Hi Don,
Did you configure target_ dirty_ratio, target_full_ratio and
target_max_bytes?

Hi
I was doing some testing on erasure coded based CephFS cluster. cluster is
running with giant 0.87.1 release.

Hi sage,
When can we expect the fully functional fsck for cephfs?. Can we get at
next major release?. Is there any roadmap or time frame for the fully
functional fsck release?
Thanks & Regards

Hi Markus,
X10DRH-CT can support only 16 drive as default. If you want to connect more
drive,there is a special SKU for more drive support from super micro or you
need additional SAS controller. We are using 2630 V3( 8 core - 2.4GHz) *2
for 30 drives on SM X10DRI-T. It is working perfectly on repl

We are getting "store is getting too big" on our test cluster. Cluster is

We have created EC pool ( k =10 and m =3) with 540 osds. We followed the
following rule to calculate the pgs count for the EC pool.
(OSDs * 100)
Total PGs =
pool size
Where *pool size* is either the number of replicas for replicated poo
Hi all,
We are building EC cluster with cache tier for CephFS. We are planning to
use the following 1U chassis along with Intel SSD DC S3700 for cache tier.
It has 10 * 2.5" slots. Could you recommend a suitable Intel processor and
amount of RAM to cater 10 * SSDs?.

Hi all,
We are trying to create 2 PB scale Ceph storage cluster for file system
access using erasure coded profiles in giant release. Can we create Erasure
coded pool (k+m = 10 +3) for data and replicated (4 replicas) pool for
metadata for creating CEPHFS? What are the pros and cons of using two
