I'm pretty sure this is the 'rw' mount option bug that Josh just fixed. It affects kernels older than 3.7 or so and Ceoh newer than .70 or .71 (somewhere in there). Can you try installing the package for the 'next' branch from gitbuilder.ceph.com? If you are using ceph-deploy you can do
ceph-deploy install --dev=next HOST Thanks! sage nicolasc <nicolas.cance...@surfsara.nl> wrote: >Hi Greg, > >I apologize for the lack of details.
