The way I did this was to use:
ceph-volume lvm batch /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde
/dev/sdf etc
Where you just list all of the block devices you want to use in a group. It
will automatically determine which devices are SSD and then automatically
partition it for you and share it am
Hello guys,
is there anyone using Telegraf / InfluxDB metrics exporter with Grafana
dashboards? I am asking like that because I was unable to find any
existing Grafana dashboards based on InfluxDB.
I am having hard times with creating graphs I want to see. Metrics are
exported in way that every s
Hi!
While browsing /#/pool in nautilus ceph dashboard I noticed it said 93%
used on the single pool we have (3x replica).
ceph df detal however shows 81% used on the pool and 67% raw useage.

Interesting. What did the partitioning look like?

It just uses LVM to create a bunch of LVs. It doesn't actually create
separate partitions on the block devices. You can run the command and it
will give you a preview of what it will do and ask for confirmation.

Just also a bit curious. So it just creates a pv on sda and no
partitioning done on sda?

oh very nice!
I tried it out with "batch --report" options, using 1 sdd and 3 hds. (and ceph
nautilus)
it gave me this:

tcmu-runner iGW is seen behaving as a generic iSCSI target, seen from
vSphere, with dataflow on 1 AO and n ANO's as "hot-standby" for each
LUN.
Load-balance is therefore limited to be between images, if you use
tcmu-runner based deployment.
Each LUN will have one AO(Active-Optimized) path and n n
Hi,
I enabled telegraf and influx plugins for my ceph cluster.
I would like to use influx/chronograf to detect anomalies:
- osd down
- monitor down
- osd near full
But it is very difficult/complicated to make simple queries because, for
example I have osd up and osd total but not osd down metric.

I also think there's a bug in the balancer plugin as it seems to have
stopped for me also. I'm on Luminous though, so not sure if that will
be the same bug.
The balancer used to work flawlessly, giving

To determine how much osds down you don't need special metric, because
you already
have osd_up and osd_in metrics. Just use math.

Is the daemon running? You can check for the process to be alive in
/var/run/ceph/ceph-mon.$hostname.asok
If so ... then query the monitor for its status:
ceph daemon mon.$hostname quo
