Hi Sage,
I went through the tiering agent code base and here is my understanding on the
agent behavior. Please let me know if that is correct.
1. Agent will be always in idle state if target_max_bytes or
target_max_objects not set on the pool irrespective of other tiering params set

Hi Mark,
I've been playing with the reweight on 3 of the OSDs (BTW each OSD is
backed by a HDD, with a SSD backing all the 4 journals on each host) and
these slower ones were given a reweight of 0.5, 0.66 and 0.66.
>From what I gathered the reweight would also reduce the number of I/O

Make sure the volume "volume-17d9397b-d6e5-45e0-80fa-4bc7b7998842” does no
have a snapshot or cloned linked to it , it might sometimes cause problems
while deletion.

I think I have a split issue or I can't seem to get rid of these objects.
How can I tell ceph to forget the objects and revert?
How this happened is that due to the python 2.7.8/ceph bug ( a whole rack
of ceph went town (it had ubuntu 14.10 and that seemed to have 2.7.8 before
14.04). I didn't kno
Yes, I use cloud-init with cloud-initramfs-growroot without other scripts.
I tested your advices within a fresh image, but poorly I do not see any
result. The only thing the log said about my mounts oder FS' is

Thanks Sage, this helps !

Hi to all,
I'm having some issues while trying to deploy a OSD:
ceph@cephdeploy01:~/ceph-deploy$ ceph-deploy osd prepare --fs-type
btrfs cephosd01:sdd:sde
[ceph_deploy.cli][INFO ] Invoked (1.4.0): /usr/bin/ceph-deploy osd
prepare --fs-type btrfs cephosd01:sdd:sde
[ceph_deploy.osd][DEBUG
Have you re-formatted and re-added all of the lost OSDs? I've found that
if you lose an OSD, you can tell Ceph the data is gone (ceph osd lost
), but it won't believe you until it can talk to that OSDID again.
If you have OSDs that are offline, you can verify that Ceph is waiting on
them with cep

How do I get ceph clients to start after a system boot?

For your RDB volumes, you've lost random 4MiB chunks from your virtual
disks. Think of it as unrecoverable bad sectors on the HDD. It was only a
few unfound objects though (ceph status said 23 out of 5128982). You can
probably recovery from that.
I'd fsck all of the volumes, and perform any app
