel module. We have a CentOS6.4 box one which we would like to do the same. http://ceph.com/docs/next/install/os-recommendations/ OS recommedations state that we should be at kernel v3.4.20 or better. Does anyone have any recommendations for or against using a CentOS6.4 platform to work with RBD in the kernel? We're assuming we will have to upgrade the kernel in 3.4.20 or better (if possible). Thanks, ~jpr _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
