Is it safe to use the discard mount option when mounting a xfs filesystem on an rbd (using the kernel driver)? We're currently using kernel 3.5.3 and Ceph 0.48.1. Also, are there any stability issues doing it from a qemu VM? It looks like support for rbd discard was added in qemu 1.1, but I wasn't sure how stable it was. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
