Does the kernel version matter if you are using ceph-fuse?

This is a long-awaited bugfix release for firefly. It has several
imporant (but relatively rare) OSD peering fixes, performance issues when
snapshots are trimmed, several RGW fixes, a paxos corner case fix, and
some packaging updates.
We recommend that all users for v0.80.x firefly upgrade whe

You’re using a file system on 2 hosts that is not cluster aware. Metadata
written on hosta is not sent to hostb in this case. You may be interested in
looking at cephfs for this use case.

It has just been pointed out to me that you can also workaround this
issue on your existing system by increasing the osd_max_write_size
setting on your OSDs (default 90MB) to something higher, but still
smaller than your osd journal size. That might get you on a path to
having an accessible filesy

Thanks for the hints.
My original configuration is with " rgw print continue = false", but does not
work.
Just now I tested to change it be "true" and restart radosgw and apache2
service, strangely to see that everything can work now.

you should weight the OSD so it's represent the size (like an weight of

Nevertheless also with the correct weight the disk was not filled in

If you want to mount a filesystem on one block device onto multiple

Hi all!
I would like to expand our CEPH Cluster and add a second OSD node.
In this node I will have ten 4TB disks dedicated to CEPH.
What is the proper way of putting them in the already available CEPH
node?
I guess that the first thing to do is to prepare them with ceph-deploy

Hi,
if I want to clone a running vm-hdd, would it be enough to "cp" or do I
have to "snap, protect, flatten, unprotect, rm" the snapshot to get a as

Or: Does cp use a internal snapshot while copying the blocks?
Thanks,

Hello list,
I'm currently trying to understand what I can do with Ceph to optimize
it for a cold-storage (write-once, read-very-rarely) like scenario,
trying to compare cost against LTO-6 tape.
There is a single main objective:
- minimal cost/GB/month of operations (including power, DC)
