Hi! Sorry for the dumb question, could you point me out to the Python
APIs reference docs for the object store?
Do you have example to share for reading files/dirs?
Thanks,
Giuseppe

Hi all,
I want to connect an openstack Folsom glance service to ceph.
The first option is setting up the glance-api.conf with 'default_store=rbd' and
the user and pool.
The second option is defined in

Hi,
I have problems with "ceph-deploy gatherkeys" in cuttlefish. When I run

on my admin node, I get

Hi,
perhaps a silly question, but am I right that the osd have to be mounted
via fstab?
Today I started my testcluster and it worked after mounting the
OSD-partitions manually.
Greetings,

It shouldn't matter. The OSDs are generally activated when the disk is
mounted, however that happens.

howdy, y'all.
we are testing ceph and all of its features. we love RBD! however cephFS,
though clearly stated not production ready, has been stonewalling us. in an
attempt to get rolling quickly, we followed some guides on CephFS (

Holy cow.
Thank you for pointing out what should have been obvious. So glad these
emails are kept on the web for future searchers like me ;)

Hi,
We are currently testing the performance with rbd caching enabled with
write-back mode on our openstack (grizzly) nova nodes. By default, nova fires
up the rbd volumes with "if=none" mode evidenced by the following cmd line from
"ps | grep".

Hi Greg,
thanks for this very useful hint. I found the origin of the problem and
will open a bug report in Redmine.

I'm having issues with data corruption on RBD volumes again.
I'm using RBD volumes for virtual harddisks for qemu-kvm virtual machines.

I've added that instruction to the docs. It should be up shortly. Let

Hi,
I had this happen the first time I tried to deploy to CentOS/RHEL
system. Are you running one of these systems?
I found that by turning off iptables, and disabling selinux, this
allowed me to get my test cluster up and running. Not sure if that's the
best approach for production however.

I am new to ceph but loving every moment of it. I am learning all of this
