Hi All,
I have a ceph storage cluster with four nodes. I have created block storage
using cinder in openstack and ceph as its storage backend.
So, I see a volume is created in ceph in one of the pools. But how to get
information like on which OSD, PG, the volume is created in ?
Thanks
Kumar
Hi,
some of the osds in my env continues to try to connect to monitors/ceph nodes,
but get connection refused and down/out. It even worse when I try to initialize
100+ osds (800G HDD for each osd), most of the osds would run into the same
problem to connect to monitor. I checked the monitor sta

Thanks, trying that now.
I noticed that using = 0.01 in ceph.conf

Hi,
During a multi part upload you can't upload parts smaller than 5M, and
radosgw also slices object in slices of 4M. Having those two being
different is a bit unfortunate because if you slice your files in the
minimum chunk size you end up with a main file of 4M and a shadowfile
of 1M for each
Hello Ian,

Actually, we are not ready to do that yet.

Hello,
How can check ceph client session in clients side, for example, when
mount iscsi or nfs, you can check it (nfs just mount, iscsi iscsiadm -m
session), but how can do that with ceph? And is there more detailed
documentation about openstack and ceph than

Hi All,
I have a ceph storage cluster with four nodes. I have created block storage
using cinder in openstack and ceph as its storage backend.
So, I see a volume is created in ceph in one of the pools. But how to get
information like on which OSD, PG, the volume is created in ?
Thanks

Do you have some advice about how to use the snap trim throttle? I saw
osd_snap_trim_sleep, which is still 0 by default. But I didn't manage to follow
