hello all!
As the documentation said One of the unique features of Ceph is that it
decouples data and metadata.for applying the mechanism of decoupling, Ceph
uses Metadata Server (MDS) cluster.MDS cluster manages metadata operations,
like open or rename a file
On the other hand, Ceph

Hi All,
Hoping someone can help me understand CEPH HA or point me in the direction
of a doc I missed.
I understand how CEPH HA itself works in regards to PG, OSD and Monitoring.
However what isn't clear for me is the failover in regards to things like
iSCSI and the not yet production ready

Folks,
I am having a hard time setting up a fresh install of GIANT on a fresh install
of RHEL7 - which you would think would be about the easiest of all situations...
1. Using ceph-deploy 1.5.22 - for some reason it never updates the
/etc/yum.repos.d to include all of the various ceph
Hi Justin,
I could probably be wrong on this but you're having to use a Ceph gateway
rather than natively interracting with the cluster right? If so then the
only way that you'd really be able to get HA would be to install a load
balancer in front of multiple gateways. Under normal conditions
OK, apparently it's also a good idea to install EPEL, not just copy over the
repo configuration from another installation.
That resolved the key error and It appears that I have it all installed.

Hi Justin,
Ceph, proper, does not provide those services. Ceph does provide Linux block
devices (look for Rados Block Devices, aka, RBD) and a filesystem, CephFS.
I don’t know much about the filesystem, but the block devices are present on an
RBD client that you set up, following the
Thank you all!!
This all makes more sense now. I think I know the direction where we are
heading.

Key problem resolved by actually installing (as opposed to simply configuring)
the EPEL repo. And with that, the cluster became viable. Thanks all.

HI,
I'm currently testing Firefly 0.80.9 and noticed that OSD are not
auto-mounted after server reboot.
It used to mount auto with Firefly 0.80.7. OS is RHEL 6.5.
There was another thread earlier on this topic with v0.80.8, suggestion was
to add mount points to /etc/fstab.
Question is whether
