Hello, Due to lot of reports of ENOSPC for xfs-based stores may be it worth to introduce an option to, say, ceph-deploy which will pass allocsize= param to the mount effectively disabling Dynamic Preallocation? Of course not every case really worth it because of related performance impact. If there is any method to calculate 'real' allocation on such volumes, it can be put to the docs as a measurement suggestion too. -- 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
