thanx Nick, Gregory and Wido,
So at least, we can say the cache tiering in Jewel is stable enough
I think.
I like cache tiering more than the others, but yes, there is a problem
about cache tiering in
flushing data between different nodes, which are not a problem in local
caching solution.

You should subtract buffers and cache from the used memory to get a more
accurate representation of how much memory is actually available to
processes. In this case that puts you around 22G of used - or a better term
might be unavailable memory. Buffers and cache can be reallocated when
needed - it
Hi,
I'm working on an rbdmap change https://github.com/ceph/ceph/pull/13361,
and would appreciate some input from existing users.
Currently "rbdmap map" maps any RBD images listed in the rbdmap config
file (RBDMAPFILE), whereas "rbdmap unmap" unmaps all mapped RBD images,
regardless of whether th
In the case where the rbdmap utility is invoked by systemd (i.e. to
map RBD devices on system startup and unmap RBD devices on system
shutdown) [1], I would think the current unmap-all behavior is
desirable in much the same way that only filesystems listed in
"/etc/fstab" are mounted at startup but
Hi, Muthusamy Muthiah
I'm not totally sure that this is a memory leak.
We had same problems with bluestore on ceph v11.2.0.
Reduce bluestore cache helped us to solve it and stabilize OSD memory
consumption on the 3GB level.
Perhaps this will help you:
bluestore_cache_size = 104857600

Hi Noah,
I'm trying to follow your example where you can pass a LUA script as json

rados permission denied error saying its failed to read the test object I
have placed on the pool.
I have also tried calling the cls_hello ob

Hi Nick,
First thing to note is that in Kraken that object classes not whitelisted
need to be enabled explicitly. This is in the Kraken release notes (
http://docs.ceph.com/docs/master/release-notes/):
tldr: add 'osd class load list = *' and 'osd class default list = *' to
ceph.conf.
- The ‘osd
Hi all,
I would like to integrate radosgw with hadoop.
We are using 2.7.3 version of hadoop. So, s3a can be suitable plugin.
But, I can't find any guide for it.
Could anybody help me?
Thanks.
