[ceph-users] Reduce the size of the pool .log

It seems that the pool .log increases in its size as ceph runs over time. I've using 20 placement groups (pgs) for the .log pool. Now it complains that "HEALTH_WARN pool .log has too few pgs". I don't have a good understanding on when ceph will remove the old log entries by itself. I saw some

[ceph-users] Recommended way of leveraging multiple disks by Ceph

Hi, I'd like to run Ceph on a few machines, each of which has multiple disks. The disks are heterogeneous: some are rotational disks of larger capacities while others are smaller solid state disks. What are the recommended ways of running ceph osd-es on them? Two of the approaches can be: 1)

[ceph-users] OSD refuses to start after problem with adding monitors

Hi, I started a new Ceph cluster with a single instance, and later added two new osd on different machines using ceph-deploy. The osd data directories reside on a separate disk than the conventional /var/local/ceph/osd- directory. Correspondingly, I changed the replication factor size to 3

[ceph-users] Ceph/Radosgw v0.94 Content-Type versus Content-type

I noticed that S3 Java SDK for getContentType() no longer works in Ceph/Radosgw v0.94 (Hammer). It seems that S3 SDK expects the metadata “Content-Type” whereas ceph responds with “Content-type”. Does anyone know how to make a request for having this issue fixed? Fangzhe

[ceph-users] Migrating data into a newer ceph instance

Hi, We have been running Ceph/Radosgw version 0.80.7 (Giant) and stored quite some amount of data in it. We are only using ceph as an object store via radosgw. Last week cheph-radosgw daemon suddenly refused to start (with logs only showing initialization timeout error on Centos 7). This
