Re: [ceph-users] Using CephFS in LXD containers

If rbds work for your use case, I would recommend them. Networked posix filesystems are a last resort, imo. Generally you use them when proprietary software will not work with an rbd or object store (without having to run nfs or something else on top of an rbd). On Wed, Dec 13, 2017, 4:22 AM Bogda

Thanks a lot for the info, David! Have you encountered any file sync issues while using CephFS from the containers? How is the overall performance? have you also used RBD images? if yes - how is the CephFS performance, compared to the RBD performance? Thank you, Bogdan On Tue, Dec 12, 2017 at 7:

We have a project using cephfs (ceph-fuse) in kubernetes containers. For us the throughput was limited by the mount point and not the cluster. Having a single mount point for each container would cap with the throughput of a single mount point. We ended up mounting cephfs inside of the containers

[ceph-users] Using CephFS in LXD containers

2017-12-12 Thread Bogdan SOLGA
Hello, everyone! We have recently started to use CephFS (Jewel, v12.2.1) from a few LXD containers. We have mounted it on the host servers and then exposed it in the LXD containers. Do you have any recommendations (dos and don'ts) on this way of using CephFS? Thank you, in advance! Kind regards
