Hi all,
I am installing ceph on ubuntu 14.04 desktop 64-bit VM using the link
http://eu.ceph.com/docs/wip-6919/start/quick-start/
But I got following error while installing ceph

Sage,
would it help if you add a cache pool to your cluster? Let's say if you add a
few TBs of ssds acting as a cache pool to your cluster, would this help with
retaining IO to the guest vms during data recovery or reshuffling?
Over the past year and a half that we've been using ceph we had a

Hi Pierre,
Unfortunately it looks like we had a bug in 0.82 that could lead to
journal corruption of the sort you're seeing here. A new journal
format was added, and on the first start after an update the MDS would
re-write the journal to the new format. This should only have been
happening on t
Hi cephers,
We are investigating a backup solution for Ceph, in short, we would like a
solution to backup a Ceph cluster to another data store (not Ceph cluster,
assume it has SWIFT API). We would like to have both full backup and
incremental backup on top of the full backup.
After going throug
Hi,
If you are using the experimental filesystem component of Ceph, and
you use the less stable "numbered" Ceph releases, you should be aware
of the following issue affecting the 0.82 development release:

This issue introduces a risk of corruption when first st
Thank you, Greg!
I solved it through creating MDS.

I'd like to see some way to cap recovery IOPS per OSD. Don't allow
backfill to do no more than 50 operations per second. It will slow
backfill down, but reserve plenty of IOPS for normal operation. I know
that implementing this well is not a simple task.
I know I did some stupid things that ca

There are two command line tools for Linux for LSI cards: megacli and

You can do pretty much everything from those tools.

Thanks for the info, I sent them a message to inquire about access.
In the meantime, the mirror is already synchronized (sync every 4 hours) and
available on http://mirror.iweb.ca or directly on http://ceph.mirror.iweb.ca.

Hi,
I have question on intention of Ceph setmaxosd command. From source code, it
appears as if this is present as a way to limit the number of OSDs in the Ceph
cluster. Can this be used to shrink the number of OSDs in the cluster without
gracefully shutting down OSDs and letting recovery/remap
