Thanks Sage. I'm not sure what is going on with librados2 (including rados and rbd for that matter). I'll see what I can do. - Luis On 07/15/2014 12:39 AM, Sage Weil wrote: Hey Luis, I pushed wip-dencoder, which moves ceph-dencoder to ceph from ceph-common. This avoids the dependency for

2014-07-15 Thread Alfredo Deza
Hi All, There is a new release of ceph-deploy, the easy deployment tool for Ceph. There is a minor cleanup when ceph-deploy disconnects from remote hosts that was creating some tracebacks. And there is a new flag for the `new` subcommand that allows to specify an fsid for the cluster. The full

Well I did end up putting the data in different pools for custom placement. However, I run into trouble during retrieval. The messy way is to query every pool to check where the data is stored. This requires many round trips to machines in the far off racks. Is it possible this information is

One of Ceph's design tentpoles is *avoiding* a central metadata lookup table. The Ceph MDS maintains a filesystem hierarchy but doesn't really handle the sort of thing you're talking about, either. If you want some kind of lookup, you'll need to build it yourself — although you could make use of

Hi, This is part of a larger pull request ( https://github.com/ceph/ceph/pull/1875 ), specifically https://github.com/dachary/ceph/commit/64175d9d6e1c8f6cbdc5396e85ba8c94168afba8#diff-8a5d2cfe0db7cb75615a5f6b2245148bL53 . But it's worth applying as suggested until it gets merged, to avoid

v0.80.4 Firefly released

2014-07-15 Thread Sage Weil
This Firefly point release fixes an potential data corruption problem when ceph-osd daemons run on top of XFS and service Firefly librbd clients. A recently added allocation hint that RBD utilizes triggers an XFS bug on some kernels (Linux 3.2, and likely others) that leads to data corruption and
