What do you do at 11:39 to fix the ceph command from hanging?
I'm having exactly the same problem but you didn't explain how you fixed it!

Great tutorials! I love it. Can you make a tutorial how to customize KV engine(for example, use a rocksdb build from modified source code) of blue store or other storage engines?

I have a ceph cluster setup on AWS ec2 and is able to mount rbds with the Private IPs of instances having monitors, but not able to with Public IPs. What am I missing

[Handelsbilanzdefizit]

I tried this on a new (fresh installed) debian11 system as root:
"apt install ceph ceph-common" --> "packages have unmet dependencies"

How can this be? 🤔

Also I have another question too. Why you create monmap and monkey in tmp directory? It will be remove from system after a reboot. Is not neccessary they be remained in system for feauter?

[Ne_Vectr]

what can happen on ceph which needs user interaction? what to do to not freak out when self-healing isn't working?

Thank you for sharing that was great. There is a questìon here . I i want add node4 to this cluster, should I easily add its hostname and IP address to   /etc/ceph/ceph.conf and update monmap with monmaptool like this : " monmaptool --add {node2-id} {node2-ip} --fsid {cluster uuid} /tmp/monmap ", and following steps as we did for node2 and node3 in "Setting up more nodes" section
Is it enough for adding a new node to an ezisting cluster ?

Hey Daniel, How are you doing? Great Video! I just followed this tutorial today with Ceph Version 17 (Quincy). I noticed one issue: When I load the dashboard, I get messages in the browser that the main.js and style.css files are not of the correct size. It seems ceph mgr is timing out after 20 seconds. Can we update this timeout value somewhere, so that I give the browser more time to download the complete JS or CSS file?
Warm regards,
Guus

[srinivassivakumar]
