Configuring a Ceph FUSE client¶
While most clients will use the native kernel ceph client, there may be times where you want to use the FUSE client for rate limiting or if requested by the Jetstream2 team.
You will need the
ceph-fuse rpm if not already installed. You can install it with:
dnf install ceph-fuse
for Redhat-Based OSes like Rocky and Alma. For Ubuntu, you can install it with:
apt-get install ceph-fuse
To mount the manila share created previously you need to edit the three files listed below :
[global] admin socket = /var/run/ceph/$cluster-$name-$pid.asok client reconnect stale = true debug client = 0/2 fuse big writes = true mon host = 220.127.116.11:6789,18.104.22.168:6789,22.214.171.124:6789,126.96.36.199:6789,149 .165.158.86:6789
where the mon host information is provided to you as part of the manila share.
Add the following:
none /mnt/ceph fuse.ceph ceph.id=$accessTo,ceph.conf=/etc/ceph/ceph.conf,ceph.client_mountpoint=$volumePath,x-systemd.device-timeout=30,x-systemd.mount-timeout=30,noatime,_netdev,rw 0 2
$accessTo with the arbitrary name you chose for the access rule in step 3 above and
$volumePath with ( /volume/_no-group/…) that is also in the share information that you created.
It should look something like this:
none /mnt/ceph fuse.ceph ceph.id=manilashare,ceph.conf=/etc/ceph/ceph.conf,ceph.client_mountpoint=/volumes/_nogroup/fe4f8ad4-2877-4e23-b5d3-46eb8476750b/ab404bac-9584-45f4-8a34-92dfc6 1fbb98,x-systemd.device-timeout=30,x-systemd.mount-timeout=30,noatime,_netdev,rw 0 2
Add the following, substituting the name you chose for the access rule and using the access key from that rule:
[client.$accessTo] key = $accessKey
Your file should look something like this :
[client.manilashare] key = AQAHfhZiwTf/NhAAT5ChE4tDXt3Nq1NyiURbMQ==
