[ceph-users] Upgrade Woes on suse leap with OBS ceph.

So I updated suse leap, and now I'm getting the following error from ceph. I know I need to disable some features, but I'm not sure what they are.. Looks like 14, 57, and 59, but I can't figure out what they correspond to, nor therefore, how to turn them off. libceph: mon0 10.0.0.67:6789

[ceph-users] fibre channel as ceph storage interconnect

Is it possible? Can I use fibre channel to interconnect my ceph OSDs? Intuition tells me it should be possible, yet experience (Mostly with fibre channel) tells me no. I don't know enough about how ceph works to know for sure. All my googling returns results about using ceph as a BACKEND for

[ceph-users] RBD/Ceph as Physical boot volume

I posted about this a while ago, and someone else has since inquired, but I am seriously wanting to know if anybody has figured out how to boot from a RBD device yet using ipxe or similar. Last I read. loading the kernel and initrd from object storage would be theoretically easy, and would only

[ceph-users] ZFS or BTRFS for performance?

Insofar as I've been able to tell, both BTRFS and ZFS provide similar capabilities back to CEPH, and both are sufficiently stable for the basic CEPH use case (Single disk -> single mount point), so the question becomes this: Which actually provides better performance? Which is the more highly

If you can swing 2u chassis and 2.5" drives instead, you can trivially get between 15 and 24 drives across the front and rear of a beautiful hot-swap chassis. There are numerous makes and models available from custom builds up/down through used on ebay. Worth a peek. On Thu, Feb 11, 2016 at

Re: [ceph-users] Advises for a new Ceph cluster

In just the last week I've seen at least two failures as a result of replication factor two. I would highly suggest that for any critical data you choose an rf of at least three. With your stated capacity, you're looking at a mere 16TB with rf3. You'll need to look into slightly more capacity or

Re: [ceph-users] Advice saught

I can only comment I the log. I would recommend using three logs (6 disks as mirror pairs) per system, and add a crush map hierarchy level for cache drive so that any given pg will never mirror twice to the same log. That'll also reduce your failure domain. On Jan 29, 2014 4:26 PM, Geraint Jones

[ceph-users] images in bulk offline storage

There are some seldom-used files (namely install ISOs) that I want to throw in ceph to keep them widely available, but throughput and response times aren't critical for them, nor is redundancy. Is it possible to throw them into OSDs on cheap, bulk offline storage, and more importantly, will idle

[ceph-users] Ceph vs zfs data integrity

What guarantees does ceph place on data integrity? Zfs uses a Merkel tree to guarantee the integrity of all data and metadata on disk and will ultimately refuse to return duff data to an end user consumer. I know ceph provides some integrity mechanisms and has a scrub feature. Does it provide
