Interesting performance increase! I'm Iscsi it at a few installations and now a
wonder what version of Centos is required to improve performance! Did the
cluster go from Luminous to Mimic?

Hi all!
I'm thinking about building a learning rig for ceph. This is the parts list:
PCPartPicker Part List: https://pcpartpicker.com/list/s4vHXP
TL;DR 8 Core 3Ghz Ryzen CPU, 64 Gb RAM, 2Tb x 5 HDDs, 1 240Gb SSD in a
tower case.
My plan is to build a KVM-based setup, both for ceph and workload

The server side encryption features all require special x-amz headers on
write, so they only apply to our S3 apis. But objects encrypted with
SSE-KMS (or a default encryption key) can be read without any x-amz
headers, so swift should be able to decrypt them too. I agree that this
is a bug and
Thanks Jason for the info! A few questions:
"The current rbd-target-api doesn't really support single path LUNs."
In our testing, using single path LUNs, listing the "owner" of a given LUN and
then connecting directly to that gateway yielded stable and well-performing
results, obviously, there

Hello,
I am hoping to expose a REST API to a remote client group who would like to do
things like:
* Create, List, and Delete RBDs and map them to gateway (make a LUN)
* Create snapshots, list, delete, and rollback
* Determine Owner / Active gateway of a given lun
I would run 2-4
Hello,
I have a problem when I want to validate (using md5 hashes) rbd
export/import diff from a rbd source-pool (the production pool) towards
another rbd destination-pool (the backup pool).
Here is the algorythm :
1- First of all, I validate that the two hashes from lasts snapshots

I certainly would, particularly on your SSD's. I'm not familiar with
those Toshibas but disabling disk cache has improved performance on my
clusters and others on this list.
Does the LSI controller you're using provide read/write cache and do
you have it enabled? 72k spinners are likely to see a

Hi John,
I have 9 HDDs and 3 SSDs behind a SAS3008 PCI-Express Fusion-MPT SAS-3 from
LSI. HDDs are HGST HUH721008AL (8TB, 7200k rpm), SSDs are Toshiba PX05SMB040
(400GB). OSDs are bluestore format, 3 HDDs have their wal and db on one SSD (DB
Size 50GB, wal 10 GB). I did not change any cache
