Hi Adam!
In addition to my earlier question of is there a way of trying a more
targeted upgrade first so we don't risk accidentally breaking the
entire production cluster,
`ceph config dump | grep container_image` shows:
global
basic container_image

Thanks! Is there a way of trying out the update on one osd first to make
sure we don't nuke the entire production cluster?

From the ceph versions output I can see

It seems like all the OSD daemons on this cluster are using that

Yes, I'd love this!
A lot of companies want samba for simple file access from windows/mac
clients. I know quite some companies that buy netapp as 'easy smb storage'.
Having ceph do built-in (or bolt-on) samba instead of having to manage
external samba clusters would be nice, and would make it
I missed a step in the calculation. The total_memory_kb I mentioned
earlier is also multiplied by the value of the

all the daemons. That value defaults to 0.7. That might explain it seeming

I am new to ceph and I am looking to monitor the user/bucket usage for ceph.

Hi, Eric Ivancich
I have similar problem in ceph version 16.2.5. Has this problem been
completely resolved in Pacific version？
Our bucket has no lifecycle rules and no copy operation. This is a very serious
data loss issue for us and It happens occasionally in our environment.

Hi Adam.
So doing the calculations with what you are stating here I arrive at a
total sum for all the listed processes at 13.3 (roughly) gb, for everything
except the osds, leaving well in excess of +4gb for each OSD.
Besides the mon daemon which i can tell on my host has a limit of 2gb ,

Hello Daniel,
The situation is not as bad as you described. It is just
PG_BACKFILL_FULL, which means: if the backfills proceed, then one osd
will become backfillfull (i.e., over 90% by default).
This is definitely something that the balancer should be able to
resolve if it were allowed to act. Yo
The backfilling was caused by decommissioning an old host and moving a
bunch of OSD to new machines.
Balancer has not been activated since the backfill started / OSDs were
moved around on hosts.
Busy OSD level ? Do you mean fullness? The cluster is relatively unused in
terms of business.
# ceph
Hi Daniel,
Changing pg_num when some OSD is almost full is not a good strategy (or
even dangerous).
What is causing this backfilling? loss of an OSD? balancer? other ?
What is the least busy OSD level (sort -nrk17)
Is the balancer activated? (upmap?)
Once the situation stabilizes, it becomes i
yes, you can deploy an ingress service with cephadm [1].
You can customize the haproxy config if you need something specific [2].

Afaik cephadm's only viable option is podman. As I undertand, podman does
nothing with managing tasks that can move to other hosts automatically. W
Hey,
I'm running ceph version 18.2.1 (reef) but this problem must have existed a
long time before reef.
The documentation says the autoscaler will target 100 pgs per OSD but I'm
only seeing ~10. My erasure encoding is a stripe of 6 data 3 parity.
Could that be the reason? PGs numbers for that EC
Hi,
If I'm correct in a S3 installation it's good practice to have a HA proxy,
I also read somewhere the cephadm tool can deploy the HA Proxy.
But is it a good practice to use cephadm to deploy the HA Proxy or it's
better do deploy it manually on a other server (who does only that).
