Re: [ceph-users] Recommended way to use Ceph as storage for file server

We have an NFS to RBD gateway with a large number of smaller RBDs. In our use case we are allowing users to request their own RBD containers that are then served up via NFS into a mixed cluster of clients.Our gateway is quite beefy, probably more than it needs to be, 2x8 core cpus and 96GB

[ceph-users] ceph-deploy 1.5.4 (addressing packages coming from EPEL)

Hi All, We've experienced a lot of issues since EPEL started packaging a 0.80.1-2 version that YUM will see as higher than 0.80.1 and therefore will choose to install the EPEL one. That package has some issues from what we have seen and in most cases will break the installation process. There

More detail to this. I recently upgraded my Ceph cluster from Emperor to Firefly. After the upgrade had been done, I noticed 1 of the OSD not coming back to life. While in the process of troubleshooting, rebooted the osd server and the keyring shifted. My $ENV. 4x OSD servers (each has 12, 1

Re: [ceph-users] perplexed by unmapped groups on fresh firefly install

Miki, osd crush chooseleaf type is set to 1 by default, which means that it looks to peer with placement groups on another node, not the same node. You would need to set that to 0 for a 1-node cluster. John On Sun, Jun 8, 2014 at 10:40 PM, Miki Habryn dic...@rcpt.to wrote: I set up a

Re: [ceph-users] failed assertion on AuthMonitor

Barring a newly-introduced bug (doubtful), that assert basically means that your computer lied to the ceph monitor about the durability or ordering of data going to disk, and the store is now inconsistent. If you don't have data you care about on the cluster, by far your best option is: 1) Figure
