Re: [ceph-users] Multiple cephfs filesystems per cluster

Thanks John - It did look like it was heading in that direction! I did wonder if a 'fs map' & 'fs unmap' would be useful too; filesystem backups, migrations between clusters & async DR could be facilitated by moving underlying pool objects around between clusters. Dave On Wed, Sep 17, 2014 at 1

Hi David, We haven't written any code for the multiple filesystems feature so far, but the new "fs new"/"fs rm"/"fs ls" management commands were designed with this in mind -- currently only supporting one filesystem, but to allow slotting in the multiple filesystems feature without too much disrup

Hi Cephalopods, Browsing the list archives, I know this has come up before, but I thought I'd check in for an update. I'm in an environment where it would be useful to run a file system per department in a single cluster (or at a pinch enforcing some client / fs tree security). Has there been muc

Hi, Is it possible to have more than one CephFS filesystem per Ceph cluster? In the default configuration, a ceph cluster has got only one filesystem, and you can mount that or nothing. Is it possible somehow to have several distinct filesystems per cluster, preferably with access controls that
