Re: mount.ceph Cannot allocate memory

So you're doing all of these operations on the same server? We don't recommend using the kernel client on the same server as an OSD, but that is unlikely to be causing your issue here. Still, ENOMEM is most likely happening in your kernel, and probably indicates that for some reason it genuinely can't allocate some memory. Have you checked dmesg to see if it has any useful information?

CephFS isn't going to work if you don't have a metadata server running...
