Is this a bug report or feature request?

• Feature Request

What should the feature do:
We have per node configuration for selecting device, but no wal/db device selection. We can add configuration for what device will be used for wal/db device.

// current
    nodes:
    - name: "mynode"
      devices:
      - name: "sdb"

// fix to
    nodes:
    - name: "mynode"

Bug Report

When creating cephfs data pools with erasure code instead of replication, the wrong command is constructed by the create_mds_filesystems.yml task.

Expected command:

ceph --cluster ceph osd pool create cephfs_data 8 8 erasure default

Constructed command:

cep

Feature Request

It'd be nice to have a special ceph image that has all the debug packages and the right tooling to perform troubleshooting.
The packages are:

*-debuginfo

• ceph-test
• strace
• perf
• other?

The idea is to pull that image and start debugging crashing/failing daemons or just

Is this a BUG REPORT or FEATURE REQUEST?:
Create Profile with invalid storage dataType: FAIL (No proper hint message why it is failing. For Ex: if you see, it validates for name datatype)

Enhancement Suggestion

Currently if Rome does not find a dependency or bcsymbolmap in the cache it outputs this as an error, and this is particularly ugly when used with Fastlane.

It is just noise in almost all cases I can think of, and is particularly noisy when you do your first Rome download and when you build only for one platform e.g. iOS where you get all the symbol map errors.

Describe the feature you'd like to have

Go Report Card shows nice statistics about the code quality of the project. There are a few sections that do not reach 100%. This can easily be addressed, after which the configuration for the tests configuration in scripts/golangci.yml and similar can be updated.

What is the value to

A task I've found error-prone and also poorly documented is decommissioning worker/master nodes in a cluster. It'd be really helpful to have some kurl-specific docs on https://kurl.sh/docs.

Also rebooting worker/master nodes.

librbd offers a way to get notified in case the metadata of an RBD image changes. rbd_update_watch() can be used to setup a callback so that the application can get informed.

The internal/callbacks package should be useful for implementing this.

Please provide docs for various volplugin REST endpoints. It will be nice to document

• Volplugin Operation
• URL
• Request type (POST, GET, PUT, DELETE)
• Input JSON
• Output JSON
• Errors returned including http status codes

start cluster on Mac hangs with minikube. docker container started, but the correct ip is vm ip, not the host ip. minikube ip is 192.168.64.28 on my laptop. 192.168.2.2 is the host ip.

As the sole active maintainer, I'm looking for co-maintainers for the project to push features faster.
Please ping me if you're interested.

It'd be awesome if you have already contributed to the project and interested. Otherwise, there would be a brief probation period after starting contributing to the project.

The latest sizing recommendation is that bluestore DB partitions should not be smaller then 4% of the size of the data partition. We should consider this in our default deployments, maybe even check if this recommendation is not met.

We need a full How-To on how to setup everything including the Ceph part. This should also include all the keyring/auth/pool handling.
