Re: [ceph-users] how to fix active+remapped pg

Update: I noticed that I hadn't increased pgp_num for default data pool for which I increased pg_num time ago. So I did now and some backfilling happened. Now I still have "31 actige+remapped" pgs.

Re: [ceph-users] HBase over CephFS

There are users that have/are running HBase on top of Ceph. The setup should be no different than the standard HBase setup instructions, with the exception that when configuring the Hadoop file system, you specify CephFS instead (typically in core-site.xml). Currently the documentation for runn

Re: [ceph-users] Openstack Havana, boot from volume fails

Hi, I think you have to set the libvirt secret for your ceph UUID on your nova-compute node like e1915277-e3a5-4547-bc9e-4991c6864dc7 client.volumes secret in secret.xml virsh secret-define secret.xml and set the secret virsh secret-set-value e1915277-e3a5-4547-bc9e-4991c6864dc

[ceph-users] Ceph management tools

I am doing some distributed storage research for a client and was wondering if you guys could point me to any Web/GUI tools that can be used to configure/manage/monitor Ceph clusters. Also, in your opinion how does Ceph stack up to GlusterFS and Apache Hadoop? It seems as Ceph and Gluster are usin

I'm also getting similar problems, although in my installation, even though there are errors, it seems to finish. (I'm using centos 6.4 and emperor release and I added the "defaults http and https" to the sudoers file for the ia1 node, though I didn't do so for the the ia2 and ia3 nodes.) So is eve

Re: [ceph-users] ceph-deploy problems on CentOS-6.4

Those aren't really errors, when ceph-deploy runs commands on the host anything that gets printed to stderr as a result is relayed back through ceph-deploy with the [ERROR] tag. If you look at the content of the errors it just has the output of the commands that were run in the step beforehand.

Hi Knut, I have it on my "to-do" list to write a free open-source Ceph web GUI (in django). There is a ceph admin REST api that seems like all management functionality is exposed. I've yet to write a blueprint, but if you are interested in contributing, I'd love the help. https://github.com/do
