Hello!
We are using Ceph RBD kernel module, on RHEL 7.0, with Ceph "Firefly"
0.80.5..
Does RBD kernel module support Cache Tiering in Firefly?
If not, when will RBD kernel module support Cache Tiering (Linux kernel
version and Ceph version)?

Hello!
In a two (2) rack Ceph cluster, with 15 hosts per rack (10 OSD per
host / 150 OSDs per rack), is it possible to create a ruleset for a
pool such that the Primary and Secondary PGs/replicas are placed in
one rack and Tertiary PG/replica is placed in the other rack?

Greg,
So is the consensus that the appropriate way to implement this scenario is
to have the fs created on the EC backing pool vs. the cache pool but that
the UI check needs to be tweaked to distinguish between this scenario and
just trying to use a EC pool alone?
I'm also interested in the scena
Hi
Does anyone know how to check the basic cache pool stats for the information
like how well the cache layer is working for a recent or historic time frame?
Things like cache hit ratio would be very helpful as well as.
Thanks

Hi,
I have some strange OSD problems. Before the weekend I started some
rsync tests over CephFS, on a cache pool with underlying EC KV pool.
Today the cluster is completely degraded:

Hi all,
I have no idea why running out of filehandles should produce a "out of
memory" error, but well. I've increased the ulimit as you told me, and
nothing changed. I've noticed that the osd init script sets the max open
file handles explicitly, so I was setting the corresponding option in my

Hi there,
I am new to Ceph and in general to Cloud Storage.
I want to know that is there different Ceph configuration for variant
DC storage needs? By DC storage needs I mean, for example Reliability
or High performance Storage system.
In other words, is there different Ceph configuration if I want
I don't know where the file came from, but likely/unlikely markers are the
kind of micro-optimization that isn't worth the cost in Ceph dev resources
right now.

I agree with Greg. When dealing with the latencies that we deal with due to
different IO operations (networking, storage), it's mostly not worth the
trouble. I think the main reason we didn't actually put it to use is that
we forgot we've had this macro defined, and it really wasn't worth the

Not sure, but have you checked the clocks on their nodes? Extreme
clock drift often results in strange cephx errors.

The pidfile bug is already fixed in master/giant branches.
As for the crashing, I'd try killing all the osd processes and turning
them back on again. It might just be some daemon restart failed, or
your cluster could be sufficiently overloaded that the node disks are
going unresponsive and they're

Thanks Sage! We will test this and share our observations..

If it's true, is there any other tools I can use to check and repair the

Not much, no. That said, you shouldn't really need an fsck unless the
underlying RADOS store went through some catastrophic event. Is there

Thanks for the reply, Greg.
With traditional file system experience, I have to admit it will take me
some time to get used to the way CephFS works. Considering it as part of
my learning curve. :-)
One of concerns I have it that, without tools like fsck, how could we know

CephFS in general has a lot fewer metadata structures than traditional
filesystems generally do; about the only thing that could go wrong
without users noticing directly is:
1) The data gets corrupted
2) Files somehow get removed from folders.
Data corruption is something RADOS is responsible for

Hi all!
As document says, ceph has some default pools for radosgw instance. These pools
are:
* .rgw.root
* .rgw.control
* .rgw.gc
* .rgw.buckets
* .rgw.buckets.index
* .log
* .intent-log
* .usage
* .users
* .users.ema
Great to know you are working on it!
I am new to the mailing list. Is there any reference of discussion last
year, so I can look into. or any bug number I can watch to keep track of
the development?
Thanks,
Brandon
