[ceph-users] Too strong permission for RGW in OpenStack

Hi. We have ceph cluster with a lot of users who use S3 and RBD protocols. Now we need to give access to one use group with OpenStack, so they run RGW on their side, but we have to set "ceph caps" for this RGW. In the documentation for OpenStack is following ceph auth get-or-create client.ra

[ceph-users] Re: Cephadm - Adding host to migrated cluster

That doesn't sound right. I had a single node cluster deployed with 16.2.5 and tried to reproduce. I only installed cephadm and copied the cephadm public key to the new node and added it to the cluster via dashboard. Then I added some disks to it and they were successfully deployed as OSDs.

[ceph-users] Balancing MDS services on hosts

[ceph-users] Re-install host OS on Ceph OSD node

Good day I have a ceph osd node with an OS drive that has errors and may soon fail. There are 8 x 18TB drives installed in this node. The journal's for each drive are co-located on each drive. I'd like to replace the falling OS drive, re-install the OS (same node name and IP addressing), push the

Hello Adam, Just tried command ceph orch redeploy (without "--image") and it works, the rgw image is the right version. The command we used is $ sudo ceph orch daemon redeploy rgw.testrgw.svtcephrgwv1.zlfzpx quay.io/ceph/ceph:v16.2.10 The old rgw service is still alive, but it seems that i

Dear all, I am deploying a Ceph system for the first time. I have 3 servers where I intend to install 1 manager, 1 mon and 12 OSDs in each. Since they are used in production already, I selected a single machine to begin deployment, but got stuck when creating rbd pools. The host OS is Cen

[ceph-users] Quincy 22.04/Jammy packages

Curious if there is a timeline for when quincy will start getting packages for Ubuntu Jammy/22.04. It looks like quincy started getting builds for EL9 with 17.2.4, and now with the 17.2.5 there are still only bullseye and focal dists available. Canonical is publishing a 17.2.0 build in jammy-upd

Hi, the command doesn't return because your PGs are inactive. It looks like you're trying to use the default replicated_rule but it can't find a suitable placement. What does your 'ceph osd tree' look like? And also paste your ruleset ('ceph osd crush rule dump replicated_rule'). Regardin
