I have 19 pages that are stuck unclean (see below result of ceph -s). This
occurred after I executed a "ceph osd reweight-by-utilization 108" to
resolve problems with "backfill_too_full" messages, which I believe
occurred because my OSDs sizes vary significantly in size (from a low of
600GB to a hi
If one node which happens to have a single raid 0 hardisk is "slow", would
that impact the whole ceph cluster? That is, when VMs interact with the rbd
pool to read and write data, would the kvm client "wait" for that slow
hardisk/node to return with the requested data, thus making that slow

I'm trying to maximize emphemeral Windows 7 32-bit performance with CEPH's

VMs are all ephemeral, but I am worried about performance and

When booting an image from Openstack in which CEPH is the back-end for both

In trying to download the RPM packages for CEPH, the yum commands timed
out. I then tried just downloading them via Chrome browser (
http://ceph.com/rpm-emperor/el6/x86_64/ceph-0.72.1-0.el6.x86_64.rpm) and it
only downloaded 64KB. (The website www.ceph.com is slow too)

We need to install the OS on the 3TB harddisks that come with our Dell

allow attaching an external harddisk via the PCIe slot. (I've tried

But, must I therefore sacrifice two hard disks (RAID-1) for the OS? I

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

I've recently accepted the fact CEPH-FS is not stable enough for production
based on 1) recent discussion this week with Inktank engineers, 2)
discovery that the documentation now explicitly states that all over the
place (http://eu.ceph.com/docs/wip-3060/cephfs/) and 3) a reading of the

them." So, should I assume that we can't do incremental file-system
snapshots in a stable fashion until further notice?
