Hi Ceph users!
We are currently configuring our new production Ceph cluster and I have
some questions regarding Ubuntu and NVMe SSDs.
Basic setup:
- Ubuntu 18.04 with HWE Kernel 5.3
- Deployment via ceph-ansible (Ceph stable "Nautilus")
- 5x Nodes with AMD EPYC 7402P CPUs
- 25Gbit/s NICs and s
I suspect Ceph is configured in their case to send all logs off-node to a
central syslog server, ELK, etc.
With Jewel this seemed to result in daemons crashing, but probably it’s since
been fixed (I haven’t tried).

Hello Martin,
I suspect you're using a central syslog server.
Can you share information which central syslog server you use?
Is this central server running on ceph cluster, too?
Regards
Thomas

Hello List,
i use rbd-mirror and i asynchronously mirror to my backup cluster.
My backup cluster only has "spinnung rust" and wont be able to always
perform like the live cluster.
Thats is fine for me, as far as it´s not further behind than 12h.
vm-194-disk-1:
global_id: 7a95730f-451c-4973-8
I suppose the correct syntax is that anything after "client." is the
name? So:
ceph fs authorize cephfs client.bob / r / rw
Would authorize a client named bob?
Yes, exactly:
admin:~ # ceph fs authorize cephfs client.bob / r / rw
[client.bob]

Hello Thomas,

So, I thought I’d post with what I learned re: what to do with this problem.
This system is a 3-node Proxmox cluster, and each node had:
1 x 1TB NVMe
2 x 512GB HDD
I had maybe 100GB of data in this system total. Then I added:

Hi.
I'm experiencing some kind of a space leak in Bluestore. I use EC,
compression and snapshots. First I thought that the leak was caused by
"virtual clones" (issue #38184). However, then I got rid of most of the
snapshots, but continued to experience the problem.
I suspected something when

Hi Steve,
Thanks, it's an interesting discussion, however I don't think that it's
the same problem, because in my case bluestore eats additional space
during rebalance. And it doesn't seem that Ceph does small overwrites
during rebalance. As I understand it does the opposite: it reads and

Great work! Thanks to everyone involved!
One minor thing I've noticed so far with the Ubuntu Bionic build is it's
reporting the release as an RC instead of being 'stable':
