hi Corin. We run latest hammer on CentOS7.2, with 3 mons and have not
seen this problem. I'm not sure if there are any other possible
differences between the healthy nodes and the one that has excessive
consumption of memory? thx will

Hi list, I wonder if there is anyone who have experience with Intel
P3700 SSD drives as Journals, and can share their experience?
I was thinking of using the P3700 SSD 400GB as journal in my ceph
deployment. It is benchmarked in Sebastian hann ssd page as well.
However a vendor I spoke to didn't q

Hi Nick, I found the graph very useful explaining the concept. thx for sharing.

18x1.8TB Hitachi Spinning 10k SAS. My OSD:Journal ratio would be 3:1.

Hi Jelle, we do Arista 7050TX 10GbE Switching as TORs. We cluster them

distances, for us coppe

Hi Nick. I did try intel_idle.max_cstate=0, and I've got quite a
significant improvement as attached below. Thanks for this advice!
This is still with DIRECT=1, SYNC=1,

Hi Cephers,
I got problem removing /var/lib/ceph/osd/ceph-53 dir which was used by
OSD.53 that I have removed.
The way that I remove the OSD:
1. ceph osd out 53
2. sudo service ceph stop osd.53
3. ceph osd crush remove osd.53
4. ceph auth del osd.53
5. ceph osd rm 53
6. sudo umount /var/lib/ceph/
--osd-journal=/dev/sdc5
Does anyone knows why it doesn't work if I map the journal using
/dev/disk/by-partuuid/xxx-xxx ?
Thanks.
