Just for completeness for anyone that is following this thread. Igor
added that setting in Octopus, so unfortunately I am unable to use it
as I am still on Nautilus.

Thanks Igor for the tip. I'll see if I can use this to reduce the
number of tweaks I need.

32GB for a dedicated node that only runs mon / mgr daemons; no OSDs. I’ve
experienced a cluster that grew over time such that 32GB was enough to run
steady-state, but as OSDs and PGs were added to the cluster it was no longer
enough to *boot* the daemons and I had to do emergency upgrades to 6

Hallo everybody,
the official documentation recommends for the monitor nodes 32GB for a

Like i would need 3 nodes with 32GB RAM each in addition to the OSD nodes?

Hi,
I've setup a ceph cluster using cephadmin on three ubuntu servers. Everything
went great until I tried to activate a osd prepared on a lvm.
I have prepared 4 volumes with the command:

Now I try to activate one of them with the command (followed by th
Yes, I did end up destroying and recreating the monitor.
As I wanted to use the same IP it was somewhat tedious as I had to
restart every OSD so they will catch the new value for mon_host.
Is there any way to tell all OSD that mon_host has a new value without
restarting them?

Hello Robert,
thank you for your reply, so what am I missing?

Either nearly 14TB total pool size knowing, that in case of a lost node, there will be no re-distribution du

Hi Frank, yes I changed the device class to HDD but there seems to be some

based on the class but some other internal mechanism.
However, I did apply the class after creating the osd, rather than during.

Hi everyone.
I try to understand conception of RBD group snapshots, but I can’t.
Regular snaps (not a group one) we can use like regular RBD images. We can
export it or use it directly in qemu-img or we can create new image based on
snap (clone).
But if we talk about group snaps – we can’t do any
