ceph | distributed object , block , and file storage platform | Storage library

I am currently struggling with a problem I am having with rest calls to an AWS s3 API hosted by a rados/ceph gateway.

For reasons I wont go into, I can't use an SDK that is provided to talk to it, which would solve all of my woes - I'm recreating some of the more simple jobs I need via CURL - which in the most part work, I can make buckets, delete them, add objects, create roles but my newest problem is bucket policies, both GET for them and PUT. I receive a 403 every time and I cannot figure out why.

What I have attempted to do is use another box with an SDK that talks to the API (boto3) and the AWS s3API calls to do the same thing and they work perfectly fine with the users Access and Secret key, so I do not think its an account thing.

Using the logs from the SDK jobs, I have attempted to recreate everything that is being sent, headers, payload etc...

Now I can only think that as a 403 maybe its the Auth4 strategy but .... this strategy works for every other job I need to do.

Code:

Ceph cluster shows following weird behavior with ceph df output:

I implemented Ceph Pacific Stable 6.0 with Ceph-Ansible on Ubuntu 20.04 LTS but when I want to change size of my pool from 3 to 1 with following command:

I'm trying to share a cephfs volumes between namespaces within k8s cluster. I'm using ceph-csi with cephfs.

Followed https://github.com/ceph/ceph-csi/blob/devel/docs/static-pvc.md#cephfs-static-pvc to create static pv+pvc in both namespaces. Works if I don't launch both pods on same node.

If both pods on same node, Second pod get stuck with error:

I am trying to create a GKE with a preconfigured local SSD configuration - namely I'd like for the devices to use the NVMe interface and do not format/mount the devices.

The gcloud alpha container clusters create command, as documented here, has a command line option called --local-ssd-volumes which supports these options.

A example is provided:

I am applying this bluestore_min_alloc_size to 4096, no matter how I apply the setting, it not getting picked up by daemons, I have tried to restart all daemons pod also after applying the setting but no effect.

i hope you're doing okay

im trying to build a cdap image that i havein gitlab in aks using argocd

the build works in my local kubernetes cluster with rook-ceph storage class but with managed premium storage class in aks it seems that something is wrong in permissions

here is my storage class :

Trying to install Crunchydata postgres-operator. My pgo-deploy pod is failing with error. I have setup default nfs storage running the following commands, # kubectl create -f rbac.yaml the content is,

I am learning bluestore of ceph. I am trying to use the ceph_object_store to test bluestore. But I see lots of unrelated log output. But I can't see any output related to the benchmark. I found the benchmark uses dout(0) to print log. So how could I close the unrelated log output and set the benchmark to print?

Those unrelated log output likes:
