If you have adjusted these settings, please update your ``ceph.conf'' accordingly. + +- New pools now have the HASHPSPOOL flag set by default to provide + better distribution over OSDs. Support for this feature was + introduced in v0.59 and Linux kernel version v3.9. If you wish to + access the cluster from an older kernel, set the 'osd pool default + flag hashpspool = false' option in your ceph.conf prior to creating + the cluster or creating new pools. Note that the presense of any + pool in the cluster with the flag enabled will make the OSD require + support from all clients.
