around L1434).
But, looks like there is another command "ceph pg dump_json {all |

Sure. But it guess it could reduce 'ceph' code size if you use an existing
framework.

I talk about cluster services like 'corosync', which provide membership and
quorum services.
I would say the levels of redundancy could roughly be translated like
this.
RAID0 one replica (size=1)
RAID1 two replicas (size=2)
RAID10 two replicas (size=2)
RAID5 erasure coding (erasure-code-m=1)
RAID6 erasure coding (erasure-code-m=2)

Thanks for the reply.

There is no RAID level for RBDs. These are "virtual" block devices an

Something that is host, osd, mon aware and shows various status of components,

Hi there,
I'm sure that the Ceph community was somewhat excited when Seagate released
their enterprise 6TB SAS/SATA hard drives recently, previously the only other
6TB drives which were available for enterprises were the HGST helium ones which
are nearly impossible to find unless you are buying

Overnight, I tried to use ceph_filestore_dump to export a pg that is
missing from other osds from an osd, with the intent of manually copying
the export to the osds in the pg map and importing.
Unfortunately, what is on-disk 59gb of data had filled 1TB when I got in

Hello Ceph-community,
does it possible to somehow configure RGW to use alternate pools other than
predefined ones? Does it possible add additional pool to RGW to store data in
as it could be done in case of Cephfs?
Thank you very much and best regards!

Ok, thanks for the suggestions, I will try to achieve this in the next
days and I will share my experience with you.

Hit all, I successfully installed a ceph cluster firefly version made up
of 3 osd and one monitor host.
After that I created a pool and 1 rdb object for kvm .
It works fine .
I verified my pool has a replica size = 3 but a I read the default should

Was talking about this. There is a different and simpler rule that we
use nowadays, for some reason it's not well documented:
RewriteRule ^/(.*) /s3gw.3.fcgi?%{QUERY_STRING}
[E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
I still need to see a more verbose log to make a better educated guess.

The replacement is the 1200 series which are more 2x the price but have a SAS
