Hey all,
I wanted to confirm my understanding of some of the mechanics of
backfill in EC pools. I've yet to find a document that outlines this
in detail; if there is one, please send it my way. :) Some of what I
write below is likely in the "well, duh" category, but I tended
towards completeness.
Hi,
I also have used bcache extensively on filestore with journals on SSD
for at least 5 years. This has worked very well in all versions up to
luminous. The iops improvement was definitely beneficial for vm disk
images in rbd. I am also using it under bluestore with db/wal on nvme
on both
This is what I have when I query prometheus, most hdd's are still sata 5400rpm,
there are also some ssd's. I also did not optimize cpu frequency settings.
(forget about the instance=c03, that is just because the data comes from mgr
c03, these drives are on different hosts)

Good evening,
I've to tackle an old, probably recurring topic: HBAs vs. Raid
controllers. While generally speaking many people in the ceph field
recommend to go with HBAs, it seems in our infrastructure the only
server we phased in with an HBA vs. raid controller is actually doing
worse in
Thanks for the answer. It seems very easy.
I've never played with rocksdb options before. I always used default
and I think I need to play more with it but I couldn't find a good
config reference to understand at ceph side.
Can I use this guide instead?
Hi All,
I want to send Ceph logs out to an external Graylog server. I’ve configured
the Graylog host IP using “ceph config set global log_graylog_host x.x.x.x” and
enabled logging through the Ceph dashboard (I’m running Octopus 15.2.9 –
container based). I’ve also setup a GELF UDP input on
So that's a bug ;)
https://github.com/ceph/ceph/blob/master/src/ceph-volume/ceph_volume/devices/lvm/activate.py#L248-L251
This doesn't honor the --no-systemd flag.
But this should work when you're not using the --all option.

thanks by commenting the ProtectClock directive, the issue is resolved.
Thanks for the support.

Hey Dimitir,
because --no-systemd still requires systemd:
[19:03:00] server20.place6:~# ceph-volume lvm activate --all --no-systemd
--> Executable systemctl not in PATH:
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
--> FileNotFoundError: [Errno 2] No such file or directory:
Hi,

Why not using the --no-systemd option during the ceph-volume activate
command?
The systemd part is only enabling and starting the service but the tmpfs
part should work if you're not using systemd
Hello.
I'm trying to fix a wrong cluster deployment (Nautilus 14.2.16)
Cluster usage is %40 EC pool with RGW
Every node has:
20 x OSD = TOSHIBA MG08SCA16TEY 16.0TB
2 x DB = NVME PM1725b 1.6TB (linux mdadm raid1)
NVME usage always goes around %90-99.
With "iostat -xdh 1"

The best questions are the ones that one can answer oneself.
The great documentation on
https://docs.ceph.com/en/latest/dev/ceph-volume/lvm/
gives the right pointers. The right search term is "lvm list tags" and
results into something like this:
[15:56:04] server20.place6:~# lvs -o lv_tags
Hi Sebastian,
Thank you. Is there a way to create more than 1 rgw per host until this
new feature is released?

Hi,
You have 2 ways:
First is using s3vrowser app and in the menu select the multipart uploads and
clean it up.
The other is like this:
Set lifecycle policy
On the client:

Good morning,
is there any documentation available regarding the meta data stored
within LVM that ceph-volume manages / creates?
My background is that ceph-volume activate does not work on non-systemd
Linux distributions, but if I know how to recreate the tmpfs, we can
easily start the osd
Anyone an idea? :)

Hi Istvan,
both of them require bucket access, correct?
Is there a way to add the LC policy globally?
Cheers

I've a RGW bucket (versioning=on). And there was objects like this:

Hi,
is there a way to remove multipart uploads that are older than X days?
It doesn't need to be build into ceph or is automated to the end. Just
something I don't need to build on my own.
I currently try to debug a problem where ceph reports a lot more used space
than it actually requires (

This should help:
ceph config set mgr mgr/balancer/upmap_max_deviation 1
