something weird happened on one of the ceph clusters that i administer
tonight which resulted in virtual machines using rbd volumes seeing
corruption in multiple forms.
when everything was fine earlier in the day, the cluster was a number of
storage nodes spread across 3 different roots in the cru

After thinking, the solution to add "snmp" in the "ceph" group seems to me
better too... _if_ the "ceph" group has never the "w" right in /var/lib/ceph/
(which seems to be the case). So thanks to comfort me
Hi François,
"usermod -aG ceph snmp" is better ;)

Earlier on during newstore/bluestore development we tested with the
rocksdb instance (and just the rocksdb WAL) on SSDs. At the time it did
help, but bluestore performance has improved dramatically since then so
we'll need to retest. SSDs shouldn't really help with large writes
anymore (blues
Mark,
Since most of us already have existing clusters that use SSDs for
journals, has there been any testing of converting that hardware over to
using BlueStore and re-purposing the SSDs as a block cache (like using
bcache)?
To me this seems like it would be a good combination for a typical RBD

Hi Folks,
We are actually in the middle of doing some bluestore testing/tuning for
the upstream jewel release as we speak. :) These are (so far) pure HDD
tests using 4 nodes with 4 spinning disks and no SSDs.
Basically on the write side it's looking fantastic and that's an area we
really wa
Hi Ceph Community,
I am trying to use "ceph -w" output to monitor my ceph cluster. The basic
setup is:
A python script runs ceph -w and processes each line of output. It finds
the data it wants and reports it to InfluxDB. I view the data using
Grafana, and Ceph Dashboard.
For the most part it
Hi Stefan,
We are also interested in the bluestore, but did not yet look into it.
We tried keyvaluestore before and that could be enabled by setting the
osd objectstore value.
And in this ticket http://tracker.ceph.com/issues/13942 I see:

Hello everyone!
I think that the new bluestore sounds great and would like to try it out in my
test environment but I didn't find anything how to use it but I finally managed
to test it and it really looks promising performancewise.
If anyone has more information or guides for bluestore please t
Hey cephers,
Just a reminder that there are still a couple of slots left if you

Reply to myself !
In fact i had an overlay in top of my ssd pool & hdd pool.
The guy who installed this ceph cluster created some objects in the hdd pool
but didn't removed them before applying the overlay,
so the objects was not listed in the rbd ls but when i removed the overlay a
